Overpriced and doesn’t make a difference. I’m so serious I’ve tried every product from this line and it’s just aesthetic marketing, don’t fall for this!

Drying hair too much

[This review was collected as part of a promotion.] I got a sample and just with one wash I felt my hair being more dry than ever, nothing compares to it, not even the cheapest shampoo. I gave it another try (since I had some of it left) and same result. I regret using itregret
