25 stop growth??

I’m 22 year old male…
I was told that hormonal changes don’t finish till 25 years old… so does this mean I should expect more hair growth till then… and if so, will getting lasered now be a waste of time in the permanent scale?

Actually, hormonal changes can last far longer than that. It will vary from person to person.

Getting lasered now would not be a waste of time. The hair is going to remain there, it probably won’t go away by itself. If you wait too long, it will turn white or grey, and then the laser cannot treat it.
