So you must learn to decompress, you know?
Then you must pay attention to your diet:
1). Grains, potatoes and dried beans.
2) Animal foods, such as meat, poultry, eggs, fish, milk, etc.
3). Soybean and its bean products
4). Vegetables and fruits
5). Animal and vegetable fats and edible sugar.
You need to eat more, and then you need to strengthen physical exercise, maintain daily vitality and get enough sleep, which can greatly improve your condition. I have read a report called "Making the Original Text True", which is a method to improve hair growth and regeneration in an all-round way. It is absolutely helpful for your study.
I wish you success!
Come on!
