Users can use potassium permanganate solution to wash their hair according to the doctor's advice, but it should be noted that the concentration of potassium permanganate must not be too high, so as not to cause certain irritation and corrosion to the scalp, and even lead to local scalp hair follicle necrosis in severe cases.

If users use potassium permanganate solution to wash their hair, they should pay attention to keeping a regular routine and avoid eating some spicy food. Users are advised not to use it frequently. Frequent use of potassium permanganate solution may change the local inherent environment of scalp, thus making it easier for bacteria to invade.

Precautions for users to wash their hair:

1. The number of times users wash their hair should be controlled, usually four times a week.

2. When washing your hair, the water temperature should be appropriate, neither too cold nor too hot, otherwise it will do great harm to your hair.

3. When washing your hair, pour the shampoo on your hands first, and then put it on your hair. Shampoo focuses on scalp washing and dandruff removal.

4. After shampooing, keep the moisture in your hair at about 50%. Pour conditioner or hair mask on the palm of your hand, knead and apply it to your hair. Hair conditioner or hair mask mainly acts on hair, not scalp.

5, gently massage, let the hair evenly wrapped in conditioner or hair mask. Put on a shower cap and let it stand for a few minutes. It is best to steam with hot steam.
