Does human hair stop growing at some point if you let it grow out?

Question

It doesn't make evolutionary sense to me that human hair on the head wouldn't stop growing if you let it.

Answer 1

I learned about hair growth because my daughter used to cut hers when she walked on it.

Each individual follicle (I think that's the name of the little holes a hair comes out of) has its won growth cycle. A follicle continues to grow its single hair until its time to rest, which is usually around 6 months for an average person. That produced hair length down around your shoulder blades.

Then, after its six months of growth, that follicle stops to rest, and the hair falls out.

After a rest, the new hair grows out of that follicle, for the full six months.

Different people have different genetic rest cycles. I know women whose hair grows to their waist, which is about a year cycle.

My daughter, well, we never did know how long hers would grown, because when she walked on her hair, she had to cut it, which takes around 4 years to grow that long. Let me add the day she was born the nurses put a bow in her hair.

She has ancestry from India. Guiness Book of Records says the longest hair ever recorded was around 27 feet long, one of those guys in India who doesn't go anywhere or do anything, just sits under a tree and hopes it doesn't rain, and takes money from the devout. It was apparent his follicles never rest.

My daughter now as an adult keeps her hair cut short, but from time to time will let it grow down to her waist. There is a program which takes donated hair and it goes to make wigs for kids with cancer whose hair fell out. So, if it gets a little longer, she says to heck with it, waits a few more months, and tells the beautician to cut it for donation. The beauticians all know about the program, and her hair is so perfect and heavy they really rave when they see it.

As I said, I know about hair growth.

Answer 2

If you're talking about beards and stuff it doesn't stop growing, it instead slows down. Hence "breaking it in", or men with facial hair in their 20's are more likely to have shorter beards than men in their 50's although everyones' hair grows in very fast after it has been shaved, Naired, or otherwise removed.

I also have experience with this from having to shave myself and going for a month without shaving this past summer. Quite interesting how hair comes out like water out of a faucet on high when it's first growing in but then it slows down dramatically like a slow drip out of the same faucet.

Answer 3

It doesn't stop growing when you cut it, so why would it stop if you let it grow? There is nothing stopping the growth. An object in motion stays in motion, unless acted upon by an equal and opposite force.

Answer 4

My hair person tells me that as it gets longer it becomes more difficult to care for and neglect meakes it break off giving the illusion it has stopped growing. With proper conditioning and such it will continue to grow.

Answer 5

Hair loss affects both men and women. Here are some natural remedies that can help boost hair growth: https://bitly.im/aL92l While genetics plays a role, there are other factors, including: hormonal imbalances, an underactive thyroid gland, nutrient deficiencies and insufficient scalp circulation.

Answer 6

I think it does. It doesn't make sense to me either. I use to have real long hair down below my waist I cut it up to my shoulders and now it doesn't seem to want to get any longer than my shoulders.

Answer 7
