Kerastase Resistance Bain Therapiste Shampoo, 15 Oz

I realize this is expensive. A little really does go a long way. It is thicker than most shampoo. I have short naturally curly hair and a less than a Nickle size is more than enough. I would think it wouldn't take much more for longer hair. I don't wash my hair every day but I do condition it with the conditioning mask. Let it set while I shower. The little oval size container. Again a little goes a long way. These are the best products for extra moisture and softness. I wouldn't use too much as to not make your hair feel heavy. Besure to rinse thoroughly. I think they are worth the money. Sometimes you catch them on salle. I used to use the curly set and while it too is a great product, I like this one for more moisture.
