A Case Control Study of Serum Vitamin D Levels in Alopecia Areata

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.

Vitamin D deficiency may contribute to hair loss, but correcting it alone doesn't guarantee regrowth. Users report mixed results with supplements and treatments like minoxidil, finasteride, and dutasteride.

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.

A 24-year-old male is experiencing hair loss due to low ferritin and vitamin D deficiency, and is using iron supplements, vitamin D3, finasteride, and ketoconazole shampoo for treatment. Users suggest increasing vitamin D and iron intake for better results and recommend consulting a professional for proper dosage.

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.
