Kerastase Nutritive Bain Oleo Relax is a nice shampoo. I have tried many of the Kerastase products and have yet to find one that I do not like or that does not give good results. They are all fabulous and worth the extra money that you pay. Oleo Relax shampoo is very nice and gives great results. I would recommend it for people who have stressed, dry, damaged, or unmanageable hair. It really adds the nutrients and vitamins that you hair is striving for and makes it look and feel so much nicer. You can use it either for long, short, straight, or curly hair. You only need a small amount and the bottle should last you a long time, especially if you have dry hair and do not need to wash your hair everyday. The smell is very nice and not too strong or overpowering. Also you will get best results if you use the shampoo with the conditioner, mask or leave in treatment. Any of these will enhance the results from the shampoo.
