If you don’t grow a beard at the age of 21, it will still be fluffy

It is mostly normal for 21-year-old men to have no beard or only have villi, which may be related to factors such as genetics, hormone levels, and delayed hair follicle development. In a few cases, pathological factors such as endocrine diseases or malnutrition need to be considered.

Male beard development is significantly affected by genetic genes. If family members have delayed beard growth, the individual may have a similar situation. When testosterone levels are insufficient or when hair follicles are less sensitive to androgens, beards may appear thin and downy. It usually takes several years for hair follicles to fully mature after puberty, and it is more common for hair follicles to still be in the developmental stage by the age of 21. Daily high-quality protein and zinc can be supplemented appropriately, such as beef, oysters and other foods to avoid excessive anxiety.

Endocrine diseases such as hypothyroidism and pituitary dysfunction may be accompanied by symptoms such as sparse body hair, fatigue and cold sensitivity. Long-term dieting or lack of B vitamins may cause hair growth to be blocked. Such situations need to be confirmed by professional examination. If you also have symptoms of delayed development of secondary sex characteristics such as an unclear Adam's apple and a high-pitched voice, it is recommended to get your sex hormone levels checked by a doctor as soon as possible.

Maintaining a regular sleep schedule and moderate exercise can help maintain normal hormone secretion, and avoid using hair removal products or harsh chemicals on the face. It is not recommended to take hormone drugs by yourself. Improper supplementation may interfere with endocrine balance. If there is still no significant beard growth after the age of 25, you can go to an endocrinologist or andrology department for a systematic evaluation.
