Dandruff is the most-common cause of an itchy scalp, notes EverydayHealth, and the best way to treat it at home is to use over-the-counter shampoos containing tea tree oil, selenium or zinc pyrithione. A dry scalp can also cause intense itching, and moisturizing the scalp can provide relief.
Repeated chemical treatments, such as relaxers, keratin treatments or permanent color applications, can also rob the scalp of moisture and cause itching, so minimizing these treatments can help, notes EverydayHealth. Blow-drying the hair excessively and using hair products that strip moisture from the scalp, such as stiffening hair sprays, may also cause itching, so allowing the hair to air-dry after washes and avoiding moisture-stripping products when styling may also provide relief.
When the scalp itches, it is best to moisturize the scalp instead of scratching it, explains EverydayHealth. Products with moisturizing and protecting ingredients like silicone or dimethicone can ease itching, and moisturizing conditioners help soothe the scalp. Washing the hair with very hot water can also strip the hair of its natural oils, which can lead to dryness an itching, so it's best to wash the hair using cool water. dditionally, putting lotion in the refrigerator before the shower is recommended because it is more soothing to the skin when applied while cold.
Those who have uncontrollable itching or suspect they have a condition that's causing the itching, such as psoriasis, alopecia or ringworm, should see a medical practitioner, notes Healthline.
