Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hairfollicles. There's also a change in gene expression related to blood vessels and cell growth in balding hairfollicles. The exact molecular causes of AGA are still unclear.
Androgenetic alopecia is caused by DHT affecting hair growth. Finasteride and minoxidil are used to manage hair loss by blocking DHT and promoting hair growth.
IGFBP‐rP1 shows potential for treating androgenic alopecia by influencing hair cycle transitions. Increasing IGF-1 levels may have similar effects to Minoxidil and 5-AR inhibitors in reducing hair loss.
A topical solution called "Multi-Peptide Serum for Hair Density" by The Ordinary Company, which contains several ingredients that are used in alternatives to Minoxidil and was found to have better results than 5% Minoxidil in a study. People who have tried it shared their experiences with the serum as well.
A potential treatment for hair loss that involves injecting fat into the scalp; the role of testosterone and estrogen in thinning fat tissue under the skin; research on using lard to treat androgenic alopecia, as well as PRP + ACELL/amniotic stem cell treatments; and ongoing clinical trials by doctors involved in the study.
