Glossary Dermal Papilla Fibroblasts

specialized cells at hair follicle base aiding hair growth

Dermal Papilla Fibroblasts are specialized cells located at the base of hair follicles. They play a crucial role in hair growth and regeneration by interacting with other cells to regulate the hair cycle and provide essential signals for hair follicle development.

community New Hair Loss Cure: AMP-303 Is Back. It’s what PP405 should have been.

7 upvotes 5 months ago

AMP-303 and AMP-601 are new hair loss treatments targeting dermal papilla cells, with AMP-303 showing early efficacy in transitioning vellus hairs to terminal hairs after one injection. Further clinical trials are planned, and these treatments are seen as promising due to their biologic approach and less frequent application compared to daily treatments.

community Reducing Fibrosis in Hair Loss: Topical Pirfenidone

59 upvotes 5 months ago

Topical pirfenidone is highlighted as an effective anti-inflammatory and anti-fibrotic treatment for hair loss, particularly in addressing perifollicular fibrosis, which may enhance the effectiveness of standard treatments like finasteride and minoxidil. The user also uses calcipotriol, MCT oil, ciclopirox shampoo, and benzoyl peroxide shampoo as part of their regimen.

community Hair Multiplication Projects in China - Promising clinical trial results on Mice

34 upvotes 1 year ago

A breakthrough in hair follicle cultivation using induced pluripotent stem cells (iPSCs) has been achieved, producing large hair follicles suitable for transplantation. Clinical trials for this hair multiplication technology are planned in partnership with Yinguan Biotechnology.

community DHT Isn’t the Only Factor in Hair Loss and That Might Be the Key to a Real Cure

373 upvotes 6 months ago

Hair loss involves more than just DHT, with genetic factors like TRPS affecting hair follicles. Treatments such as Amplifica's AMP-601 and AMP-303 target stem cells for potential hair growth solutions.

community Got my Oleic fatty acid they used in Korean study. Fuck you mice!

247 upvotes 7 months ago

Oleic acid and microneedling are being explored for hair regrowth, but results are mixed. Addressing DHT and fibrosis is crucial, with treatments like finasteride, minoxidil, and scalp massage also discussed.

learn SCUBE3

a signaling molecule from dermal papilla cells being actively researched

How does SCUBE3 work on hair follicles compared to treatments like minoxidil or finasteride? Laboratory research in mice reports that SCUBE3, a protein released by dermal papilla cells, signals dormant follicles to grow through the TGF-β pathway downstream of Hedgehog; minoxidil and finasteride instead work on blood flow to the follicle and on DHT, and unlike SCUBE3 they have decades of human trial data behind them. SCUBE3 has not been tested in human clinical trials and is not available as a medicine.

learn Platelet-Rich Plasma

What is Platelet-Derived Growth Factor Beta Polypeptide, and how does it help stimulate new hair growth? PDGF-BB is a growth factor that signals to dermal papilla cells and promotes blood-vessel formation; mouse studies report it can push follicles into the growth phase, and human evidence comes only indirectly from PRP trials. No PDGF product is approved for hair restoration and there is no published human trial of PDGF-BB on its own.
