Hello, I use the product for about 1 month. I had hair like straw, I tried umpteen of prior products. Kerastase My hairdresser told me there is nothing better. As for me, I am delighted, I wash my hair with shampoo bath strength of the same color and soon my hair has changed in appearance. They are softer, much less dry and I finally found my subject. I am very happy with this product and I recommend it.
