I'm pretty much bald, and have been tending that way since my mid twenties. Early thirties now. I'm plenty happy.

If you feel like your happiness is dependent on your having hair, then you should probably really ask yourself why.

If you feel like having less hair makes you less attractive, then I can tell you I've had loads of hair and now none of it, and I've met women that love or hate both.

Own it.

A few of my friends started going bald in their early 20s... whoops

There aer treatments for hair loss that can slow but not reverse progression of baldness. "Don't go bald" is actionable.

Treatments that can have seriously adverse side effects for some individuals or simply not work at all for others. Furthermore, most of the treatments do exactly what you said: they slow the progression, not halt it. It's not so black and white, unfortunately.

"Don't care about going bald" is even better.

Or "don't tie your self worth or happiness to your appearance," to be more general.

Yes, and I’m trying to call China now, but apparently the Chinese food delivery guy found a friend...

Maybe the advice should have been posted for 20 year olds and not 34 year olds. It’s still not helpful as is.

There are also surgical robots (Restoration Robotics) that do hair transplants without leaving ugly scars.
