Can genetic hair loss reverse?

I’ve noticed some hair loss at the temples when I was about 17/18 and 3 years later it’s basically at the same level. Haven’t noticed thinning, hair at crown/on top is still fine. Is it possible for someone to lose a little bit of hair and for the balding to then stop for a (longer) period of time? Or will you always continue to lose hair, albeit it being at a slower rate? Cause if there is a chance my hair stays the way it is right now, I might be interested in a HT with +/-650 grafts to fix my hairline at the temples.

Bonus question: My hair at my temples was blonde, born that way. Rest of the head had brown hair. Is there any chance that that blonde hair might have been more easier affected by hair loss? Or just a coincidence?

Genetic balding is a progressive process that may stop when you achieve your inherited hair loss pattern but it can be reversed in younger men, sometimes for years but sooner or later a person with genetic balding will reach his final inherited pattern of balding.  The different hair colors have nothing to do with what is happening to you.
