I have very sensitive hair and scalp and I often had dandruff problems. I used Head and Shouldres for many years, but the problem with it was that after a while it produced me dandruff again. Vichy was wonderful: it cleaned my hair really good, it got rid of the dandruff and I used to alternate it with a lighter shampoo because this one is a treatment shampoo after all, as they told me at the pharmacy. However, I stopped using it for 3 reasons:
1. The price. After using a bottle/month for half of year, I came to the conclusion that it was just too expensive.
2. The size. It's soooo tiny! I have long hair and I wash my hair very often, so I had to buy it monthy. Yes, alternating it with another shampoo, so imagine!
3. If you stop using it, your hair will come back to its original state: dandruff, itchy and opaque. So how is it a treatment? A treatment for life?
I returned to Head and Shoulders. It does the same, it's just as addictive, but at least it's cheap and it's bigger.
