An interesting article, I have not deeply researched the topic, but I think I remember some guys talking about it for hair loss.


"
In these experiments, methylene blue outperformed the other three antioxidants, improving several age-related symptoms in cells from both healthy donors and progeria patients. The skin cells (fibroblasts, the cells that produce the structural protein collagen) experienced a decrease in damaging molecules known as reactive oxygen species, a reduced rate of cell death and an increase in the rate of cell division throughout the four-week treatment.


Cao and her colleagues tested methylene blue in fibroblasts from older donors (>80 years old) again for a period of four weeks. At the end of the treatment, the cells from older donors had experienced a range of improvements, including decreased expression of two genes commonly used as indicators of cellular aging: senescence-associated beta-galactosidase and p16."
