Why does the fur of animals stop growing/shed past a certain length but we have to manually cut our own hairs?
In: Biology
So apparently, it isn’t dependent on length, but sheds after a hair growth cycle between 2-4 years. TIL
My facial fur has a max length and a max amount that will grow, and it’s depressingly little for each…
There are certain animals that also run into this problem. Golden retrievers and some sheep.
You don’t have to cut your hair, you cut it for cosmetic appearance. There is a “critical mass” for you hair length and it is different for everyone. So unless you are taking especially good care of your hair, you will notice at some point it will affectively just stall in growth length. And either fallout normally or break off.
Hair length = growth rate x hair life
So long hair on body either grow fast, or live longer, or both. Short ones, the opposite.
Sometimes you end up with the wrong follicle in the wrong place, like I have a single eyebrow hair that grows like head hair and I gotta trim Joey every week.
