They have been proven to be one of the best out there, but as others have said…pricey. I believe that the main thing is to have a good conditioner so if you splurge on anything, splurge on that. It is very hard to get on that will detangle your hair, but also leave it light and not weighed down. Kerastase is very good for that. You can throw in a cheaper shampoo and you will save money as well.

i guess they are okay if you’ve herd of it
They are the best. They are a bit expensive though. But it´s worth it. I´ve been using Kerastase Oleo Relax products for my hair for 4 years now. When my budget is a little tight I use Pantene instead.
