What are hair growth vitamins and do they actually work?
Hair growth is very complicated, dependent on each individual’s situation, and often requires a multimodal approach. According to Dr. Gordon, “[The best vitamins for hair growth] are definitely helpful, and if you are deficient in any of the amino acids, omega acids, or other vitamins, then they are necessary to provide you with the building blocks to grow hair.” She continues, many hair growth gummies and capsules also contain plant extracts and other natural ingredients that can mimic some pharmaceutical hair growth medications as well as provide novel mechanisms for hair growth. Some can also help with hormonal changes, stress, and other ailments.
However, as Vitti explains, taking more micronutrients doesn’t always lead to more hair growth for two main reasons: first, the body gets rid of what it can’t use, and second, people with gut issues might have trouble absorbing nutrients properly. Plus, results can take a long time—think three to six months to notice any real change. It’s also so difficult to be stuck in the cycle of stress and hair loss (which causes more stress), so make sure you look at your overall wellness and health if you choose to add these vitamins into your diet.
