Hair morphology is one of the more conspicuous features of human variation and is particularly diverse among people of European ancestry, for which around 45% of individuals have straight hair, 40% have wavy hair, and 15% have curly hair.
Type 1: Straight Hair
Type 1A hair is very straight and fine, with no hint of wave or curl. As it is so straight and fine, when the natural oils travel to the ends, it tends to cause it to look like oily hair. It is the rarest hair type and is common among women of Asian descent.
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.
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.
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.
The texture of a person's hair is determined by the shape of their hair follicles. Your follicle shape is partly determined by what genes you have. Your DNA might cause you to have perfectly round follicles. In this case you would have straight hair.
In terms of both male and female preferences, blonde was considered the next best choice after brunette hair. According to the study, 27 percent of males chose the blonde photo of the woman to be the most attractive, while 23 precent of women similarly preferred the blonde hair.
Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes. Green eyes don't possess a lot of melanin, which creates a Rayleigh scattering effect: Light gets reflected and scattered by the eyes instead of absorbed by pigment.
Type 1 hair is hair that lies flat, or straight. Straight locks tend to be on the shinier side because the hair's natural oils are able to travel from root to tip. This hair category includes divisions 1A, 1B, and 1C. Type 1A is “stick” straight hair that has no hint of curl or wave.
Genetic factors appear to play a major role in determining hair texture—straight, wavy, or curly—and the thickness of individual strands of hair. Studies suggest that different genes influence hair texture and thickness in people of different ethnic backgrounds.
Straight hair is perceived as being more formal and business like especially if cut above the shoulders while longer loose hair indicates a less professional manner in the male dominant business world. Short hair also means you don't like to waste time on your hair, leaving more time for other things.
In fact, more people prefer curly hair to straight hair. Though beauty is seen differently by everyone, one thing is for sure; curly hair is getting a lot of love lately. In fact, in a survey conducted by StyleCaster, a surprising 58% of guys thought curly hair was sexier than other hair textures.
Asian hair is also the straightest hair of any ethnic group. According to HealthGuidance, African American hair texture varies. Some people have thicker, coarser hair whereas others have finer hair.
An increase in androgens in females can actually change the shape of the hair follicle from round to flat and this can instigate a change in texture from straight to curly.
Hair Type and 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. We all shed hair at various times in the hair growth cycle but having straight or curly hair doesn't have much of an impact either way.
Yes, natural purple eyes are possible. There are many different shades of blues and greys out there and many in-between colors. Although very rare, some people's natural pigmentation can even be violet or purple in color.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world's population. Hazel/amber is the next rarest of these.
In concurrence with both earlier studies, the results of this study indicated red hair as the least preferred hair color. In the Likert scale positive characteristic evaluation, as well as in the survey questions, brunettes were given the highest ratings of all three categories.
What hair color do guys find most attractive? Sorry blondes, but 60% of the men in question said they find brunette to be the most desirable. A third of the men polled (33.1%) said they think the most attractive hair color is brown hair, while 28.6% said they prefer black hair.
But for a few people, their hair actually changes shape and texture on its own — and not just because of the weather. Scientists don't know exactly why this happens, but it probably has to do with a combination of genetics, hormones and body chemistry.
It's very normal to have a mix of curl patterns on the same head of hair. It starts with your genetics. You see, the gene for curly hair is not completely dominant. It can remain dormant until activated and then it changes the shape of the hair follicle which changes the hair that grows from it.
Home hair straightening kits don't often last longer than 6 weeks. Permanent hair straightening done in a salon lasts anywhere from 4 to 6 months. Hair rebonding lasts about 5 to 7 months. Japanese hair straightening lasts up to 6 months.
