Research from 2015 notes that Black hair has a thinner cuticle layer than other hair types, which means that strands may break more easily. Overall density: On average, people of African descent have fewer hair follicles than white people, at 90,000 for Black hair, compared with 120,000 for white hair.
Asian hair grows from a round hair follicle, while Afro hair sprouts from an oval one, and Caucasian hair follicles vary. Being a dead material, the hair subsequently keeps this original shape Asian hair is usually bone straight, Afro grows in a spiral like fashion, and Caucasian hair can be anything in between.
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.
Caucasians have the highest hair density among the ethnicities studied. Black people have the lowest. Asian people have hair density that falls somewhere in between.
Caucasian hair can be smooth, wavy or curly. Its colorimetry can vary from blond to dark brown. It grows obliquely, and grows about 1.2 centimeters per month. Caucasian hair has an oval shape.
Black hair is the darkest and most common of all human hair colors globally, due to larger populations with this dominant trait. It is a dominant genetic trait, and it is found in people of all backgrounds and ethnicities.
Caucasian, Asian and Indian hair samples were put to the test for the World's Best Hair study. Their results put an end to any splitting of hairs over the issue: in terms of health, the Indian hair is the best, topping other ethnic groups on all four counts.
There are two reasons why we believe African hair texture is genetic. Firstly, the texture is universal in Africans, while nearly absent from other ethnic groups. Secondly, it is consistently passed down to the children in each new generation.
This may be related to differences in body composition, which is known to differ between ethnic groups. 62, 105 More specifically, black adults were found to have a relatively higher muscle mass (leading to a lower sarcopenia prevalence) compared to whites and Asians.
What race is known for straight hair? Caucasian. Caucasian people have rounder hair follicles, resulting for the most part in straight or wavy hair.
Compared to silkier hair African-American hair contains more lipids, or fats, but the lipids are less bonded which is why the hair loves oils so much. Along with that, the follicle size is much thicker and it has a flattened elliptical cross section causing it to be curlier than other hair types.
Natural Hair
Even though natural black hair is dry, the build-up of debris can make it feel greasy if not washed regularly. You should ideally wash your natural black hair once every seven to fourteen days. Use a mild cleansing shampoo and a gentle conditioner.
Fros don't absorb as much moisture as our caucasian cousins' hair, added to this the structure of our hair (curls and kinks, and increased density) means that nutrients often don't travel along the length of our strands as well as we'd like.
Asian hair shows the fastest growth rate in comparison to the other two hair types. African hair has the lowest growth rate.
A 2005 study in the journal International Journal of Dermatology also found a difference among races in the rate of hair growth. For example, Asian hair grows the fastest, while African hair grows the slowest.
The dark skin protects against the sun and that the hair is curly helps to protect their head. Whether curly hair is better or not, that is the way they evolved. You should ask why people have straight hair and why they are white when they need protection against the sun. It is because of a recessive albinism gene.
Abstract. A rare muscle named Levator Submandibuli (LS) or Banjo muscle (after the author) is present in few persons. It is situated in the submandibular region superficial to the mylohyoid muscle.
So, why is Afro-textured hair so fragile? With its tight curls and twists, is more prone to breakage for several reasons. Its shape increases tangling and makes combing harder. The shape also creates internal stresses when the hair is unbent, untwisted or stretched that lead to fracturing.
Afro-textured hair, or kinky hair, is a human hair texture originating from sub-Saharan Africa. Each strand of this hair type grows in a tiny, angle-like helix shape. The overall effect is such that, contrasted with straight, wavy, or curly hair, afro-textured hair appears denser.
Sickle cell diseases are especially common in people of African or Caribbean ancestry. They cause your body to make red blood cells that are sticky and curved and back up in your liver, and they die faster than your liver can filter them out. Bilirubin from these cells builds up in your body, causing jaundice.
Certain races have higher rates of hair loss compared to others. Caucasians have the highest rates out of all the ethnic groups. On the opposite end of the spectrum, Native American Indians, Inuits, and Chinese have the lowest rates.
In general, however, the highest rates of male pattern baldness are found among Caucasian men. The second highest rates belong to Afro-Caribbeans. Native Americans, on the other hand, do not struggle much with male pattern baldness. As mentioned, pattern baldness is genetic, that is, hereditary.
Asian and black skin has thicker and more compact dermis than white skin, with the thickness being proportional to the degree of pigmentation. This likely contributes to the lower incidence of facial rhytides in Asians and blacks.
