Hi Harley,Hi Harley,

Thank you so much for taking the time to share such honest and detailed feedback after 9 months with OS-01 HAIR SCALP SERUM. We truly mean it when we say we appreciate your patience, your commitment to a strict routine, and your willingness to see the full year through. That kind of dedication says a lot about you, and we genuinely don't take it for granted.

We can hear how frustrating and disheartening this has been — especially when you've invested so much, financially and personally, with such high hopes. Please know that your experience matters deeply to us, and we want to do everything we can to help before you reach that one-year mark.

We do want to gently clarify one small thing: our clinical results show that 81% of participants saw a +40% improvement in visible hair density — the figure you may have seen quoted as 85% is a slight misremembering, but we completely understand how these numbers blur together! More importantly, those results came from a 6-month double-blind, independent, third-party clinical study where participants used OS-01 HAIR twice daily alongside a dermaroller once daily. Both elements together — the serum and the dermaroller — were part of the protocol that produced those impressive results. If the dermaroller hasn't been a consistent part of your routine, that could genuinely be a meaningful missing piece, as it helps the OS-01 peptide absorb more deeply into the scalp and has been shown to significantly optimize results.

We also want to be honest with you: OS-01 HAIR is specifically designed to target cellular senescence in hair follicles — one of the key drivers of age-related hair thinning — but hair loss can have multiple contributing factors, and individual responses do vary. That doesn't mean we're giving up on finding something that works for you — quite the opposite.

We would love to personally connect with you before your year is up. Whether it's reviewing your application technique, discussing the dermaroller, or just making sure you feel fully supported, we want to be in your corner. Please reach out to us at support@oneskin.co — we're here for you and we genuinely want your investment to feel worthwhile.

Hi Jennifer,

Six months of consistency is no small thing — thank you for sticking with it and for sharing such an honest, detailed update. Your patience and self-awareness about this being a long process genuinely means a lot to us.

The growth and strand thickness you're noticing are real, meaningful signs that the OS-01 peptide is doing its work at the follicle level. Early clinical results show that after 3 months, OS-01 HAIR increased hair density and thickness — so what you're feeling in the strands is consistent with what the science predicts. As for the crown area, we hear you, and we want to be honest with you: the top of the scalp, where hair is often the thinnest, tends to be the last area to respond visibly because follicle activity there has typically been suppressed the longest. That doesn't mean it won't come — it just means it's working on a longer timeline than the areas where growth was already closer to the surface.

One thing worth mentioning: the clinical study was conducted with participants using OS-01 HAIR twice daily alongside a daily dermaroller, which significantly improves peptide absorption into the scalp. If you're not already using a dermaroller, it may be worth exploring — it could meaningfully accelerate the results you're working toward, particularly in that crown area.

We'd love to connect with you directly to talk through your routine and make sure you're set up for the best possible outcome. Please feel free to reach out at support@oneskin.co — you've invested six months in this, and we want to make every one of them count.

Thank you for trusting us, Jennifer. We're rooting for you.
