Predictors of Vitamin D Insufficiency in Children and Adolescents With 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.

The user experiences increased hair loss in winter, possibly due to lack of sun and vitamin D, and is using finasteride and vitamin D3 supplements to address it. Suggestions include using a red light lamp and maintaining vitamin D intake.

An 18-year-old with diffuse hair thinning is considering switching from a topical Minoxidil 10% + Finasteride 0.1% solution to Minoxidil 5% foam and oral Finasteride 0.5mg, while also addressing vitamin D deficiency and potential scalp inflammation. Users suggest using Nizoral shampoo for inflammation, considering dutasteride for better results, and maintaining vitamin D levels to protect hair follicles from DHT.

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 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.
