Scratching these spots can lead to scabs. You can also use mineral oil or olive oil on your scalp. Let it sit for one hour, then brush out your hair. That may help with dry, crusty patches.

Coconut oil: Apply coconut oil if there is excessive itching on the head. This will help in moisturising the scalp. Dry scalp will be cured, and the problem of itching will also go away.
