I have bought the whole range (shampoo, hair mask, spray) and I haven't seen any results after 3 months of use. Unless it was to make my hair fall out more and the product prevented it. Apart from that, I haven't seen anything positive. As hair products, they clean well and leave a nice scent and soften the hair. Maybe I would give it another chance for another 3 months to see if I see any results, but I doubt I will see any difference since there should have been results in the first 3 months.
