Is there any way whatsoever to determine whether a person will at some point in their lives suffer from male pattern baldness, and if so, would this not eliminate the problem of transplanting people too young (say if they have a naturally high/ uneven hairline etc)
There is a test called HairDX that will tell you if you have the gene (70% accurate), but it won’t tell you when that gene will be expressed… or if it will be expressed at all. So on a predictive basis, the answer is unfortunately no. But if you want to know if you are balding (possibly just a little) then you should see a doctor who is experienced in hair analysis for miniaturization and hair bulk, which this will tell you if the balding process has started in you.
Many young men with a balding dad or uncle or brother are expecting hair loss to happen to them, and these are the patients I can help by telling them what, if anything, is going on in their head. If you have an average hair thickness, you might not see thinning until the hair loss is at 50% of the original density. Coarser haired men will often not detect loss even at 60-70% of their original density and blond men may not detect hair loss or thinning to 80-90% of the hair due to the low contrast between hair and skin color.
