1. About hair loss: Hair growth is cyclical and can be divided into growth phase, regression phase and resting phase. Generally speaking, the average person has about 100,000 hairs, and 50 to 100 hairs fall out every day, so don't be too nervous if you see hair loss every day, as long as it does not exceed 100 hairs, it is normal.

2. The main symptoms of hair loss are oily scalp, atrophy of hair follicles, easy to break hair, oily and inelastic hair. Male hair loss mainly occurs on the forehead and top of the head, with the hairline and temples moving upward, hair becoming sparse, yellow and soft, and baldness on the top of the forehead; female hair loss mostly occurs on the top of the head, and the hair becomes sparse, but it will not be "front bald" like men.

3. The growth and metabolism of hair are closely related to diet and nutrition. Iron, sulfur, vitamin A, vitamin E and high-quality protein are essential nutrients for hair growth. A balanced diet is beneficial to the health of hair. In your daily diet, you should add more crude fiber foods, eat more lean meat, whole grains, vegetables and other foods, and eat less fat, lard, animal offal and other foods with high fat content.
