An itchy scalp can cause discomfort and scratching, as well as interfere with your ability to concentrate at work or sleep through the night. A variety of factors contribute to your risk for itchiness, although in many cases treatment won't require a doctor's care, reports the American Academy of Dermatology.
Significance
A rash, psoriasis or even conditions like liver disease and kidney failure are common triggers of itchiness on your scalp that cause persistent scratching and irritation, according to the Cleveland Clinic. Treatment for an itchy scalp often includes nonprescription creams and lotions or a cool bath, while severe cases may require stronger medications and a doctor's care. Your doctor will determine the appropriate remedy for your scalp based on your symptoms and existing health conditions.
Identification
Dandruff is the most common cause of an itchy scalp and is typically accompanied by white flakes of dead skin in your hair. Wash your hair daily with a gentle shampoo to lower your risk for excess oil and skin cell buildup that promote dandruff. Shampoos with zinc pyrithione, salicylic acid or selenium sulfide typically help relieve itchiness and enhance the condition of your scalp. Apply the shampoo daily until the itchiness fades, and then scale back to two or three times weekly if necessary, says MayoClinic.com.
Prevention/Solution
Limit your use of hair sprays and waxes, along with styling gels and mousse, as these products increase your chance of scalp itch. A healthy diet also benefits your scalp, so ask your doctor about a nutrition plan that includes sufficient amounts of B vitamins, zinc and some fats. Get plenty of relaxation, as stress weakens your immune system and makes your vulnerable to diseases and conditions that cause itchiness, reports the Cleveland Clinic. Avoid scratching when possible.
Considerations
Shampoo that contains tea tree oil may relieve the discomfort of an itchy scalp, although some people experience allergic reactions when exposed to the shampoo. Sunlight can also reduce itchiness, but limit your exposure and wear sunscreen, since too much sun puts you at risk for skin cancer.
Expert Insight
MayoClinic.com reports that if a shampoo remedies your itchiness temporarily and then loses effectiveness, try switching to another shampoo for a few days, and then revert back to your original shampoo. Massage the shampoo thoroughly into your scalp for best results, and give the product time to work by keeping it in your hair for at least five minutes.
Potential
Contact your doctor if shampoo and other at-home treatments don't resolve your scalp itch or if you experience redness or swelling. Your doctor may recommend a steroid lotion or prescription shampoo, or he may perform tests to determine if your scalp itch is caused by a serious medical condition.
