Although African hair is drier more brittle and susceptible to chemical and physical damage due to its spiral structure, it also has some advantages, especially in hot climates where it forms a natural barrier against the sun.
Type 4 (Coily Hair)
Coily hair (Type 4) is the driest of all curl types and requires extra moisture and care.
Asian hair and Caucasian hair handle stress and fatigue well. Asian hair has the highest hardness and elasticity. It is resistant to stretching and can withstand a traction force of 60 to 65 grams.
Reason for that is, whilst African hair produces a lot of protective oils called sebum (more than Caucasian and Asian hair) it doesn't spread evenly along the hair fiber due to curls. Without lubrication, the fibers become dry. When brittle strands flake and roughen, hair becomes coarse to the touch.
Sub-Saharan Africans, East Asians and native Americans have little or no body hair. Sub-Saharan Africans and East Asians are the least hairy people. Northern Europeans, Mediterraneans and middle eastern are the most hairy people.
East Asian men (such as those of Chinese and Japanese ancestry) are next on the list of those least likely to experience hair loss. For example, while around half of Caucasian men will experience some degree of androgenetic alopecia, a 2010 study of Chinese men found only about 13% did.
Anthropologist Joseph Deniker said in 1901 that the very hirsute peoples are the Ainus, Uyghurs, Iranians, Australian aborigines (Arnhem Land being less hairy), Toda, Dravidians and Melanesians, while the most glabrous peoples are the Indigenous Americans, San, and East Asians, who include Chinese, Koreans, Mongols, ...
Also, there is the retrocurvature of the hair follicle, which is different from the straight shape of Caucasian follicles. Knot formation due to intertwined hair fibers makes combing difficult and predisposes the African hair to breakage during normal grooming.
Woolly hair is a difficult to brush hair, usually present since birth and typically most severe in childhood. It has extreme curls and kinks, occurs in black people and is distinct from afro-textured hair.
Growing afro hair can sometimes seem like an impossible task. One thing is for certain, however, and that's that it requires dedication and a whole heap of patience. Scientifically, black hair is the slowest growing hair type due to its elliptical shape and only grows about one third of an inch per month.
Caucasian hair has a thinner diameter than Asian hair (60 – 80 µm in diameter), and therefore tends to appear 'finer' than Asian hair, even though there is typically more hair on the head (around 700,000).
Skin barrier function is reportedly stronger in darker skin tones (the stratum corneum is the skin barrier). Asian skin is reported to have similarities with Caucasian skin in terms of water loss and has the weakest barrier function.
There is no scientific basis to claim that any particular ethnicity or race has "more dominant" genes than others. Genetic diversity exists within and across all human populations. All humans belong to the same species, Homo sapiens, and share the vast majority of their DNA sequence.
Type 1A: The rarest hair type, this one is very straight and fine with a “wispy” appearance. It's very difficult to get it to hold a curl. Type 1B: Though still straight, this type has a medium (rather than fine) texture and a little more volume.
Dry hair occurs when your hair doesn't get enough moisture or fails to retain it. This can make hair appear brittle, lifeless, and frizzy. The hair shaft loses its protective outer layer, the cuticle, making it vulnerable to environmental damage and breakage.
So now that we know how we get straight or curly hair, does a particular type of hair type make you more susceptible to hair loss? All things being equal, there's no evidence that there's any difference in the natural cycle of hair loss for people with either straight or curly hair.
Of course, Jesus was a Jew. He was born of a Jewish mother, in Galilee, a Jewish part of the world. All of his friends, associates, colleagues, disciples, all of them were Jews. He regularly worshipped in Jewish communal worship, what we call synagogues. He preached from Jewish text, from the Bible.
According to the American Journal of Physical Anthropology, East Asians have the least body hair. Scandinavians actually have the most, it is just hard to see because their hair is usually blonde and matches with their skin tone.
In this verse John describes Jesus as having hair like white wool and snow. The prophet Daniel wrote that he saw the Ancient of Days, describing Him as having hair that resembled wool (Daniel 7:9). Seen as having such a resemblance to God the Father, Jesus is eternal.
African hair is seen to be much thicker and more dense meaning that the hair follicles are larger. Density represents the amount of hairs that grow from the head, with denser hair resulting from more hairs growing closer together from the scalp. An individual with high-density hair creates a fuller appearance of curls.
Another advantage of black hair is that darker hair seems to always look healthier than lighter colors. The darker hair dye can make the strands look thicker, leaving you with fuller looking hair. Plus, black will reflect light better, so your hair looks shinier and more nourished.
After a certain population analyzed, researchers found that women with brown eyes chose blond hair more often, while women with other eye colors preferred brunette hair. Furthermore, the results showed that women care about hair length, with long black hair being preferred by the majority of women.
Based on these findings, we hypothesize that the thickened cuticle layer in pubic hair may have evolved as a defence mechanism against chemical damage from urine, urea and ammonia. Keywords: FT-IR imaging; cortex; curly hair; cuticle; hair; pubic hair; scalp hair; urine effects.
There is no specific ethnicity that can't grow facial hair, but East Asian individuals, such as Japanese and Chinese, tend to have less facial hair and slower growth rates compared to other ethnicities.
The researchers found 68% of white men reported hair loss compared to 64% of South Asian men and 59% of black men. (The relatively small differences are partially explained by the fact the white men in the study were older). There are also forms of hair loss that are known to be more common in people of colour.
