If you have ever gotten a shorter-than-you-wanted hair cut or you just want to join in on the bushy beard trend, you might find yourself wondering - just how fast does hair grow?
In this article, we will break down the average hair growth rates per day, hair growth rates per month, and how the rates vary depending on what hair we are talking about.
If we are talking about the hair on the top of your head, the average hair growth you can expect to see in a day is about 0.34-0.36mm per day.
So, if we consider that an average credit card width is about 1 millimeter, your daily hair growth is about ⅓ the thickness of a credit card.
These numbers are an average, and your personal hair growth rates will vary based on your age, gender, hair color, and ethnicity.
The average amount you can expect your scalp hair to grow per month is about 1cm, or about the width of a pea.
So, if you have pretty average hair growth, you can expect about 4.72 inches of new growth a year.
But, there can be large variations from person to person, with one study reporting monthly hair growth rates ranging from 0.6cm - 3.36cm per month!
If you want to know just how fast you can grow your beard out, you are probably looking at a slightly faster average growth rate than your scalp hair.
Beard hair can be expected to grow about 0.38mm per day, just slightly over ⅓ the width of a credit card.
There may even be a seasonal variation in how fast your beard grows.
One study in 14 caucasian men reported that beard growth was the slowest in January and February, with a gradual 60% growth increase and peak from March to July.
Eyelash and eyebrow hair is the slowest growing hair on your face, compared to beard or scalp hair.
Eyelash and eyebrow hairs can be expected to grow about 0.16mm per day, or about half as fast as your scalp hair.
So, make sure you like what your beautician is doing with those brows - you may have to put up with it for a while.
