Vitamin D Resistance: Tissue Resistance to Vitamin D and Vitamin D-Dependent Rickets Types I and II

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 can hinder hair recovery, and addressing it may help with hair loss. Hair loss may result from various issues like excess DHT, vitamin deficiency, or scalp inflammation.

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.

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.

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.
