Minireview: Vitamin D Receptor: New Assignments for an Already Busy Receptor

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.

Vitamin D may counteract DHT and help with hair growth, as seen in mice and human hair cultures. Some users discuss using Vitamin D, magnesium, and other supplements for hair health, while others humorously note the success in mice.

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.

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 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.

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.
