Glossary Insulin-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.

44 upvotes 11 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 Whey Protein can cause hairloss in men with AGA as per a doctor

64 upvotes 9 months ago

Whey protein may slightly increase hair loss in men with androgenetic alopecia (AGA) due to elevated IGF-1 and testosterone levels, but the effect is minimal compared to treatments like finasteride and dutasteride. Many users argue that whey protein's impact on hair loss is negligible and that maintaining a healthy lifestyle is more important.

community Ray Peat: Testosterone Isn’t the Culprit, Prolactin and Cortisol Drive Hair Loss (2016)

in Research/Science 110 upvotes 11 months ago

Prolactin and cortisol are identified as key factors in hair loss, with stress hormones impacting hair shedding. Finasteride and minoxidil are effective treatments, while DHT's role and individual sensitivity are significant factors.

community Creatine is the opposite of minoxidil !

324 upvotes 11 months ago

Creatine may counteract minoxidil's hair growth effects by closing potassium ATP channels, potentially leading to hair loss in predisposed individuals. Despite anecdotal reports, there is no conclusive evidence linking creatine to hair loss.

community Wtf have we been doing for the last 30 years

in Treatment 548 upvotes 1 year ago

Hair loss treatments like finasteride, minoxidil, and dutasteride work but have side effects. A permanent cure is still not available due to the complexity of hair loss and limited investment.
