While most people are simply annoyed by an itchy scalp and do not find that it disrupts their day, there are situations where it is indicative of a more serious condition and, as a result, should be dealt with as soon as possible. The sooner the condition is treated, the sooner you are able to return to your life without the burden of an itchy scalp.
A plethora of different disorders and conditions can cause an itchy scalp, but the most common cause is attributed to general allergies, as well as mild allergic reactions or sensitivity to an ingredient in a new hair product, such as shampoo or conditioner. If flakes or dandruff are also present, then the solution is often as simple as switching to a new, less drying product and discontinuing use of old products which have been proven to irritate the scalp. If you have kept the boxes and labels that come with your hair products (from shampoo and conditioner to hair dyes and hair sprays alike), you may be able to isolate a common ingredient that is causing the irritation, and can eliminate items including that ingredient from your home. Unfortunately, if the problem continues after this has been done, it is likely that the itchy scalp is a symptom of another issue.
Dermatitis and eczema are both known to cause one’s scalp to itch, but it is difficult to diagnose these conditions without first seeing a doctor. Psoriasis can also cause a rash to form on the scalp, which will undoubtedly itch, but this is not a common trait of psoriasis, which tends to appear more on the knees and elbows than on the scalp.
Another common cause of itchy scalp is an infestation of head lice. Many people fall for the myth that only children are susceptible to lice, but this is not true; if you come into contact with any person who is carrying lice, there is a chance you may end up with them as well. If this is the case, you will be able to see tiny egg casings along the shaft of your hair. When infested with lice it is recommended that all bed sheets, clothing, stuffed animals, and throw rugs are washed in hot soapy water. It is also extremely important to purchase a special de-lousing wash, many varieties of which can be found at most drugstores. Once the lice have been eradicated, itchy scalp should go away.
There are many ways to treat an itchy scalp without consulting a doctor, however, it is always preferable to speak to a licensed professional. In the meantime, many organic shampoos that do not contain silicones have been said to eliminate the itch. Many people swear by rinsing their hair with apple cider vinegar (which is also a common home remedy for dandruff) and using a deep cleansing treatment to remove all possible product build-up is also recommended. Tea tree oil and rosemary products have been shown to soothe itchy scalp, as well. Depending on the cause, itchy scalp can be very easy to cure.
