Don't buy this product! It is a rip off..does not work..used for the first month and lost more hair than I had when not using it!...I wanted to give it a fair trial, they recommended that I continue to use it at a reduced cost..half price, so I did ,but it just got worse with no sign of hair regrowth. It eventually after 6 weeks burnt my scalp and made it so dry that it resembled "Crusty cradle Cap"! It also affected the skin around my scalp...made it extremely dry! Thank goodness I had the sense to cease using it immediately! After calling the company several times I was told that "we have thousands of satisfied users" I would like to know even one of them that is satisfied! Its just a big scam ...preying on people who would really just like to improve their hair quality!
