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 using tretinoin for hair loss and whether applying SPF on the scalp is necessary if hair covers the treated areas. The user is considering this treatment despite having no completely bald patches.

The user shaved their head and noticed darker areas on the scalp despite using finasteride, minoxidil, and microneedling. Other users suggest the darkness might be due to bruising or scarring from microneedling and recommend switching to dutasteride.

The user is using topical minoxidil and finasteride, along with daily derma rolling, and is considering using an organic self-tanner on their shaved scalp. They seek advice on whether the self-tanner's ingredients could harm hair regrowth.
