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. This causes the strands to become more brittle, which contributes to the hair's texture.
The texture of black hair originates from the curl pattern of their African ancestors who spent a long time in the sun. As with any genetic trait, certain hair types are more dominant than others in a family lineage. These genetic factors also mean that curly kinky hair is very common in many African tribes.
Understanding the differences between these two hair types can help individuals make informed decisions about their hair care and styling. African American hair is typically coarser and has a thicker texture than Caucasian hair.
Frizz occurs on afro hair and curly hair more than any other types. Afro hair produces plenty of protective oils called sebum, but the oil struggles to spread evenly along the hair fibre due to the curly nature of afro hair.
You can use oils like castor oil, coconut oil, jojoba oil, almond oil, etc. You can even add a few drops of essential oil for the best results. If you have dry hair, applying oil is one of the best ways to revive.
Chemical treatments and heat styling alike can cause changes in hair texture. Coloring, relaxing, perming, blow drying on high heat, and flat ironing can all damage hair, leaving it dry and wiry.
The average diameter, or thickness, of Asian hair is from 80 to 120 µm, compared to 65 µm in Caucasian hair and 55 µm in Black hair. The average diameter of Hispanic/Latino hair tends to fall between that of Asian and Caucasian. Caucasians have the highest hair density among the ethnicities studied.
According to research hair grows an average of 1.3cm per monthand although it's true tha black people's hair grows slower than this, the difference is not extreme. The only reason black hair appears to grow slower is because it is extremely curly whereas other types of hair grows straight or in bigger curls.
Afro-textured hair is a human hair texture originally prevalent in many regions with hot climates, including in sub-Saharan Africa. Each strand of this hair type grows in a tiny, angle-like helix shape.
Generally, the East Asian and Native American population has straight, black hair with a very thick cuticle layer and South Asians have thick, wavy or curly hair, while the general hair type seen in black African hair is thick, curly and dense with more hair growing from the head.
The African hair is generally curly or frizzy, and grows almost parallel to the scalp. It has the slowest growth rate of 0.9 centimeters per month due to its spiral structure which causes it to twist on itself as it grows. African hair has a flattened shape.
This Afro hair category, as largely seen in the curl pattern of black people, is naturally very dry and wiry, making it very fragile.
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.
Higher Concentration of Melanin
Most Africans have high levels of melanin that results in yellow eyes. Melanin determines the color of your skin, sclera and eyes. When this concentration increases, the eye color becomes light yellow or muddy brown.
Follicles that are more oval in shape cause curlier hair to grow. Very tightly coiled hair is due to the nearly flat, ribbon-like structure of their follicles. This hair texture is very common in people of African ancestry. Not only is African hair often coiled, it also has a unique texture.
Hair Growth Rate
Asian hair shows the fastest growth rate in comparison to the other two hair types. African hair has the lowest growth rate.

Asian hair follicles are round, usually very straight, and strong. While not as dense as its counterparts, the hair is less likely to experience hair loss or breakage. Asian hair is also the fastest growing, at over half an inch per month. Caucasian hair can be stick straight, wavy, or curly.
According to a global study based on 4 characteristics that determine healthy hair – thickness, tensile strength, shine, and smoothness – Indian women have the best hair in the world.
Hair density.
Asians have approximately 150 hairs for every square centimeter on the scalp with about 80,000 hair follicles on an adult scalp. African Americans have the lowest hair density, averaging around 130 hairs per square centimeter and about 60,000 hair follicles on an adult scalp.
One popular myth is that hair loss in men is passed down from the mother's side of the family while hair loss in women is passed down from the father's side; however, the truth is that the genes for hair loss and hair loss itself are actually passed down from both sides of the family.
If your hair is feeling coarser, drier, and stiffer in recent months or years, it may not be your imagination. Turning gray is just one of the many changes your hair goes through as you age. Changes in your hair's thickness, texture, and growth location—too little in some places, too much in others—can also occur.
