Efficacy of Intralesional Injection of Vitamin D3 in Treatment of Alopecia Areata

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.

Vitamin D supplementation can aid hair regrowth for some, but results differ. Combining vitamin D with finasteride and minoxidil often improves hair thickness, though not for everyone.

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 conversation discusses hair loss treatments, including oral finasteride, topical minoxidil, and microneedling, and the potential impact of Vitamin D and folic acid deficiencies on hair regrowth. It suggests that while male pattern baldness is the primary cause, addressing vitamin deficiencies may aid in improving regrowth.

The user is experiencing some hair regrowth after 3 months of using finasteride, minoxidil, biotin, vitamin C, and vitamin D, with noticeable improvements in hair thickness and baby hairs on the hairline. Other users suggest additional treatments like dermarolling and scalp massages for better results.

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).
