Dandruff is a kind of skin disease that is harmless to the body. Almost all people have experienced dandruff in a certain stage of life. When the scalp becomes greasy, some white dead skin will appear on the hair or shoulders. Although dandruff is harmless, too much dandruff is always embarrassing. Here are the reasons for my dandruff. I hope I can help you.
What is the reason for dandruff?
Skin cells continuously renew and metabolize on the scalp, so it is normal for dead skin cells to fall off. However, sometimes because scalp cells are renewed and shed faster than normal, scalp oil causes dead skin cells to gather together and appear white flakes.
1. Dandruff may be caused by many factors, including oily skin, sensitivity to hair care products and some skin diseases, such as seborrheic dermatitis or eczema.
2. If you don't wash your hair often, oil and skin cells on the scalp will accumulate, leading to dandruff.
3. Excessive reproduction of yeast like fungi can also lead to excessive dandruff, which is generally caused by excessive stress, hormones, excessive scalp oil or immune system problems. Because more men have dandruff problems, some researchers believe that male hormones play a role.
4. Many people believe that the problem of dandruff is due to dry scalp. In fact, oily scalp is more likely to lead to excessive dandruff. According to the University of Mississippi Medical Center, Malassezia and pityrosporum feed on oil in the scalp. This means that the more oil your skin produces, the easier it is for these bacteria to thrive.
5. Allergic to hair care products. Sometimes, skin allergies to certain ingredients in hair care products or hair dyes can also lead to scaly dandruff.
6. Not eating enough zinc, B vitamins and certain types of fat can increase the risk of dandruff problems.
Symptoms and complications of dandruff
Symptoms of dandruff include flaky or scaly white dead skin on the hair and shoulders, scattered over the whole piece of hair. Usually accompanied by itching.
Dandruff affects hair growth
Studies have shown that the deterioration of flaky dandruff can lead to hair loss in some people. Large and thick scaly dandruff will adhere to hair follicles, adversely affect hair growth and even cause hair loss.
If it is caused by seborrheic dermatitis, dandruff is usually greasy and red. When skin cells die, it turns yellow. Seborrheic dermatitis can also cause other complications, such as yellow or reddish scales on the hairline, in and around the ear, nose and chest. Affected newborns may develop a thick yellow crusty rash on their scalp, commonly known as a cradle cap.
How to do more dandruff? How to remove dandruff?
Dandruff can usually be controlled by appropriate treatment. First try to wash your hair with a non drug shampoo, massage your scalp hard, and then rinse it off. Regular shampoo can remove dandruff, reduce scalp oiliness and prevent the accumulation of dead skin cells. If this doesn't work, use a special dandruff shampoo.
When choosing over-the-counter shampoo, you need to choose products containing dandruff removing ingredients, such as ketoconazole, selenium sulfide, salicylic acid, sulfur, coal tar or zinc pyridinethione. Try different products until you find the right one.
If over-the-counter shampoo still doesn't improve or even worsen after 2 weeks, you should consider seeing a doctor. The doctor may prescribe a corticosteroid lotion. But do not use it for a long time. It can thin the skin and cause other side effects. Infants cannot use it either, because infants are more absorbable than adults.
Other studies on Anti Dandruff
According to a 2012 study, green tea has shown potential for the treatment of dandruff and psoriasis. Research suggests that a special formula of green tea that can penetrate the skin can fight excessive scalp cell growth, oxidative stress and inflammation.
Another popular treatment is tea tree oil. By applying a small amount of tea tree oil on the scalp, you can treat your dandruff, which is due to the natural antibacterial properties of tea tree oil. Tea tree oil can also dredge hair follicles and nourish hair roots by moisturizing scalp and hair, which helps to solve problems such as itching and excessive oil.
