Why Does Your Scalp Get Itchy?

Why Does Your Scalp Get Itchy? Posted on 24/06/2016

There can be several reasons for an itchy scalp, and many of them are easy to fix. If you’re considering scalp treatments in Singapore, here are some possible causes for itchy scalp that can help you to avoid this problem in the future.

Seborrheic dermatitis or dandruff is the main reason that the scalp will start to itch. The itching sensation in the scalp is caused by an overgrowth of yeast in the body, which leads to inflammation. Yeast naturally lives in the parts of the body that are hairy, but when there is too much yeast, the scalp will become flaky or red and start to itch. Treatments for this scalp problem can include medicated shampoo that contains zinc or selenium pyrithione. Milder forms of the shampoo can be found at the grocery or drug store, but you may need to ask your doctor for a stronger version if the store-brought brands are not working.


Psoriasis is another reason for itchy scalp. Psoriasis is an autoimmune condition in which skin cells create scaly, red patches on the scalp and various parts of the body. Even though psoriasis isn’t contagious, you are more likely to develop psoriasis if a member of your family has it. Shampoo and hair treatments that contain salicylic acid and/or coal tar can be effective in controlling psoriasis and soothing the scalp to reduce itching.


Your scalp can also start itching if you are allergic to a product that you’re putting in your hair. Dyes, hairsprays and gels that are made from harsh chemicals can irritate your scalp and cause redness and itching. If you have eczema, you are likely sensitive to a number of products, and adding certain hair products to your regimen could make your scalp itch. To find out exactly what is causing your allergic reaction, you’ll need to visit a dermatologist who can thoroughly examine your scalp and provide you with the best treatment options.

Be sure to tell your doctor or dermatologist if you start to develop sore spots on your scalp, or if the itching is persistent and doesn’t subside with the use of medicated shampoos. These may be signs that it’s time to adopt a customized regimen to get rid of scalp irritation.
