Vitamin D and Alopecia Areata: Possible Roles in Pathogenesis and Potential Implications for Therapy

The user is experiencing hair thinning and has a vitamin D deficiency, which they suspect might be causing the issue, but they are also considering androgenic alopecia (AGA) as a cause. They are currently using minoxidil and are unable to get finasteride prescribed, while others suggest addressing the vitamin D deficiency and consulting a dermatologist.

Topical Vitamin D3 may stimulate hair growth and has been used for Alopecia Areata. There is a question about the lack of research on its use for Androgenetic Alopecia (AGA).

Vitamin D deficiency is linked to hair loss, and supplementation with vitamin D can improve conditions like androgenic alopecia and telogen effluvium. Users discussed various dosages of vitamin D, emphasizing the importance of getting blood tests to determine the appropriate amount.

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.

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.

The user has been using oral finasteride for 15 months and oral minoxidil for 6 months, and developed alopecia areata, for which a dermatologist prescribed calcipotriol/betamethasone. The treatment is helping, but the user is experiencing another shedding phase and is concerned about the effects of the steroid cream and the cause of hair loss.
