Your hair does need certain oils to stay healthy. But, an excessive build-up of those oils will only cause more harm than good. There is a fine line between being able to give your hair texture and taking care of the health of your scalp. That balance is different for everyone. If it is skewed one way or another, some skin condition could potentially occur. As you can see, there are plenty of reasons for an itchy scalp when hair is dirty.
There is some good news. There are plenty of ways to get rid of a dry and itchy scalp , too. Knowing more about hair and scalp health can help you figure out the best hair-washing schedule for you.

Your natural sebum protects your scalp from losing moisture and drying out too quickly. Too much oil, however, can cause greasiness, allowing fungi and bacteria to grow and resulting in dandruff and other scalp conditions.
Dandruff and an oily scalp can lead to hair breakage. Scalp is also skin. Hence, acne can develop on the scalp as well.
For similar reasons, curly, coarse hair tends to be much drier than straight silky hair. In the case of curly hair, the oil needs to travel along corkscrew-shaped strands to moisturize to the ends.
