    Worth the Cost!

    I've been using now for about 5 months. I must say after spending alot of money on different hair serums for my hair shedding and lack of growth, multiple dermatologist. THIS ONESKIN WORKS! I thought I was seeing things after 4 weeks, that my hair was shedding ALOT less and thought...NO I'm imagining things. The truth is that it was shedding alot less! I continue to use daily and TODAY I noticed growth around my hair line, which was thinning badly. I highly recommend. I can't say enough about this product, other than if you are thinking about it...JUST TRY IT, you will not be disappointed.

    Better than Rogaine

    It is amazing how within one week of once per day usage with roller my husbands hair was healthier . No frizz or dryness . Just shiny with the appearance of fullness. With one 2 weeks his thinning hair (back of head) started showing signs of hair regrowth. He could not believe the difference in both hair texture and health compared to his Rogaine experience that left his hair dry, frizzy and very little change in volume.

    I love this product!

    After having 4 kids & going through menopause, my hair was in need of some new growth. It was thinning & needed help. I started the OS-01 hair a year ago. I now have lots of regrowth & it is coming in so much thicker & faster than it has in years! Thanks One Skin, for another amazing product, that really works!
