Not great
Didn't absorb into my hair well, leaving it greasy. Really wanted to see amazing results but just didn't.
Works!
This definitely works, just need to be patient & persistent. It does make me hair a bit greasy but I could be using it excessively.Definitely noticed hair growth
Did notice the growth, but not enough to purchase again. Also, where I was using it my hair started sprouting greys! But I may just be in denial..No difference
The first time I used this, I felt a slight tingle on my scalp, which wasn’t irritating and dissipated fairly quickly. Because of the tingle though, I expected to see a difference but I’m almost finished the bottle and still can’t see any difference. Won’t re-purchase.Worked wonders
I purchased this for my aunty as she was recovering from chemotherapy (cancer free!). She said it worked wonders and I can say now, a year later, her hair is thicker than ever!Pop eye's girlfriend
I really wanted to like this, but my hair feels limp the day after application.The name says it all
It gives density to hair and makes hair look more fullerThe name says it all
It gives density to hair and makes hair look more fullerGave me a rash
This serum gave me a rash around my hairline where I was using it. Didn’t get to use it for long so can’t comment on how effective it is.Definitely need to buy !
Have been using going on the 3rd month and honestly my hair has so many baby hairs of new growth and hair just feeling thicker and shiner than ever.Really good
I really love this product. Doesn’t leave a residue and feels light weight. I’ve noticed results after 1-2 months of useNothing noteworthy
Didn't notice any benefits, unfortunately. It also made my hair a bit greasy. Therefore, I would not recommend to those with fine or low pororsity hair.First impression good
I’ve tried this once (one bottle) and the results show. About to buy my second and going to get better and more visible result. Love it’sHmmm not sure
Wanted to love this, but didn’t notice a difference, if you dermaroll your fine areas or massage this in maybe you’ll see results but I wouldn’t reccomendBaby hairs
I didn't think this was working but close to nearing the end of the bottle I started seeing a fresh crop of baby hairs appear at my hairline, so patience might be necessary. One star off because I found it hard to apply and distribute the recommended amount over my whole scalp in comparison to other products I've used, and if I used too much trying to get good coverage it made my hair look a bit ...Read MoreI love it
Great serum so good , really seen a difference with hair densityI think it's working!
Definitely seeing more baby hairs, and seeing them grow quicker than usual. I find that it absorbs pretty well and doesn't make hair that much more oily. Hair oils usually make my hair oily but this absorbs and is textured more like waterGreat hair product
I have been searching for a leave in hair treatment for hair growth. It doesn't make my hair greasy (I have thin hair, that grease easily). It makes my hair look shinier, fuller and very soft. I can't tell much about hair growth yet, I haven't been using it that long.Noticed more baby hairs
This definitely works and i didnt even use it consistentlyGreat
I enjoyed this product the texture was great and it did not weigh my fine hair downMy fiance started using this too!
Bought my first bottle in 2021 and this has been my third purchase. Safe to say, my partner has started using this too! I would suggest to use as recommended, otherwise it will leave your hair looking like it was slightly treated, but not oillyyNice
Perfect for hair density and renewing hairPostpartum saviour
Helped me with hair growth after having a baby. My hair fell in chunks soo after baby. This serum has definitely helped me get hair on my front part of the head. One bottle can last a few months.Amazing
Perfect for hair density and renewing hair. Highly recommended!OMG New hairs all around my hairline in only a few weeks.Wow.
Ok I love this brand and their products. I would ask it to marry me if I could. Their skincare is amazing and now this. Hair.Awesome hair products. I have been casually using this product on my scalp only 2 or 3 times a week for only 3 weeks. This morning I am looking at my forehead and there is all this hair around my hairline and other little hairs about my head. I am thinking are these very sho...Read MoreBaby hairs galore
It has brought on the baby hairs and everyone says my hair looks healthier. It does not feel as though it transfers well around the headOkay
I used it daily for about a month as I have oily hair so could not cope with leaving it in while I slept. I would wash my hair in the evening and then apply mostly to the front and top of my hair line in the morning, massaging into the roots. It's not oily but leaves hair looking a bit wet. I sore no increase in hair growth but it was only left on my head for maybe 14 hours a day so might work be...Read MoreIts ok
ive heard good things about this product but its just makes my scalp too oily to use every day so i use it in my hair the night before i wash my hair.its okay
Its an alright product, a little annoying to use as you feel like you cant cover your whole scalp, and honestly i saw the same, if not better results from using hair vitaminsWork
I've seen baby hairs starting to grow. Will keep usingRepurchase
Non-sticky formula without obvious scent, really improved my scalp acne and made it grow some new hair, always repurchasing!Baby hair!
