The factors that cause the rapid generation of skin cells are mostly related to the pressure of the immune system, such as temperature drop and work pressure, which will activate specific gene proteins and accelerate the generation of skin cells. In addition, Anthony Rossi, a dermatologist at the Kettering Memorial Cancer Center in Si Long, USA, pointed out that microorganisms living on the scalp can also disrupt the proliferation of skin cells. Although most of them are harmless, they may cause reactions in some people and lead to excessive cell proliferation.

How to Stop Scalp Itching The Reader's Digest website lists some simple ways to help alleviate the problems of scalp itching and dandruff without buying a dandruff shampoo: aspirin: it contains salicylic acid, just like many dandruff shampoos. You can grind two aspirin into powder and add it to the usual shampoo to wash your hair. After 1 ~ 2 minutes, wash it off, and then wash your hair with the usual shampoo. Baking soda powder: After wet washing your hair, scrub your scalp with about a palm of baking soda powder. Don't use shampoo, just rinse with water. Baking soda can reduce the hyperactive mold that causes dandruff. At first, the hair will dry, but after a few weeks, the scalp will produce natural oil, making the hair soft and dandruff-free. Apple vinegar: Dr. Mehmet Oz believes that the acidity of apple vinegar can change the pH of scalp, making it difficult for mold to grow. You can spray 1/4 cups of apple vinegar and 1/4 cups of clear water on your scalp in a spray can, then cover your hair with a towel, let it stand for 15 minutes to 1 hour, and finally wash your hair twice a week as usual. Mouthwash: For serious dandruff, you can wash it with alcoholic mouthwash after the usual shampoo procedure, and then protect your hair with the usual conditioner. Mouthwash has anti-mildew effect, which can prevent the growth of mold that causes dandruff. Coconut oil: before bathing, wipe the scalp with 3~5 tablespoons of coconut oil, let it stand for about 1 hour, and then wash your hair according to the usual shampooing steps. Lemon: Apply 2 tablespoons lemon juice to scalp, and then rinse with water. In addition, add 1 teaspoon of lemon juice to 1 cup of clean water for washing hair. Repeat every day until dandruff disappears. The acidity of lemon can balance the pH of scalp and avoid dandruff. Salt: Sprinkle a little salt on the dry scalp, gently scrape off the dandruff on the scalp, and then wash your hair according to the general procedure. Garlic: Garlic has antibacterial effect, which helps to eliminate bacteria that cause dandruff. In order to avoid excessive odor, you can add ground garlic to honey and scalp it with the mixture before the general shampoo step. Olive oil: drop 10 drop of olive oil on the scalp, then put on a shower cap for the night, and then wash it the next morning according to the general shampoo steps.
