What causes yellow hair?

If your hair is dry and yellow, it may be due to your physical constitution. Especially for people with acidic constitution, they are most likely to have dry and yellow hair. In addition, if you lack certain nutrients, such as copper, or have malnutrition, it may also cause dry and yellow hair.

Reason 1: Acidic body

An acidic constitution may also cause dry and yellow hair. An acidic constitution is a condition in which there is an increase in acidic toxins in the blood. This may be caused by excessive fatigue, or it may be related to eating too much sweets or fat. In this case, you should eat more foods that can neutralize the acidic toxins in the body, such as fresh vegetables and fruits, including celery, spinach, rapeseed, Chinese cabbage and citrus, as well as kelp, fresh milk, fish, beans and mushrooms, which can also effectively improve the dry and yellow hair caused by acidic constitution.

Reason 2: Functional yellow hair

Functional yellow hair mainly refers to the disorder of melaninogen and melanocyte production in the body due to mental trauma, seasonal endocrine disorders, fatigue, drugs and chemical stimulation, resulting in dry and yellow hair. At this time, it is necessary to eliminate these abnormal conditions and improve them by eating more black sesame seeds, sea fish and alfalfa.

Reason 3, copper deficiency

If the body lacks copper, it will affect the activity of "tyrosinase", which is an important substance required for the production of melanin in hair, and it requires copper. Therefore, it is necessary for us to supplement copper-containing elements appropriately. Foods such as animal liver, potatoes, tomatoes, celery and some fruits are rich in copper.

Reason 4: High level of malnutrition

When the body is severely malnourished, it is easy for the hair to become dry, yellow and dull, so it is necessary to pay attention to adjusting the diet and improving the body's nutritional status. You can eat more eggs, soybeans, lean meat, walnuts, peanuts, and black sesame seeds. In addition to containing a large amount of animal protein and plant protein, they also contain cystine and cysteine, which are the main components of hair, and are the best foods for hair care.
