Did you mean Keratinocyte Growth Factor?

GlossaryKeratinocyte Growth Factor

stimulates skin and hair cell growth and repair

Keratinocyte Growth Factor (KGF), also known as Fibroblast Growth Factor 7 (FGF-7), is a protein that plays a crucial role in the growth and repair of skin and hair. It specifically stimulates the proliferation and differentiation of keratinocytes, which are the primary cells found in the outer layer of the skin and hair follicles. This makes KGF important in wound healing and potentially beneficial in treating conditions like alopecia.

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

in Research/Science 370 upvotes 4 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 Weed/THC effects on hair growth/hair loss, and vitality of organ-culture human follicle studies (research review)

in Research/Science 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 Painkillers May Block Minoxidil

in Research/Science 14 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.

Most hair loss treatments are ineffective; only finasteride, dutasteride, and minoxidil show effectiveness.

community Minoxidil Response Bottlenecks: Why Sulfation and Transport Matter (And Where Tretinoin Fits In)

in Research 461 upvotes 1 year ago

Minoxidil's effectiveness is limited by the need for sulfation and proper transport to hair follicles, with tretinoin potentially enhancing its effects by promoting enzyme activity and keratinocyte differentiation. Tretinoin may improve minoxidil's response by boosting the expression of necessary enzymes and transporters.
