Association Between Vitamin D Deficiency and Psoriasis: A Case-Control Study

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.

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.

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 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 supplementation can aid hair regrowth for some, but results differ. Combining vitamin D with finasteride and minoxidil often improves hair thickness, though not for everyone.

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.
