hair derma
I bought it because of my severe hair loss and at the request of my dermatologist, who prescribed other, much more expensive products. Out of compassion, he thought Prozis was just as good or better. I'm delighted with both the price and the quantity of the containers.

Brilliant
Combined with biotin, its effect is noticeable. My nails are stronger and my hair grows faster. You'll notice that hair in other areas also grows faster, BUT NOT THICKER. For example, I used to pluck my eyebrows once a week, and after using this product, I only pluck them twice a week. For me, it's totally worth it, as it works wonders for both nails and hair.
