community FDA Policy Shift Explained: What It Actually Means for PP405, VDPHL-01, Breezula and Hair Loss Drug Timelines

in Research/Science 42 upvotes 7 months ago

The FDA policy change may speed up approval for hair loss drugs like PP405, VDPHL-01, and Breezula by potentially eliminating the need for a second confirmatory Phase 3 trial. Approval timelines could be as early as 2028 for some treatments if Phase 3 results are strong.

community Recent trials investigating mesenchymal stem cell derived exosomes demonstrate significant increases in anagen duration and hair shaft caliber by upregulating Wnt/beta-catenin pathways.

4 upvotes 1 month ago

Exosomes from mesenchymal stem cells can increase hair growth by enhancing anagen duration and hair shaft thickness through the Wnt/beta-catenin pathway. Phase 2 trials show improved hair counts over 24 weeks.

community Microneedling must reach the stem cells in the upper hair shaft

82 upvotes 4 years ago

Microneedling should target depths of 0.5mm to 1.5mm for hair loss, with weekly sessions at 1mm recommended. Combining microneedling with Minoxidil is common for improved results.

learn oleic acid

Is there a difference between getting Oleic Acid from oils (like olive oil) versus hair products? Oils on the hair act mainly on the hair shaft and skin surface; eating olive oil is linked with heart health in cohort studies. Neither route has been shown to affect hair growth.
How does Oleic Acid support hair follicle strength and growth? Lab and animal studies suggest oleic acid may help the scalp barrier and hair shaft. No human trial shows that it strengthens follicles or slows hair loss.

learn Cetirizine

How does cetirizine reduce inflammation linked to hair loss? Cetirizine is proposed to lower prostaglandin D2 and raise prostaglandin E2 around hair follicles; three small trials of a compounded 1% topical report modest increases in hair density and shaft thickness, with minoxidil doing better head-to-head. Topical cetirizine is off-label and unapproved for hair loss, and the evidence is too thin to call it effective or safe.
