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 user treated androgenic alopecia with topical minoxidil, finasteride, vitamin D, and biotin, while also using ketoconazole shampoo for dandruff. They focus on weight training and take daily vitamin D tablets.

Low vitamin D levels can negatively impact hair growth, and supplementing with vitamin D, along with treatments like finasteride and minoxidil, may help improve hair health. Quitting smoking and ensuring adequate vitamin B12 and K2 intake are also suggested to support hair regrowth.

The user experiences increased hair loss in winter, possibly due to lack of sun and vitamin D, and is using finasteride and vitamin D3 supplements to address it. Suggestions include using a red light lamp and maintaining vitamin D intake.

A user with diffused thinning hair has been using topical minoxidil for over three years with little improvement and is now taking finasteride regularly. They were found to be vitamin D deficient and are on a 20,000 IU weekly prescription, seeking advice on whether correcting the deficiency can aid hair regrowth.

A 21-year-old male diagnosed with telogen effluvium and male pattern baldness started oral finasteride, which initially slowed hair loss and slightly thickened hair, but experienced increased shedding after surgery. The doctor recommended iron and vitamin D supplements, and the user is seeking additional advice.
