Vitamin D Levels and Their Relationship with the Type of Involvement in Alopecia Areata Patients

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 19-year-old female with Diffuse Alopecia was advised by a dermatologist to use vitamin supplements, a hair serum, and antifungal drops, leading to some improvement. Other users suggested treatments like minoxidil, microneedling, and consulting a different dermatologist for further advice.

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.

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).

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.
