Rickets and Alopecia with Resistance to 1,25-Dihydroxyvitamin D: Two Different Clinical Courses with Two Different Cellular Defects

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.

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 supplementation may have led to slight hair regrowth and density improvement. Other treatments discussed include finasteride, minoxidil, and maintaining optimal vitamin D levels.

Vitamin D3's impact on hair loss is debated, with some users suggesting it may not significantly help. It's recommended to check vitamin D levels and consult a doctor for appropriate dosage, while treatments like finasteride are considered more effective for hair loss.

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 user has androgenetic alopecia (AGA) and low Vitamin D levels, and they started using topical minoxidil (5%). They are considering finasteride but are concerned about side effects and are advised to seek mental health support.
