Identify your hair type

Identify your hair typeThere are several types of hair around the world, varying in function of genes and ethnicity. They are three main categories of hair type: Asians, Caucasians (Western, European) and Negroid (African, Haitian and other Métis).

Curly or straight hair gene

Only one pair of chromosomes transmits the genes responsible for curly hair. So, if the father only has curly hair genes, the child has a 100% chance of inheriting of at least one curly hair gene and its hair will look curly. Curly hair genes are dominant over straight and smooth hair genes.

Asian hair (oriental)

Asians have straight hair because their hair follicle is almost round. That characteristic shall  ensure that hair grows straight. Hair color varies from dark brown to black, hair diameter is between 0.10 mm and 0.12 mm, and density per cm2 more or less 165 hair. Given their size, Asian hair are able to withstand loads up to 100 grams without breaking. The Vietnamese people have the thickest hair in the world.

Caucasian hair (Western, European)

Caucasian hair have different shapes such as straight, wavy, curly or frizzy. These differences are due to the fact that hair grows obliquely. The color of Caucasian hair varies from light blonde to black, the diameter varies between 0.07 mm and 0.1 mm, the shape of hair observed under a microscope is oval and density per cm2 of 200-300 hair. Caucasian hair represent the balance between the variety of shapes and strength. The population of Scandinavia has the finest hair known to date.

Negroid hair

Negroid hair are  of different forms ranging from very curly to frizzy because they are almost lying in the hair follicle. Hair color varies from dark brown to black. The hair diameter is between 0.06 mm and 0.09 mm, the cross section is flat and the density per cm2 is more or less 190 hair. This is the oldest human hair type, existing for over 200 000 years and is the basis for all other types. Important mutations in hair subsequently led to diversification of hair type.

Densitometry and analysis of the thickness of the hair will determine the normality of  hair by age and ethnicity.
