Your hair is dry, which is related to heredity. You can only improve through aftercare the day after tomorrow, but you can't completely change it.
First of all, you should pay attention to your diet. This ordinary person generally doesn't care. In fact, it is very important, and it can be said to be the key.
Diet can't eat spicy and exciting items, control alcohol and tobacco, and avoid eating peppers. As long as you get drunk after eating Chili or drinking strong liquor, your scalp itching and dandruff will "revive" the next day! So control your diet, develop good eating habits, eat more fruits and vegetables and drink more boiled water. Ensure the quality of sleep. Get twice the result with half the effort and get immediate results!
Secondly, care for your hair reasonably and scientifically, and choose shampoos suitable for dry and damaged hair, such as Palmolive and Wang Ba. (Note that it must be marked "Suitable for dry hair" and never "Suitable for neutral hair", let alone "Suitable for all hair"). According to my experience, there are few good brands of shampoo suitable for dry hair. Merchants rarely buy goods, and it is said that the profit is low. I wonder if it's true.
The frequency of shampooing should be small, and you can wash your hair every two or three days at first. Cooperate with Kang Wang shampoo in the pharmacy, massage the scalp and rub the hair carefully for 10 to 20 minutes each time, and then rinse off with clear water. Then protect your hair with ointment.
Meet the above requirements, there will be results! Wish you all the best!
