Did you mean Insulin-like Growth Factor 1?

GlossaryInsulin-like Growth Factor 1

hormone promoting cell growth and development, similar to insulin

Insulin-like Growth Factor 1 (IGF-1) is a hormone similar in structure to insulin that plays a crucial role in childhood growth and continues to have anabolic effects in adults. It is primarily produced in the liver and is stimulated by growth hormone (GH). IGF-1 is involved in cell growth, development, and repair, and has been studied for its potential effects on hair growth and the treatment of conditions like alopecia.

community Serum based on plant extracts boosts hair growth in weeks.

in Treatment 44 upvotes 9 months ago

A serum containing Centella asiatica extracellular vesicles, IGF-1, FGF-7, and caffeine significantly improved hair thickness, density, length, and reduced hair loss after 56 days. The conversation also discusses how treatments like finasteride, minoxidil, and ketoconazole address different aspects of hair loss by reducing DHT, improving blood flow, and lowering inflammation.

community Ultimate Stack without nuking your gender (you'll go broke)

in Treatment 86 upvotes 1 year ago

A hair loss treatment plan includes finasteride, dutasteride, RU58841, pyrilutamide, minoxidil, and microneedling to inhibit DHT and promote hair growth. It also recommends supplements like Reishi and Lion’s Mane mushrooms, and a shampoo with ketoconazole, caffeine, and melatonin.

community Looks like a real cure to the root of baldness (DHT-induced senescence) was proven earlier this year

in Research/Science 739 upvotes 3 years ago

A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.

community Is DHT actually the cause of male pattern hair loss or just a correlating factor? Why I think the research is more complicated than we're told and why I've been looking into GHK-Cu

in Research/Science 78 upvotes 2 months ago

DHT is not the only cause of male pattern hair loss; genetic sensitivity, inflammation, and fibrosis also contribute. GHK-Cu, a copper peptide, is being explored as an alternative treatment to finasteride and minoxidil, showing potential in improving follicle health.

community Female, 30, PCOS diagnosis, MPB Norwood 2. Endo refuses to give anything other than Spironolactone. Feel like I’m at my wit’s end here.

in Female 57 upvotes 2 years ago

A 30-year-old female with PCOS and male pattern baldness is frustrated with her endocrinologist's recommendation of only Spironolactone and minoxidil, feeling that dutasteride, finasteride, and progesterone would be more effective. Other users suggest various online sources for treatments, warn against self-medicating due to potential risks, and recommend seeking a specialized endocrinologist or considering additional treatments like Inositol, Berberine, and dermaneedling.
