The 3 ethno-hair profiles
There are 3 “original” ethno-hair profiles, each with their own characteristics: color, texture, structure and even implantation in the scalp…
Due to these differences, hair does not grow in the same way or at the same speed in people of different ethnic origins.
Asian hair is usually straight and either dark brown or black in color. It grows perpendicularly to the scalp. This hair type has the fastest growth rate at approximately 1.4 centimeters per month.
A strand of Asian hair has a somewhat round, even shape. Nonetheless, Asian hair has the lowest density of the three ethnicities.
Caucasian hair can be straight, wavy or curly. Its color can vary from blond to dark brown. This hair type grows diagonally and at a rate of about 1.2 centimeters per month.Caucasian hair strands are oval in shape. Caucasian hair density is the highest of the three ethnic categories and is therefore the fullest.
African American hair
African hair is generally characterized by tight curls and kinks, and grows almost parallel to the scalp. This hair type has the slowest growth rate, 0.9 centimeters per month, due to its spiral structure that causes it to curl upon itself during growth. An African hair strand has a flattened shape.
African hair has a much higher density than Asian hair.