I have baby hair in places I havent seen in a whilCool
I have baby hair in places I havent seen in a while. I suffered hormonal hair loss. hair grows a slower than wed think so really be consistent and give this product a whileEffective
Great especially with long term use. Can make my scalp a bit oily at the time, so need to be careful not to apply too much.Best serum
Love this serum. Easy to use and non sticky which can be used everyday. You wont notice its effect immediately but after few weeks i can definitely see baby hair growing.I think it works...
Used it for a month and applying this as generously to my scalp. I've seen baby hairs starting to grow. Will keep using to get my hair more fuller and denser.Will repurchase this
I am liking this product. I feel the density of my hair has improved, and it feels as thick as when I was in my early 20s. It is a runny liquid, not a thick serum. Only use a little bit and you can always add a bit more. I like to really concentrate on the roots and massage it into my scalp. I also run a little bit through my eyebrows. I like The Ordinary line of products. I will also be purchasin...Read MoreDont think it works
It was good to smooth out my frizz but other than that i dont think it does anything to stop hairfall i do not think that i will buy it againkind of split
I am a bit split in this product. I definitely have some baby hairs coming in but it doesn't make my hair look good. Makes it look dirty. I think I would rather have less baby hairsGlad I persisted, baby hair all over!
I have baby hair in places I havent seen in a while. I suffered hormonal hair loss. hair grows a slower than wed think so really be consistent and give this product a while.Would repurchase
I bought this for my husband, he was experiencing early balding at the crown of his head. This has actually really improved his hair texture. We took a picture when I started using this on him and another after 3 months, there is a clear improvement in hair density. I also make sure to give him a bit of a head massage every other night when I apply this for him.God Send
I bought this just to try after seeing a review about how it helped with itchy/flaky scalp. I have awful seborrheic dermatitis and after years of experimenting, found a holy grail shampoo (SachaJuan scalp shampoo) that significantly controls it. I wash my hair twice a week: x2 shampoos, condition, nourish ends, dry, hair mask once a month. I added this into the routine by applying straight to th...Read MorePretty good
Works really well, will repurchaseHair density treatment
I was hoping this would thicken up my hair but it actually made my long curly hair get quite knotty & clumping under my neck. I didn't reuse it along my hairline where my hair is receding so I can't say whether it wouldve worked as a hair growth, which it may but I stopped using it as my frizzy hair gets knotty enough without using the hair serum. Maybe I shouldve only put it on my scalp, I'm not ...Read MoreImpressive
Non-sticky formula without obvious scent, really improved my scalp acne and made it grow some new hair, always repurchasing!It works!
I've been using this every night for a month now and holy moly my baby hairs have grown like weeds!! I've had little bald patches nothing would ever work to grow out and I finally have hair there. Cannot express the relief that this works. So happy I could cry! I wish I could add before and after pics!Love this serum
I used a few drops every time I washed my hair and now its shinier and healthier.Great product
I have thin, oily hair and this product made my hair more voluminous. All you need is a few drops and rub it into your roots. Would recommend.Surprisingly it works
I wish I could upload a photo to show all the baby hairs I have along my hairline where I have been applying it The evidence of this working has appeared only about 2 months after I had started using it and only 1 or 2 times a week when I could rememberMy hair loves it
Its not oily and it makes my hair look healthier and vibrant.Oh my god.
After having a baby I noticed some significant thinking around my temples. I hated it! I had been eyeing this one off for a while - as a fan of The Ordinary - but didn't think it would really do much. I finally bit the bullet and bought it and OH BOY. I have been using it for LESS THAN ONE WEEK and have noticed drastic results. I'm talking complete turn around. My hair has begun to grow back in a...Read MoreBaby hair no more!
This product really worked for me. I've had very fine hair for years now probably not helped by lifestyle choices and a period of bleaching my hair. It never really recovered and was exactly like a 3years old in texture, very fine and I was starting to be able to see my scalp in patches. I started using this about 8 months ago, it does take a month or two of using to start to see results. I notice...Read MoreUnfortunately didn't see any difference
I bought this for the small baby hairs at my left temple as I have thinning hair in that area. I tried this for 6 months. Unfortunately I didnt see any difference with this product which is a shame. I use alot of the ordinary and love the brand, so a shame this one didnt work for me.Oily
I don't really like this - applying oil to my roots makes my hair oilyNot sure if it works
This feels lovely but I am not sure if I am seeing resultsLove it!
