In this study, female androgenic alopecia (grade II or III on Ludwig's scale) was found to be common among Finnish women aged 63, and several markers of insulin resistance, along with paternal history of alopecia, were associated with an increased risk.
This study found that hair dyed with anionic basic hair dye lost more color after shampooing compared to cationic and nonionic dyes, with alkaline shampoo increasing this effect.
Researchers are working on regenerating hair follicles using stem cells, but a cure for baldness is still years away. Current treatments mentioned include Minoxidil, finasteride, and RU58841.
Insulin resistance may increase DHT production, contributing to hair loss, and addressing it through diet, nutrients, and natural DHT blockers like saw palmetto and pumpkin seed oil could help reverse hair loss. Some users prefer medications like finasteride for more effective results.
Transplanting pubic and butt hair to the head is discussed humorously, highlighting pros like DHT resistance and cons like poor blending and appearance. Users joke about using treatments like Minoxidil, Finasteride, and RU58841 on unconventional donor areas.
A medical student experienced hair loss slowing with Finasteride but developed severe, treatment-resistant insomnia. They tried various medications with little effect, suspecting Post-Finasteride Syndrome, and others suggested the insomnia might be linked to Finasteride's impact on neurosteroids.
A 57-year-old man with male pattern hair loss and insulin resistance experienced hair regrowth and weight loss after using tirzepatide, without other hair treatments. Dysregulated glucose metabolism is linked to hair loss, with tirzepatide potentially improving hair density by normalizing insulin resistance.
Hair transplantation moves DHT-resistant follicles from a donor area (back and sides of the scalp) into thinning or bald areas. The transplanted hair is generally permanent, though surrounding native hair can keep thinning.
