Collagen or biotin? Experts explain

With the increasing popularity of hair care supplements, collagen and biotin are emerging as the most popular options among those looking for thicker, stronger hair. However, experts and scientific research indicate that the effectiveness of each varies according to the causes of hair problems and the individual’s health condition.

Biotin, known as vitamin B7, is an important component in the production of keratin, which is the basic protein that makes up hair. Studies show that biotin deficiency may lead to weak hair and hair loss, but this deficiency is rare in people who follow a balanced diet.

As for collagen, which is the most abundant protein in the body, it plays an indirect role in supporting hair health by providing the amino acids necessary to build proteins, in addition to its contribution to maintaining the health of the skin and scalp.

Research suggests that biotin may be more beneficial for people who are already deficient in the vitamin, while collagen may help support scalp health and combat some of the effects of aging associated with hair follicles.

Specialists confirm that hair health does not depend on a single nutritional supplement, but rather is linked to multiple factors, including balanced nutrition and obtaining sufficient amounts of protein, iron, zinc and vitamin D, in addition to good sleep and reducing stress.

Experts also warn against believing that supplements alone are capable of treating all hair problems, pointing out that some cases of hair loss may be linked to health reasons such as thyroid disorders, anemia, or hormonal changes, which requires an appropriate medical diagnosis.

According to specialists, the best results for maintaining healthy and strong hair are achieved by treating the underlying causes of the problem and following a healthy lifestyle, rather than relying on nutritional supplements alone.
