Caucasian hair is generally straight or wavy and is the thinnest, while its cross-section is relatively elliptic.
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.
A gene variation of EDAR that arose about 30,000 years ago seems to give some people thicker strands of hair. More than 90% of Han Chinese, 70% of Japanese and Thai people, and 60% to 90% of Native Americans carry the “thick hair" version of the gene.

There are racial differences, however, in the incidence of male pattern baldness. The highest rates are found among Caucasians, followed by Afro-Caribbeans. Chinese and Japanese men have the lowest rates. For some unknown reason, this form of hair loss is does not occur among Native Americans.

Africans have the widest and most prominent nose compared to other ethnic groups. Their noses are featured with enlarged nostrils, wide and rounded tips and a lack of protruded nasal bridge.
Genetic hair loss is usually caused by a sensitivity to certain hormones, specifically androgen (the male hormone). This genetic predisposition causes your hair to grow back thinner and shorter with every passing hair growth cycle.
Generally, muscle mass is highest in African Americans, followed by Caucasians, Hispanics, and Asians, while percent body fat is highest among Asian subjects (Wang et al., 1994; Silva et al., 2010) .
100% REMY processed to the highest international standards. The finest human hair is processed in the most sophisticated Malaysian style. Soft, luscious, shiny, bouncy, light-as-air hair.
Geneticists at the University of Tokyo and several other institutions in Japan, Thailand, and Indonesia have now used the HapMap to explore why Japanese and Chinese people have thick hair: The cross-sectional area of East Asian hair fibers averages about 30% larger than that of Africans and 50% larger than that of ...
Human hair comes with all sorts of colors, textures and shapes. Notably, African hair is more coiled and dry; Asian hair is straighter and thicker; and Caucasian hair is somewhere in between with around 45% having straight hair, 40% having wavy hair, and 15% having curly hair.
African hair produces plenty of protective oils, called sebum, which keeps our hair healthy. In fact, African hair actually produces more oils than Caucasian and Asian hair. However, due to the tight curls, the oil doesn't spread evenly along the hair fiber. Without lubrication, the fibers can become dry.
Nose 14: The Anonymous
The rarest of all the nose types, this flat, rounded shape was found in only one face out of the 1793 considered - 0.05 percent of the population. For this reason, the study author says there are no important figures to represent this nose.
The Nubian nose is also called the wide nose. This nose shape is often seen in African races.
Mehmet Ozyurek from Turkey holds the record for Longest Nose on a Living Person - 8.8 cm (3.46 in) long from the bridge to the tip.
In straight type, thin hair was judged most attractive, whereas in wavy type, hair with mean diameter received the highest attractiveness judgments. In conclusion, there was considerable variation in age, health and attractiveness perception of hair with regard to effects of hair diameter, type, and color.
Your hair density is generally highest at your vertex, the area at the back of your head also known as your crown.
Brown permanent hair colors are the most long-lasting.
Rarest: Red Hair.
Red hair requires both parents to give the child a copy of a mutated MC1R recessive gene, so only about 1-2% of the global population have red hair. Rare indeed! Think of the recessive, mutated red hair gene as a tank top.
Who lived longer, blondes or non-blondes? The researchers showed that the blondes had significantly lower all-cause death. Still, they had a higher mortality from skin cancer. Contrasted and compared to the non-blondes, the blondes had significantly reduced all-cause death.
Hair type 1A is super-straight. It doesn't even hold a curl! 1A is the rarest hair type. It is usually found on people of Asian descent.
