Vitamin D and Its Analogs in Treatment of Mild to Moderate Alopecia Areata: Systematic Review and Meta-Analysis

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).

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.

Vitamin D3's impact on hair loss is debated, with some users suggesting it may not significantly help. It's recommended to check vitamin D levels and consult a doctor for appropriate dosage, while treatments like finasteride are considered more effective for hair loss.

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 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.
