Of all the hair types, coily hair is seemingly the slowest to grow. That's because it has the densest structure of all and is prone to shrinkage, which can make even the fastest-growing of locks look like they haven't budged.
Asian hair has the highest growth rate and is by far the most resilient hair type. African hair generally has a slower growth rate and less tensile strength and breaks more easily than other groups. Caucasian hair is somewhere in between the two.
Afro hair is a symbol of such power and fierceness but due to it's shape it's the weakest of all hair types. Under a microscope each strand is actually an oval shape unlike Asian and European hair which is circular.
Due to the implantation, hair also does not grow at the same rate. Asian hair grows the fastest, approximately 1.4 cm per month, Caucasian hair grows 1.2 cm, and African hair grows 0.9 cm due to its spiral structure.
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.
A general observation across experiments was that straight hair was perceived as younger, healthier, and more attractive than wavy hair and darker shades (medium copper and brown) were perceived more positively than blonde hair.
Nature's Rarest Palette: Red Hair Standing at the apex of rarity, natural red hair occurs in just 1-2% of the global population. This striking shade results from a specific genetic variant of the MC1R gene, requiring both parents to pass on the recessive trait.
Asian hair
Because of its extra diameter, it is also the strongest, and most resistant to damage. It is normally straight or only lightly wavy with a good amount of volume, because of its thicker diameter, even though there are typically less hairs per head (around 500,000).
Chinese men were less likely than White men to experience balding in any pattern. Black participants also had lower odds for temporal, vertex, and severe balding but to a lesser extent than Chinese men.
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, ...
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.
Type 1a – Straight (Fine/Thin) – Hair tends to be very soft, shiny and difficult to hold a curl. Hair also tends to be oily, and difficult to damage. Type 1b – Straight (Medium) – Hair has lots of volume & body.
Black hair is the darkest and most common of all human hair colors globally, due to large populations with this trait. This hair type contains a much more dense quantity of eumelanin pigmentation in comparison to other hair colors, such as brown, blonde and red.
Fine hair is the most fragile texture. It's easy to blow out and straighten, but doesn't hold a style well, tangles easily, and is more susceptible to damage and breakage.
The more you moisturize your hair and scalp with water, the healthier your head will be. Hair growth flourishes from a clean, healthy scalp. The bottom line is that dirty hair doesn't grow any faster than clean hair, so you may as well have a clean scalp and fresh tresses.
Many hair follicles stop producing new hairs. Men may start showing signs of baldness by the time they are 30 years old. Many men are nearly bald by age 60. A type of baldness related to the normal function of the male hormone testosterone is called male-pattern baldness.
Being a blonde doesn't affect your potential to be affected by male or female pattern baldness. If you're experiencing any form of hair loss, the professionals at RHRLI are here to help.

Caucasians Lose The Most Hair
After Caucasians, people of Afro-Caribbean heritage tended to experience the next highest levels of hair loss, with Asian men having the lowest hair loss rates.
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.
It has been reported that Asian hair is generally straight and is the thickest, while its cross-section is the most round-shaped among these three. Caucasian hair is generally straight or wavy and is the thinnest, while its cross-section is relatively elliptic.
Brunette hair is often seen as the most attractive by both men and women. Blonde hair is associated with youth and fun, making it appealing to younger audiences. Red hair has a unique charm that many find attractive, though it is less common.
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.
The rarest eye colors are red and violet, which are primarily found in individuals with albinism. Excluding those affected by albinism, green and gray eyes are considered the most uncommon.
Black hair or jet black hair is the darkest hair color. It has large amounts of eumelanin and is denser than other hair colors and is the commonly seen hair color in Asia and Africa due the fact that the people in these regions tend to have lower levels of tyrosinase in their bodies.
