What's wrong with the yellow beard?

Beards, like hair and pubic hair, are normal hair on the human body and play a role in regulating body temperature and protecting against cold and sun. Normal people's beards are usually black, but they will gradually turn white with age, which is a very normal phenomenon. However, many people have yellow beards. Patients with such symptoms often feel worried, fearing that it is a reaction to physical illness. So what is the reason for yellow beards?

Beard, commonly known as beard, refers to the hair growing on the upper lip, chin, cheeks, cheeks or neck of men. If you want to distinguish carefully, "胡" originally refers to the hair growing around the mouth, and the upper lip is called "髭" (moustache, also known as "八字胡", "八字须", "两撇雞", and "二撇雞" in Cantonese), the chin is called "羊胡" (goatee beard), the temples connected to the chin are called "落面胡" (also known as "絡面胡", "连须胡子"), the cheeks are called "髯", and the curly ones are called "陬髯".

Men after puberty generally grow beards. Beards grow faster than hair, which is the result of the action of male hormones. The more vigorous the reproductive function, the faster the beard grows.

There are more blood vessels there than at the roots of hair, and nutrients are easier to obtain, so after shaving your beard, it will grow back in a few days.

There are several reasons why your beard turns yellow:

1. Congenital heredity. If the elders in the family have this trait, the offspring may also have it. There is no solution to this.

2. Copper deficiency in the body: In the process of hair melanin production, an important enzyme called "tyrosinase" containing copper is lacking. Copper deficiency in the body will affect the activity of this enzyme, causing hair to turn yellow. Foods rich in copper include animal liver, tomatoes, potatoes, celery, fruits, etc.

3. Functionality: The main reasons are mental trauma, fatigue, seasonal endocrine disorders, drug and chemical stimulation, etc., which lead to the production disorder of melaninogen and melanocytes in the body. For this kind of yellow hair, you should eat more marine fish, black sesame, alfalfa, etc. The active ingredients in alfalfa can replicate melanocytes and have the function of regenerating melanin; black sesame can biochemically produce melaninogen; niacin in marine fish can dilate capillaries, enhance microcirculation, make qi and blood flow smoothly, eliminate the production disorder of melanin, and remove the yellow hair.

4. Pathogenicity: Due to certain diseases, such as iron deficiency anemia, hypothyroidism, severe malnutrition, severe iron deficiency anemia and recovery from a serious illness, the melanin in the body decreases, resulting in a lack of the basic substance of black hair, which gradually turns to yellow-brown or light yellow. In this case, you should eat more black beans, walnut kernels, fennel, etc. Black beans contain melanin production substances, which can promote the production of melanin. Anisole in fennel helps to convert melanogens into melanocytes, thereby making the hair dark and shiny.
