Full Answer

Caucasian hair grows at a skewed angle from a round-shaped follicle. Its rate of growth is 1.2 cm per month, which is slower growth than Asian hair and faster growth than African hair.

Caucasian hair has the greatest density of the three hair types. Among white people, the number of hairs on a head can vary by color. While blondes have around 146,000 hairs, those with black-colored hair have 110,000, and brunettes tend to have around 100,000 hairs on their head. Redheads have the lowest density among Caucasians, averaging about 86,000 hairs per head. Asians average between 80,000 and 140,000 hairs per head and those with African hair have between 50,000 and 100,000 hairs.

Even though each hair type can differ in thickness, texture, color, rate of growth and density, they are all mostly composed of a protein called keratin. Each strand also has three layers; cuticle, medulla and cortex.
