PATHOLOGY

Detailed explanation-1: -Because curly hair grows horizontally, the actual length can be difficult to perceive. To gauge the true length, therefore, you must stretch or elongate the hair to account for “shrinkage.”

Detailed explanation-2: -If your follicle is round, hair will tend to grow straight, while an oval follicle will give wavy hair and a hooked or elliptical-shaped follicle will give you curly hair. Straight hair follicles are vertically down into your scalp, while curly hair follicles tunnel at an angle.

Detailed explanation-3: -The shape of our follicle is a major determinant of our hair texture. If you look at the follicle of someone with straight hair you’ll see that it’s perfectly round. However, the follicle of curly hair has an oval shape. The flatter the oval shape, the curlier the hair.
