GlossaryPlatelet-Derived Growth Factor AA (PDGF-AA)

stimulates cell growth and tissue repair, including hair follicles

Platelet-Derived Growth Factor AA (PDGF-AA) is a protein that plays a crucial role in cell growth, healing, and development. It is one of the isoforms of PDGF, which are important for stimulating the proliferation and differentiation of cells, particularly in the context of wound healing and tissue repair. In the realm of hair biology, PDGF-AA can influence hair follicle development and regeneration, making it a potential target for treatments related to hair loss and alopecia.

community Surprisingly thorough study on He-Shou-Wu/Fo Ti

in Research/Science 14 upvotes 1 year ago

He Shou Wu (Fo Ti) extract was found to prolong the hair growth phase, inhibit 5-alpha-reductase (like finasteride), reduce androgen receptors, and increase growth factors, potentially outperforming minoxidil in recovering hair follicle size after DHT exposure. Two compounds, emodin and TSG, are identified as responsible for these effects and warrant further investigation.

community Seriously confused about minoxidil's method of action

in Minoxidil 6 upvotes 2 years ago

The conversation discusses confusion about how Minoxidil promotes hair growth compared to other substances like Menthol, which have similar actions. The user mentions personal positive results with peppermint oil extract and is currently trying L-citrulline for its vasodilation effects.

community 2 years later I managed to gain some ground (Hyperresponder)

in Progress Pictures 43 upvotes 1 year ago

The user regained most of their hair using Minoxidil, Finasteride, and Dermarolling. They found Dermarolling particularly effective, as it promotes growth factors and improves hair thickness.

community Comprehensive Microneedling Guide
