According to the U.S Center for Disease Control (CDC), scalp hair grows at an average rate of 0.50 inches (1.25 cm) per month, or one-eighth of an inch every week. This means the average person grows 6 inches of hair per year.
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.
How fast does hair grow? It's hard to say exactly how fast your hair grows — everyone is different! — but on average, hair grows about half an inch over the course of a month. That being said, it's not unusual for hair to grow as little as a centimeter or as much as an inch in a month.
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.
On average, hair tends to grow between 0.5 and 1.7 centimeters per month. This is equivalent to around 0.2 to 0.7 inches.
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.

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.
“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.
After haircut
According to the American Society of Dermatology, after a hair cut in an average healthy person, it is usually a month to regrow your hair back by half an inch. If you are a female and lost inches of hair in a haircut, remember it takes almost a year to regrow about six inches of new hair.
Hair grows about 1cm a month. You cannot make your hair grow 5 inches in one week. That is not possible. Hair grows about 1cm a month.
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.
Hair will continue to grow right away and you might start seeing stubble within a day or two.

What time of day does hair grow the fastest? 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 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.
