Impact of Ultraviolet Radiation-Induced Damage to Hair Fiber Integrity: A Multi-Technique Physicochemical Characterization of Surface and Cortex Properties

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.

The conversation discusses whether sunlight exposure affects hair growth or loss, with mixed anecdotes and theories but no clear consensus. Some suggest moderate sunlight can benefit hair by providing vitamin D, while others doubt its effectiveness compared to treatments like Minoxidil or finasteride.

The conversation discusses hair loss struggles and treatments, including oral minoxidil, oral finasteride, and RU58841. Users share experiences and advice, suggesting options like topical minoxidil, microneedling, hair transplants, and scalp micropigmentation.

High frequency ultrasonography and HR-MRI can help identify hair shedding causes like inflammation and fibrosis. The conversation discusses the potential of using these technologies to evaluate treatments like Verteporfin for hair regeneration.

PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.

Selenium sulfide shampoo helped with a sore scalp but may cause hair root damage. Users experienced hair loss with selenium sulfide and ketoconazole, suggesting reducing use if hair loss occurs.
