Vitamin D and Skin: A Review and Update

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.

The conversation discusses hair shedding potentially linked to vitamin D supplementation after Accutane use, with the user suspecting telogen effluvium. Others suggest the hair loss might not be related to vitamin D, considering it a coincidence.

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.

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).

Vitamin D tests like D2, D3, and 25-hydroxyvitamin D are discussed before starting hair treatment. Vitamin D can be obtained from food, but overdose has side effects.
