Some young people start to lose their hair and become bald at a young age, and they are distressed by hair loss, and their condition continues to worsen because of their ideological distress. The main cause of hair loss: the symptoms of hair loss are external, and the root is external, that is, internal diseases are external. The main reason is that the heat toxin in human blood can not be discharged, thus causing some diseases in human body. Hair follicle atrophy, hair falling off, easy to break, oil inelastic, and more serious cases are general shedding and total shedding. Hospital experts who treat alopecia in Beijing said that daily prevention should be paid attention to at the same time of treatment to prevent alopecia: 1, reasonable diet: Hair loss and gray hair are mostly caused by insufficient blood and nutrition, so you can eat more foods rich in iron, calcium and vitamin A and nourishing your hair, such as milk, poultry, vegetables, fish, lean meat and fruit with very high protein content. 2. Shampoo: Shampoo can remove dust and stop 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 use high-quality shampoo (water), and it is not advisable to use a shampoo with strong degreasing. When shampooing, you should massage while rubbing. After washing, pat your hair with a thick towel to absorb the remaining water, and it is best to let your hair dry naturally. 3. Comb your hair: comb your hair 10 times a day in the morning, at noon and at night. You can massage your scalp while combing to enhance the blood supply at the root of your hair and the nutrition of your hair.
