Unlike dry scalp, an itchy scalp is a much more troublesome condition. It is not easy to treat using home remedies unless the cause behind it is identified. The technique is to recognize the reason behind itchy scalp and then use home remedies for that specific condition. Hence, the remedy depends on the cause of itchy scalp.
The symptoms of itchy scalp also vary with the cause of this condition. 
- The scalp itches and there is a sharp urge to itch. Once you itch, some of the urge is relieved but it can lead to more itching later on.
- Itching for long periods of time can lead to irritated, inflamed spots on the scalp.
- There may be pimples, rashes, insect bites, crusting and lesions on the scalp. They may not be easily visible because of the hair.
- Exercise aggravates the itching, or may even initiate it.
- Itching may also be accompanied by hair problems like hair loss, frizzy hair and dandruff.
In most people, the cause of itching can be determined. One should find the underlying reason and use remedies for that condition. However, sometimes there is just no obvious cause. In that case, one can use some common remedies to soothe irritated skin, lower inflammation and thus alleviate scalp itching.
