i like the price of this conditioner. For the price my hair did feel clean and not limp. The condition did it job and took the dry frizzes away and made it look smooth

Great lightweight conditioner that actually smooth's hair and frizz. Loved the fact that this conditioner (even the shampoo and leave in cream) didn't leave my hair feeling heavy or full of gunk like most smoothing products do. Plus it made my hair smell great.

Un des meilleurs revitalisant que j'ai essayée! Il laisse mes cheveux tellement en santé, tellement hydraté et tellement doux! Jamais un shampoing a aussi réparer mes cheveux que celui-ci!

Ce keratine Smooth Conditioner à réparer mes cheveux en un seul claquement de doigt! J'avais les cheveux brillant, hydraté, doux et en santé! Il est un des meilleurs que j'ai essayée!

This conditioner works really well! Combined with the shampoo, it leaves my hair feeling soft and smooth, but not weighed down! You don't need to use a lot to get good results!

I'm in love with the TRESemmé Keratin Smooth System Conditioner. I've really bad hair and since I've started using the keratin smooth system conditioner I've found that it leaves my hair feeling so smooth. I use this conditioner with the keratin smooth system shampoo. Works amazingly.

This is probably my favourite TRESemme product of all time. It is very dependable and always gives me the same great results. I have really frizzy, thin hair and have a hard time finding a product that will smooth my hair without weighing it down. This conditioner always leaves my hair very smooth, soft, and shiny, without weighing it down and making it look limp. It smells great and is pretty cost effective, which is always nice. When I use this conditioner I use the corresponding Keratin Smooth shampoo.

This conditioner is great. When used in combination with the shampoo, and the heat activated treatment before flat-ironing, it definitely leaves hair smoothed and frizz-free for days. I definitely would recommend this to anyone with wild, unruly hair or for anyone who flat-irons a lot! I can go 3 or more days between straightening with these products - it makes my hair stay straighter longer.

I personally and highly recommend this product! I would agree with the comment below, I really would say it rebuilds damaged hair and leaves it feeling and smelling very nice. 10/10
