Hair Follicle Expression of 1,25-Dihydroxyvitamin D3 Receptors During the Murine Hair Cycle

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

The conversation is about a user experiencing accelerated hair loss after starting vitamin D3 supplements, suspecting a link between the supplement and increased DHT levels. The user decides to stop taking the supplements, preferring natural sources of vitamin D.

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.
