If you’ve ever wondered why your head is itchy, you’re not alone. Many people suffer from the same itch all over their head. For some people, it can be caused by allergies, other ingredients in food, or just plain old irritability. For other people, the itch isn’t as bad as it seems. Read on to find out what causes your head to itch. You’ll be on your way to a healthier you!
Dry air can be one reason your head itch. Indoor heat and cold air both deplete your scalp of its natural oils, which are responsible for scalp lubrication and hydration. To combat dryness, apply a moisturizing hair conditioner every few days, or use a scalp mask once a week. Avoid wearing hats during the itchier seasons. While the problem can be frustrating, over-the-counter solutions can help.
If the problem is chronic, it may be caused by a more serious condition, such as psoriasis. This chronic skin condition causes red, scaly patches on the scalp. Tinea, another common cause, is a fungal infection of the scalp. Head lice, meanwhile, can be a contagious small insect that cause an itchy scalp. While over-the-counter shampoos may help to relieve your itchy scalp, they are not a cure for head lice.
In some cases, the itchiness is caused by dandruff. This is an early warning sign of dandruff, and often starts before the flakes appear. Dandruff occurs when the scalp becomes inflamed. Microbes break down the scalp’s natural oils to form oleic acid, which causes an itchiness. Up to 1 in 2 people are sensitive to this substance, so if you’re prone to the dandruff fungus, it’s probably best to consult your physician.
