- TPTravis P.Verified BuyerReviewingOS-01 HAIR | 3 Month Supply RefillsI do not recommend this productRated 2 out of 5 stars2 days ago6 months no results
Two 90 day refills. I don’t see any better thicker hair. Have been using with monaxidil. I have more faith in Costco monaxidil. Will continue with that and cancel one skin. Was hopeful.
OneSkinYesterdayThank you for sharing your experience with OS-HAIR. We’re sorry to hear it hasn’t delivered the results you were hoping for. We understand it can be discouraging when progress is slower than expected.
OS-HAIR was formulated with our OS-01 peptide to support scalp and follicle health at the cellular level, and timelines for visible improvement can vary from person to person. It can also be used alongside minoxidil, as they work well together—OS-HAIR supports scalp and follicle health, while minoxidil helps stimulate the hair growth cycle, addressing hair health from two complementary angles.
We appreciate your feedback and respect your decision to continue with the option that feels most effective for you. If you ever have questions or would like support in the future, our team is always here to help.

Just finished my first 3 months. I'm not sure that I'm seeing regrowth yet, but I do feel like it has slowed the hair loss. Hoping for more noticeable effects in the next 3 months!
OneSkin3 weeks agoThank you for sharing your 3-month update, Crystal! It’s great to hear you’re noticing less shedding — that’s one of the first visible signs that OS-01 HAIR is helping rebalance the scalp and reactivate the natural hair-growth cycle.
In our clinical study, 75% of participants observed new hair growth and 72% reported decreased shedding after 3 months — with even greater improvements in hair density (+40%) and thickness (+43%) after 6 months. You’re right on track, and continued consistency is key to seeing fuller, stronger results ahead. We can’t wait to hear how things progress in the next phase of your journey

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.
OneSkin3 days agoThank you so much for your wonderful feedback, Barbara! We are absolutely thrilled to hear that OS-01 HAIR has been so effective for your husband. It's amazing that you're seeing such great results with his male pattern baldness, and we really appreciate you taking the time to share those before and after photos with us. We're so glad you found a solution that's working so well and truly appreciate you sharing your experience!
