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

13 upvotes 3 years 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 Intermittent fasting reduces hair growth?!? :(

35 upvotes 1 year ago

Intermittent fasting may inhibit hair growth by triggering a stress response that affects hair-follicle stem cells. Some users believe genetics and DHT play a larger role in hair loss, and treatments like Minoxidil and Finasteride are mentioned as ineffective for some.

community Weed/THC effects on hair growth/hair loss, and vitality of organ-culture human follicle studies (research review)

4 upvotes 1 year ago

Cannabis and THC may have mixed effects on hair, with some studies suggesting potential negative impacts on hair growth in isolated hair follicles, but these results are hard to apply to living humans. Treatments like minoxidil and finasteride are commonly used for hair loss, and the effects of cannabis might be neutral or vary based on individual factors.

community The mechanism of androgenic alopecia

36 upvotes 11 months ago

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

community Painkillers May Block Minoxidil

12 upvotes 1 year ago

Painkillers like Aspirin may reduce Minoxidil's effectiveness by inhibiting the enzyme PGHS-1, which is crucial for hair growth. Using NSAIDs that inhibit COX-2 or combining Minoxidil with PGF2/E2 analogues or retinoids may enhance its efficacy.

learn Follistatin

glycoprotein that inhibits TGF-β and promotes hair growth by antagonizing activin

learn Ketoconazole

antifungal with some anti-androgenic benefits, often used as a shampoo

learn Metformin

diabetes drug with anti-inflammatory, immunomodulatory, and insulin-sensitizing properties

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.

learn Vascular Endothelial Growth Factor

What is Vascular Endothelial Growth Factor (VEGF), and how does it support hair growth in alopecia? VEGF promotes hair growth by enhancing blood supply to hair follicles.
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.
Is Vascular Endothelial Growth Factor (VEGF) available as a topical treatment, or is it only stimulated indirectly? VEGF is not available as a topical treatment for hair loss.
