Effect of Vitamin A on the Growth of Hair and Nails

Vitamins and minerals like vitamin E, zinc, and iron may aid hair growth, especially in cases of deficiency. Pumpkin seed oil, saw palmetto, horsetail, and AminoMar show some promise for improving hair health and count.

Low vitamin D levels can negatively impact hair growth, and supplementing with vitamin D, along with treatments like finasteride and minoxidil, may help improve hair health. Quitting smoking and ensuring adequate vitamin B12 and K2 intake are also suggested to support hair regrowth.

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.

A user experienced significant hair regrowth after improving their diet, getting sunlight, taking a multivitamin, and exercising, following a period of extreme calorie restriction and hair shedding. Others in the conversation attribute the hair regrowth to increased calorie intake rather than just vitamins.

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.

The conversation discusses using topical vitamin C in shampoo or serum for hair growth and thickness. The user mentions using the Nioxin system to maintain thick hair and is curious about the effects of vitamin C on hair growth.
