    OS-01 Hair

    I bought this for my husband in March. He has male pattern baldness. And I was looking for a non-invasive product that would work. It has stopped his hair falling out and had mild success with new hair growth. I am posting two pictures of when he started and two pictures of today.

    Still waiting to see the benefits

    I have been using this religiously every day as part of my evening routine hoping to see re-growth of hair which has started to fall out around the front of my hairline- which has been very distressing as I have always had great hair but now i have hair that won't grow around the front of my scalp and I have yet to see any improvement- I have taken 'before' photos and am continuously comparing. Also being at the front of my hair, it would be very noticeable if there was a positive change.

    I have ordered again and will continue for at least another 3 months to see if patience and persistence does pay off! Crossing my fingers.

    Hi Catherine!

    Thank you for the review and for giving OS-01 HAIR a shot!

    Consistency is key, and we typically recommend using OS-01 HAIR twice daily for at least 3 months to start seeing results.

    Hair growth follows a complex cycle—anagen (growth), catagen (transition), telogen (rest), and sometimes kenogen (lag)—and it takes time for follicles to regenerate and produce new strands.

    In our 6-month clinical study with men and women experiencing hair thinning, participants using OS-01 HAIR (plus dermarolling) saw significant improvements:
    +39.62% increase in hair count per cm² after 6 months (86.67% of participants)
    +9.97% improvement in follicle spacing after 3 months (70% of participants)

    One Skin, Great Hair

    I've been using OS-01 Hair for about 6 months and I can see so much growth around my hairline! Where my hair was starting to thin, at my part, it's now thicker, and i feel like the new growth has less grey in it. I'll keep using this product!
