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 Bloodflow? Does it affect hair growth?

23 upvotes 7 years ago

Hair loss is primarily caused by genetic sensitivity to DHT, not lifestyle factors like diet or exercise. Treatments like Minoxidil and Finasteride can help, but it's important to consult a dermatologist to determine the best approach for individual cases.
