community Scalp slapping to increase blood flow?

in Treatment 22 upvotes 2 years ago

This post and conversation are about using scalp slapping to increase blood flow for hair growth. One user suggests using minoxidil instead.

community Why does MPB only affect the scalp

in Research/Science 14 upvotes 1 year ago

Male pattern baldness (MPB) may be influenced by androgen receptors in scalp hair follicles and potentially poor blood flow. Transplanted hair is not immune to DHT, and factors like inflammation and scalp tension might also contribute to hair loss.

community Why does the same hormone grow your beard and destroy your hairline?

44 upvotes 4 months ago

DHT promotes beard growth but causes scalp hair loss due to inflammation and fibrosis. Treatments like finasteride and minoxidil help with hormonal signals and blood flow but don't address underlying inflammation.

learn Vascular Endothelial Growth Factor

Can products that stimulate Vascular Endothelial Growth Factor (VEGF) improve blood flow to hair follicles? Yes, products that stimulate VEGF may improve blood flow to hair follicles.

learn Centella

Ever wonder why your hair doesn’t grow back thick anymore? Maybe your scalp needs better blood flow: centella could help. There is no clinical trial of centella asiatica for hair loss and no study measuring scalp blood flow in people using it; the only hair-related evidence is a 2017 cell-culture study. Centella products are cosmetics that may soothe an irritated scalp, and the link between scalp circulation and pattern hair loss is itself unproven.

learn Botox

Could Botox be the unexpected solution for chronic hair shedding? Botox may help reduce chronic hair shedding by improving scalp blood flow.

learn capsicum

Can the heat from capsicum actually wake up dormant hair follicles? Capsicum heat may stimulate dormant hair follicles through increased blood flow and growth factors.
How does capsicum improve scalp circulation and boost growth? Capsaicin dilates blood vessels through TRPV1 activation, so capsicum is expected to raise scalp blood flow, but every human hair-loss study used it inside a multi-ingredient formula — and the strongest one gave it orally, not on the scalp — so its effect on hair by itself is unproven, and it is a known skin irritant.
