Does Vitamin D Help Prevent Hair Loss?

It is well known that vitamin D can help thicken existing hair, according to Levitan. But can it help with hair loss? The answer depends on whether the hair loss is due to a vitamin D deficiency. Chacón suggests that a laboratory analysis of hair loss should include tests to assess current levels of vitamin D. Vitamin D supplements are said to help with alopecia and baldness, but only to a certain extent.

Low levels of vitamin D may be associated with a poor hair growth cycle, which can lead to slow growth and thinning of the hair, as well as the appearance of bald spots. Fortunately, hair loss due to vitamin D deficiency is often reversible. Once vitamin D levels are increased, the hair follicles will normally begin to function properly and the hair will begin to grow again. It may take several months for new hair growth to become visible, so patience is key.

Vitamin D supplementation is a good solution for restoring ideal hair health, but it may not be sufficient to treat symptoms of serious hair loss problems. To get to the root of the problem, Green recommends finding the underlying cause of the hair loss. Studies have shown that taking a vitamin D supplement for three months can reduce hair loss and stimulate hair growth from the follicles. Your doctor can test you for vitamin deficiencies and other conditions that may be causing hair loss.

Prolactin has been linked to hair loss, and high levels of this hormone can interfere with the normal hair growth cycle. One study found that women with vitamin D deficiency were more likely to suffer from hair loss than women who had sufficient levels of vitamin D. If you're losing your hair and don't know why, see your doctor to find out the cause and get treatment. Vitamin D supplementation is a good solution for restoring ideal hair health, but it may not be sufficient to treat symptoms of serious hair loss problems.
