Best EVER
I have used biolage off and on for years. The salon I went to used a different product so I switched. My hair became hard to manage, dry and dull. I recently went back to biolage and used the smoothproof for the first time. I could not be happier with my decision. My hair is soft, smooth and shiny a...

New bottles have less product
This is a good conditioner. New bottles have less product for same price though. I will not purchase again.
This conditioner is good but is expensive
Hair Type Straight Hair
I use it when my hair gets wavy, tangled or dry.
Horrible
With this price point, i thought for sure it would at least be decent. Almost the worst conditioner ove ever used. I brish my hair while conditioner is still in it wbcause my hair is super thick and curly. Its the only way i can manage. My hair rips right out with this. It doesnt smooth. It doesnt detangle. Dont waste your money.
Don't waste your money
Bought this because reviews seemed positive. But as a girly with thick and super frizzy hair this is an absolute NO! Left my hair with like a weird film on it and even after using it my hair felt super greasy like I hadn't even washed it. Do not waste your money on this.
Amazing
First time trying was recommended this
