Can the shampoos and serums marketed today claiming to contain biotin make hair grow?
Unfortunately, at this time, research shows that there is no evidence that biotin in hair products can make hair grow because the biotin contained in these products likely cannot penetrate the skin.
But the good news is Biotin supplements could be helpful for a person who wants to regrow lost hair. When a person takes biotin supplements, the nutrient is entering the body directly. If there is any benefit to be had from the use of biotin for hair regrowth, biotin supplements may be the best way for a person to take advantage of them. In addition to the hair, biotin may also improve the appearance of the skin and help boost a person’s metabolism.
Hair loss can be a symptom of a biotin deficiency, so taking biotin supplements may help relieve this problem. Biotin is a B vitamin found in a variety of foods, including eggs, bananas, and salmon. This vitamin strengthens cells and aids the metabolism. Healthy cells and a properly functioning metabolism contribute to hair growth and restoration.
Consult with your doctor if biotin supplementation is right for you and which strength of biotin supplement is appropriate for your needs.
