Although there is no exact timeline for when these supplements may affect hair growth, researchers suggest that results can take up to three months. In one study, a woman diagnosed with diffuse hair loss caused by low serum vitamin D levels was recommended to take vitamin D supplements. So how quickly can vitamin D supplements work to stop hair loss? Available studies have shown that taking a vitamin D supplement for three months can decrease hair loss and stimulate hair growth from the follicles. When taking vitamin D dietary supplements for alopecia or hair loss, doctors should recommend the appropriate dose for daily vitamin intake and closely monitor the patient for results and any side effects.
The good news is that hair loss due to vitamin D deficiency is often reversible. Once vitamin D levels increase, hair follicles usually begin to work properly again and hair begins to grow back. It can take several months before new hair growth becomes visible, so be patient while you wait for results. Vitamin D deficiency is a treatable condition and, if it is the cause of hair loss, increasing levels can help stop or prevent further hair loss.
Hair loss is often a distressing experience, but you should know that you are not alone and that there are many treatment options you can explore. But if you're worried about hair loss, there are other things you can do to prevent it, such as reducing stress and using gentle hair care products. Dermatologists may prescribe vitamin D supplements to treat hair loss in different ways. Hair loss is not always caused by vitamin deficiencies and requires proper diagnosis to determine the best treatment to promote hair growth.
Another study was similarly successful, and researchers found that topical vitamin D treatment was effective for hair loss in nearly 70% of study participants. That said, she says the three most common types of hair loss are telogen effluvium (mentioned above), alopecia areata (also mentioned above), and trichotillomania. A lack of vitamin D in the body could also mean that there won't be enough keratin to stimulate hair growth and control thinning and hair loss. It is generally believed that the longer a person is deficient in vitamin D, the more likely they are to suffer from hair loss.
While vitamin D deficiency is linked to hair loss, it's not likely to be the cause of loss for most people who suffer from hair loss. Since many things could be at stake, Green says the best way to treat hair loss is to start by finding the underlying problem that is causing it. Vitamin D supplements may work best for hair restoration when taken in conjunction with appropriate treatments for hair loss. In addition to the most common causes of hair loss, Green says that living in a physically toxic environment can also lead to loss.
Some people may experience hair loss within a few months of vitamin D deficiency, while others may not see any effect for up to a year. It is generally believed that hair loss will slow down once it recovers its levels to a normal level.
