Vitamins B and D factor big in healthy hair. So do zinc, omega-3 fatty acids, and the B vitamin biotin. Your doctor can test you for deficiencies. Ask them whether you should take a multivitamin or supplement and how much.
"Getting a trim every six to eight weeks prevents split ends and damage, making ends stronger and leading to faster growth," she explains. "I recommend trimming 1 to 2 inches at each appointment to avoid fraying ends and keep hair healthy."
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.
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.
Hair grows about 1/2 inch per month on average , So it will take 2years for 12 inches.
Most hair strands grow at an average rate of about 0.3 to 0.4 mm a day. So, this means it may grow up to one-tenth of an inch or a little more in a week. However, this growth differs with people. Genetics, hormones, nutrition, and stress levels all play a role when it comes to the health and growth of tresses.
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.
A half-inch per month means you could grow about 6 inches of healthy hair per year. However, this figure is simply the average growth rate, with some people naturally growing hair more quickly and others more slowly. Many factors can impact your hair growth rate, including: Hair growth cycles.
The way that sleep affects your body's natural hormones is probably the most important part of preventing hair loss. Your body produces a hormone called melatonin. This hormone helps your body regulate your sleep cycle, and it also has been shown to increase hair growth.
But since your metabolism slows down at night, so does your hair growth, explains Waldman. Goddard adds that the primetime hair growing hours are between 10-11 a.m. and 2-4 p.m.
How long does it take to grow long hair? According to the CDC, scalp hair grows an average of one-half inch per month. If your hair is two inches long and you're aiming for shoulder length (about 12 inches) growth, that adds up to a little less than two years to reach your goal.
“Other than age, hair can grow slower due to health conditions, vitamin or nutrient deficiencies caused by a poor diet, stress, hormonal imbalances, certain medications and even excessive heat damage from everyday styling,” explains Pierre.
“Hair tends to grow a little faster in summer and slower in winter,” said Dr. Alan Parks, board-certified dermatologist and founder of DermWarehouse. “An underactive thyroid can also slow down hair growth.”
Age: Hair grows fastest between the ages of 15 and 30, before slowing down. Some follicles stop working altogether as people get older. This is why some people get thinner hair or go bald.
How Does Hair Grow? The average rate of hair growth is between 0.3 and 0.4 millimeters per day, or between 0.5 and 1.7 centimeters per month, or roughly 6 inches per year. Everyone's hair is unique and a variety of factors can affect how quickly it grows.
Pulling out hairs actually can induce them to grow back, along with up to five times as many new hairs in the surrounding area, according to tests done on rats.
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. Your strands will look better, feel better, and be healthier, too.

Biotin, also known as vitamin B7, stimulates keratin production in hair and can increase the rate of follicle growth.
How Fast Does Hair Grow? According to the American Academy of Dermatology, your hair grows at a rate of approximately six inches per year, or about half an inch per month. This means that over the course of six months, you can expect the hair on your head to grow by approximately three inches.
Ignoring these perceptual differences, human hair grows at a fairly consistent rate of about half a millimeter per day, or about half an inch each month (more specifically, the study says hair grows at 0.44 mm per day). Depending on your age, hair may grow faster or slower.
For most women, this occurs sometime between the ages of 44 and 55. When your ovaries stop producing estrogen and progesterone—two hormones key to menstruating—this is when you go into menopause. Estrogen and progesterone also happen to be linked to your hair's health, including its growth.
