1. Straight hair
Straight hair has no natural curl to it. Natural oils from the scalp tend to move more easily down the length of each strand, which can give straight hair an appealing natural glow. On the other hand, this can lead to greasy looking locks. Dry shampoo should help to cleanse oily hair without adding to the problem.

2. Wavy Hair
Naturally, wavy hair should form an S shape. In many respects, wavy hair is a happy medium between straight and curly hair, but it isn’t always easy to tame.

3. Curly Hair
Curly hair is characterized by naturally defined ringlets that tend to prevent the scalp’s natural oils from spreading down the full length of the strands. This means curly hair is prone to dryness.