Have been using this for a few months now and definitely noticing an improvement in my hair and scalp quality!Great product
I've been using this for the past few weeks and have noticed a difference. My scalp feels less irritated and my doesn't fall out as muchThis product needs to use continuously if you want to see result.
This product needs to use continuously if you want to see result.Promising
I've been using this on my hairline and my eyebrows (over-plucked as a teenager), and so far I am seeing some baby hairs growing, and it looks like they're starting to fill in. This is pretty surprising to me as I've tried castor oil and all sorts of other things before. Fingers crossed for more. Also the consistency is really good.not bad
its not oily, and make my hair line looks full and healthyNo chage so far
I have bee using this product for the past month but haven't seen any change in my hair so far. Will keep using and update if there is any change.Use when due for a hair wash
I have been using this product for a month now, and haven't noticed any difference. However, I am hopeful over time I will notice a change, especially as I haven't used much of the bottle yet. My recommendation would be to use it closer to when you are due to wash your hair, so the oiliness isn't as noticeable. This has worked for me!Leaves a residue
I wasn't able to use this for too many consecutive days as it made my scalp a little itchy and it left my hair feeling tacky and greasy-looking, despite the texture of the product being watery.Actually works!
Like all hair density products i was a little skeptical however after using this for a few weeks I’ve already notified my baby hairs around my face have been growing out and have definitely become thicker! I’ve been using every few nights just before i go to bed, I haven’t noticed it making my hair greasy at allHair gets less oily
Continue using this product for a while, to be honest, it's as good or even better than Aveda I would say. At this price point, it's hard to find something to beat it. I have recommended all my friends and families to try this. I used to wash my hair every couple of days, now I only wash my hair every 3 days. Hair gets less oily after using the product. I can't see hair density increase but hair d...Read MoreNot much change
I have been using this for a while now, but have not any difference to my hair.ordinary
love this product i have notice a difference in my hair line my hair feels more fullHave helped thicken my hair
I used to have very lush hair which has gradually thinned with age. I started using this before bedtime a few months ago but I haven’t used it very religiously. I don’t find it greasy at all and I use very generous amounts each time, but then my hair is very dry, so it might be better for dry hair than for normal hair. This serum has helped thicken my hair either by promoting regrowth or preventin...Read MoreNoticed Results
I've noticed results having used this product. My hair is definitely stronger and I'm noticing fewer breakawaysNot really effective
I used this product for about six months - two bottles worth - to try give it as much time to take effect as possible. I haven’t really noticed much difference in the thickness or density of my hair and it certainly has done nothing to help my thinning hairline. I was applying this before bed, so the greasy effect didn’t really bother me, and it had usually dissipated by morning, leaving my hair q...Read MoreLOVEE
This is the best. It has a neutral smell and makes your hair feel so healthy, strong and luscious.Great
This is pretty easy to use and implement into your hair care routine, I love the ordinary productsnot sure
not sure on these, did not notice much and it is hard to get the product all over your scalphair serum
can be greasy so I only wear to bed, but otherwise it seems to make my hair less prone to breakagehair peptide serum
personally didn't notice many results from this, it made my hair greasy and didn't absorb. Would recommend wearing a nightcap over this when you use overnight to reduce the greasy feelingTruly works- it has filled in my bald patches!
