This study found cutaneous keratinic amyloid deposition in dogs and identified cytokeratin 5 as an amyloid precursor protein, revealing new insights into the etiology of cutaneous amyloidosis.
Hairfollicles are mostly dormant but can be reactivated with treatments like minoxidil, finasteride, and microneedling. A new drug, PP405, shows promise for hair regrowth but may not be available until 2027-2028.
Hairfollicle cloning is claimed to be possible but not widely available due to potential safety issues, such as cancer risks. Current treatments like finasteride and dutasteride are not effective for everyone, and there is frustration over limited access to these medications.
PP405 is a promising molecule that may reactivate dormant hairfollicles, potentially offering a new treatment for hair loss. It is in phase 2 trials, with possible availability between 2027 and 2030.
PP405, developed by Pelage Pharmaceuticals, can reactivate dormant hairfollicle stem cells and increase hair growth by 20% in eight weeks, unlike minoxidil or finasteride. However, skepticism remains about its effectiveness and availability, with concerns about funding and the timeline for broader access.
Hairfollicles often go dormant rather than die, and treatments like minoxidil can help revive them. Scalp health and stimulation, such as massages and using products like sulphur soap, are also important for hair regrowth.
