I am using Regen hair vitalizer since one year. It had stopped my hair loss after using for 3 weeks, but there is not hair growth after using for more than year now.
Useless product. When I asked company representative after three months they told it normally take 2-3 months for new hairs to grow in most cases, but can take little more time in other cases. I tried for one year now and it is no hair growth and marketed by them.
DO NOT BUY SUCH PRODUCTS.
