Treatment of Alopecia Totalis, Universalis, and Focalis with Vitamin D and Analogs: Three Case Reports and a Literature Review

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.

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.

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.

Vitamin D supplementation may have led to slight hair regrowth and density improvement. Other treatments discussed include finasteride, minoxidil, and maintaining optimal vitamin D levels.

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.

A 25-year-old experiencing hair thinning all over the body and head, despite using minoxidil and having low vitamin D levels, is advised to seek a second opinion from a dermatologist specializing in hair loss. The likely diagnosis is diffuse alopecia areata, which may require treatment with a JAK inhibitor.
