Methods to prevent alopecia:

1, eat food containing protein.

Daily intake of protein is hair tonic. Excellent protein includes fresh fish, meat, eggs, bean products, milk and so on. These foods are rich in protein, which can be digested and absorbed by gastrointestinal tract to form various amino acids. After entering the blood, it is absorbed by dermal papillae at the root of hair to synthesize keratin. After keratinization, it is our hair. This process fully shows that protein is the foundation of hair.

Step 2 eat foods containing vitamins

Hair loss and dandruff are common symptoms of vitamin A deficiency. Carrots, spinach, lettuce leaves, almonds, nuts, mangoes and other fruits and vegetables contain more vitamin A, and so do animal livers, fish, shrimps and eggs. Vitamin B can promote scalp metabolism and generally exists in fresh fruits and vegetables and whole grains. The normal secretion of oil by sebaceous glands depends on the adequate intake of vitamin C. At the same time, vitamin C can activate the microvascular wall and make the hair roots absorb nutrients in the blood smoothly.

3. Eat foods containing trace elements

Copper and iron in trace elements also play an important role in maintaining hair health. Lack of copper will cause hair to fade. Iron plays an important role in ensuring the oxygen content in the blood delivered to the hair. Green vegetable food is rich in alkaline inorganic salts (calcium, magnesium, sodium, potassium, etc. ), can neutralize the acidic substances that are not conducive to hair growth in the body and make them become non-toxic. White hair or hair loss can be embarrassing. Maybe you've tried everything to no avail. You'd better eat more foods containing zinc.

Step 4 comb your hair often

Comb your hair 10 times a day. You can massage your scalp while combing your hair to enhance the blood supply of your hair roots and the nutrition of your hair. It is best to use a wooden comb or horn comb when combing your hair. Don't comb your hair when it is wet, so as not to damage it.

5. Wash your hair often

Shampooing can remove dust and relieve itching, which is beneficial to the breathing of the head skin. It is advisable to wash your hair 4-7 times a week. It is best not to wash your hair with too hot water. Shampoo products should choose high-quality shampoo (water), and it is not advisable to use shampoo with strong degreasing. Rub and massage when washing your hair. After washing, pat your hair with a thick towel to absorb the residual moisture. It's best to let your hair dry naturally.
