Amazing! My hair is fried from bleaching black to platinum without any Olaplex type products + regular use of hair dryer and straightener without heat protectant spray. If my hairdresser knew what I do to my hair, she'd have a stroke. This conditioner makes it feel so soft and silky, it doesn't look or feel at all damaged so my hairdresser is none the wiser. Also does a fabulous job of getting rid of the brassy tones, leaving it a lovely platinum ash shade. I pair it with the shampoo for best results.
