TLDR IGF-1 may affect hair growth and loss, but more research is needed to confirm effective and safe treatments.

The 2017 document provides clinical evidence that insulin-like growth factor 1 (IGF-1) plays a role in hair growth and alopecia, discussing three patients with hair loss issues and GH/IGF-1 deficiency. It also notes that low IGF-1 levels are linked to hair loss in middle-aged women and that treatments like Platelet-rich plasma (PRP), which contains IGF-1, are being used despite limited clinical validation. A study on hamsters indicated that hair grew faster and thicker with a 3% liposomal IGF-1 and VEGF solution. However, the document concludes that more research is needed to fully understand the efficacy, safety, and cost-effectiveness of GH and IGF-1 treatments for hair loss.

community Diffuse hair loss and scalp biopsies

in Research 692 upvotes 3 months ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
