Serum 25 Hydroxyvitamin D in Non-Scarring Alopecia: A Systematic Review and Meta-Analysis

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.

A 25-year-old male experienced significant hair loss due to telogen effluvium and androgenetic alopecia. He began using finasteride, minoxidil, and vitamins, seeing some regrowth but remains worried about hair density.

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 35-year-old with alopecia areata has tried finasteride, topical and oral minoxidil, and dutasteride without success in stopping hair loss. The dermatologist suggests JAK inhibitors, but they are too costly, leading to uncertainty about the cause of hair loss.

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.

A 25-year-old experiencing hair thinning all over the body and head, despite using minoxidil and having low vitamin D levels, is advised to seek a second opinion from a dermatologist specializing in hair loss. The likely diagnosis is diffuse alopecia areata, which may require treatment with a JAK inhibitor.
