I was a punk in the late 70s and regularly wore a mohawk. Now I’m bald. There may or may not be a causal relationship between these events.
I had a big tall mohawk in high school and have thick curly hair now.
As my mom always said, “It’s just hair, if you damage it you can shave your head and it will grow back” .
Backcombing, teasing hair like that is damaging yes, but hair is dead, it’s like the white part of fingernails. Unless you damage the actual root (like a bad burn to the scalp) it will always grow back.
There are hairstyles that can do damage to the follicles to the point they can’t grow hair anymore. It’s called traction alopecia, the thing that Will Smith’s wife has.
When did you start noticing the fallout from that? Have you trier finasteride+minoxidil to remedy it?
