Average Time from Start of MPB Until It’s Noticeable?

Hello Dr.Rassman!

My question: When MPB starts, how long does it usually take for the hair loss to become noticeable? I am starting to lose hair/thin (only visible by me) and with MPB in my genes on both sides of the family, I am curious how long it will take for it to become apparent.

I’m sure there’s no exact answer for my question, but I assume there is an average time frame.

Thank you!

Male pattern baldness (MPB) can start with the onset of puberty, but it is not usually socially noticeable until more than 50% of your original hairs fall out. This can take many years. In general, for those who go completely bald (Norwood class 6 or 7 — see image at right) it can take 5 to 10 years, but there are always exceptions. For some men it can take 20 to even 30 years.

There is no general time frame that fits everyone. Maybe you should ask your family members who have MPB how long it took them to notice their hair loss.
