Everyone's hair grows at different rates. Many factors — including genetics, sex, and age — can influence the speed of hair growth. Hair grows out of follicles, which are small pockets inside the skin. Each follicle contains a hair root, which is made of protein cells.
If you have fast-growing hair, the main reason is your DNA and hair thickness. Several other things, like environmental factors, age, stress, and medications may have an impact, but your DNA mostly calls the shots in this department.
“The speed at which hair grows is determined by genetics but there are other factors that can affect the growth rate. Age, diet, stress, hormonal fluctuations, scalp health, hair care practices, medications and other health conditions can potentially influence hair growth,” said master hair colorist, Stephanie Brown.
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.
So, can your genes also play a role in hair growth? Simply put, yes. Your genes are involved in several aspects of your hair's ability to grow, from your hair growth cycle to your risk of common hair-related issues such as male pattern baldness (androgenetic alopecia, or genetic hair loss).
"Hair growth signifies healthy hair, if it is growing from the scalp at a slower rate than a quarter inch per month then something is wrong internally," hairstylist Kali Ferrara told INSIDER.
The blood in your scalp goes to the follicle and supplies oxygen and nutrients to the hair root, which helps your hair grow. As your hair grows, it will push through your skin and pass by an oil gland. It's the oil from this gland that makes your hair shiny and soft.
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, 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.
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.
We'll cut straight to it: On average, hair grows at a rate of about half an inch per month, or six inches per year. Each hair on your head grows from an individual follicle.
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.
Hair grows about 1/2 inch per month on average , So it will take 2years for 12 inches.
The quick answer is, on average, hair grows about ¼ inch to ½ inch a month, according to Bridgette Hill, certified trichologist and founder of Root Cause Scalp Analysis. Of course, this may vary from person to person, but if your hair (and scalp) are healthy, your hair should and will grow each month.
On average, hair grows about half an inch per month. So, in two weeks, you can expect your hair to grow about one-quarter of an inch or half a centimetre every two weeks.
Caucasians Lose The Most Hair
In terms of which ethnicity tends to experience the most hair loss, Caucasians are the undisputed leaders.
Genetics (which controls ethnicity) is the number one cause of hair loss. 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.
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. Black hair contains a large amount of eumelanin pigmentation, a type of melanin.
While no two heads of hair are the same, there are three main classifications of hair type based on race Asian hair, Afro hair and Caucasian hair (which can also be referred to as European hair).
Yes, only 11% of the population have curly hair.
Hair can stop growing or grow slowly for a variety of reasons including age, genetics, hormones, or stress. You may notice your hair stops growing in one spot or seems to be growing slowly on one side. There are plenty of treatment options for slow-growing hair, including: medication.
While ladder-length hair is out of reach for most people, there's no set point at which all hair stops growing. Instead, hair growth is the complex product of genetics, health, care, and even seasonal changes.
As long as the hair follicles are still functioning, almost everyone can grow hair, but the speed varies from person to person. Healthy, growing hair depends on several factors, many of which we can't control, but some that we can. So, if you're looking for how to grow long hair, these are the top tips to take away…
How Much Can Hair Grow in a Month? "The scalp hair grows at about 1/3 to 1/2 inch per month on average, so about four to six inches per year for the hair on your head," says Vasiloudes. Of course, there are a few factors at play that can affect that number.
