Morphological and Physical Changes in Hair Due to UV Irradiation

The conversation discusses concerns about RU58841 degrading when exposed to light and transferring pyri to a dark glass bottle to prevent this. The user keeps the pyri out for only two minutes before storing it in a dark place.

The user discusses their experience with diffuse unpatterned alopecia and acquired progressive hair kinkering, noting improvements with treatments including biotin, pantothenic acid, finasteride, ketoconazole, and zinc pyrithione shampoo. They report thicker, healthier hair and improved scalp condition, attributing success mainly to biotin, pantothenic acid, and finasteride.

Exosomes combined with fractional picosecond laser treatment were effective in treating androgenetic alopecia and promoting repigmentation in white hair patches. The role of exosomes in hair repigmentation, particularly in conditions like poliosis, is not well-studied.

Male-pattern baldness might increase UVB exposure on the scalp, potentially affecting vitamin D and skeletal health. The hypothesis is debated, with some seeing it as a minor benefit in specific contexts.

RU58841 may still be potent after being left unopened for four months if protected from light and air. A user reported hair improvement using RU58841 with minoxidil, without major shedding, over 2.5 years.

A user observed orange fluorescence on their nose and hair under a black light, indicating Cutibacterium acnes, which may contribute to hair loss alongside androgenic alopecia. A suggestion was made to use coal tar shampoo to address the issue.