I have quite a few patches of hair missing and this product did as promised! Not only have the hairs filled in the sparse areas but my hair no longer sheds as much. It is a game changer! I will continue to repurchaseGreat stuff
I have genuinely noticed a difference in my hair with this serum! Lots of new baby hairs are growing longer, making my hairline look good. Added bonus, seems to hydrate my scalp and dryness/flakiness is reducing.Amazing Product - great addition for hormonal hair loss
I love this product, swear by it. I have struggled with male pattern like hair loss for years with thinning around the hair line and temples . Whilst I have worked on my hormones internally I never tried anything to support topically. This stuff works to help restimulate the hair from the outside! I recommend massaging it in into the scalp or rolling with a face roller before and after to ensure t...Read MoreIt’s working for me
I have been using this serum for just over a couple of months. I’ve been trying to use it every night but I am abit hit and miss. I feel like my hair is more fuller/thicker but I wasn’t sure if this was true or just my imagination. To my delight though, yesterday I went for my first hair cut since COVID and my hairdresser commented on all the new growth she noticed. She said I have so many new bab...Read MoreDried my hair out
I have fine hair that is bleached (last time was 6 months ago) the first few times I used it no problems sneaks nice didn’t make my hair oily. Then all of a sudden I had uncontrollable frizz and my hair began breaking off.Hair oil heaven
Love this product, I have never used anything like this before but it was great for taming my small fly away hairs that I seem to suffer with after having kids. I have recommended it to a few friends that have the same issues as well.Honestly not sure
This seems like a very hit or miss kind of product and for me personally, I didn't notice a great deal of effect after using this for several months. I did however like that it wasn't as greasy as I was expecting - it actually sort of gave my roots a bit more volume! I love other products from The Ordinary but I'm just not sure about this one.Patience paid off so well!
The serum really works guys! You just need to use is with consistency. My hairline has been revived before I finished my first bottle!! Amazing product!Patience paid off so well!
The serum really works guys! You just need to use it with consistency. My hairline has been revived before I finished my first bottle!! Amazing product!Makes hair look thicker
The serum makes my hair look thicker and more voluminous. It absorbs well on my scalp and doesn’t leave oil/ residue. I am not entirely sure about any increase of hair growth, but I like the ‘thicker hair’ feeling so will continue on using this serum.Ideal for thin hair
I used this every night after washing my hair, and I noticed after a few weeks that my hair felt a bit thicker and healthier.Slow improvements
My hair has been bleached and coloured numerous times over the past 5 or so years. Breakage has reduced since using this, which is a plus. My hair is becoming more glossy.
It takes a while for the product to absorb into your scalp so best to not apply before you sleep- product might just end up on your pillow .Not sure...
It’s hard to spread the recommended amount of a few drops to the entire scalp, and when I use more, it leaves my hair looking greasy. I found it a bit annoying to use, so I bought Kerastase Densifique and am now using that instead.BEST FOR THIN HAIR
I have thin hair, I have been using this product for a month every night with inversion method massage and I noticed a change in my hair texture its not like from thin to thick but my hair feels healthy and also if we apply this on healthy hair growth areas it makes it thicker&healthy and also generates new hair follicles.
I have started using derma roller in-accordance with this ser...Read MoreNot sticky and easy to absorb
It has a water-like texture and is very absorbed. Suitable for use after washing hair. But it needs to be applied by hand. People with oily scalp also feel happyNot great
Didn't absorb into my hair well, leaving it greasy. Really wanted to see amazing results but just didn't.great product
loved it, it definitely made my looks and feel healthier. I have curly hair and tried all sort of products to lessen the loss of hair and reduced thinning of my hair. will repurchase.Did not work for me
Used this for months and saw no lessening of hair fall and no increased hair growth.
Switched to the much more expensive Densifique Femme and got the results I had been hoping for.Where have you been all my life ahah
I have tried so many expensive brands when it comes to scalp’s treatments, oils,etc. I loved this one so much! It doesn’t oil your hair, you can see a root lift straightaway and over the time the head condition gets better :) so reccomended!Not too oily
This product has definitely made my hair fall out better. It doesn't make my hair oily and the one bottle goes a long way. definitely recommendGood product
This product has definitely worked for me. I have seen a lot of varying reviews.
My boyfriend has even said my hair is looking thicker ( I had all my hair snap from elbow length to shoulder length post a botched bleach job 3 years ago) Since then my hair has mostly grown back now and sits at boob-length but some parts are not quite even and I am unwilling to cut what has grown just to match ...Read MoreHappy hair
I found that I had to use about 3 drops of this consistently to start seeing results. I also found that it made my hair oilier faster than usual.Good product!
Good product but takes a while to show some resultno difference in hair growth BUT
No difference in hair growth/hair loss but I did notice any subsequent hair growing from where I applied it grew healthier and stronger. Undecided if I will repurchasereally good product
I love this, I have had so much new growth on my hairline and am not even halfway through the bottle! You have to be careful not to use too much or you'll get oily hair the next day, but with a few uses you'll get used to it!!Silky Smooth
I like it, it doesn’t oil my hair which is a huge plus for me! Still needs to finish the bottle to see the difference!
