Hair loss question

I personalyy have had thinning hair for the past 2-3 years and im only 20... One of my precautions to using any supp's is hairloss, The past couple years Ive kept my head shaved or my hair very short. Now my question is, do these supp's effect the hair follecule (sp?) itself? meaning no matter what, even if your is kept short or shaved the effect will take place.... or does it only happen when your hair is past the "safe" length?
I may want to grow my hair again in the near future, will this affect it?

i am not so sure there is a safe length LOL...what can use is topicals like azelic acid,minoxidle,rogaine,spiro cream or liquid, or some orals like propecia/finastride and a shampoo nizoral 2%...now if genetically your are predisposed to male pattern baldness these things will slow the process down..

but what are the effects of these products if say... your head is shaved? Would you even have to use these products in that case?

shaved as in bic'ed with a razor??? or buzzed? i mean i keep my hair damn short but still use a few of these products...i am pre-disposed to hair loss so i am just prolonging the inevitable..but when my hair grows out alittle i don't wanna look at it thinnin at a rapid pace....so the real question is do you accept the fact that your losing your hair or are you like me and in denial LOL and wanna stop it from falling out faster

ever since Ive shaved its been going pretty good.. And when I mean shaved im talking Mach3'ing it.

Should I still use those products on my bare head? Ofcourse the hair grows a ittle within a couple days and ill keep the stubbles for awhile too

I don't believe there is any "safe" length of hair, it probably just wouldn't be as noticable initially if it were long. The only "living" part of hair is the follicle and that is where damage is done (I believe it is in the DHT conversion). I don't think it happens to everyone, but those predisposed to male pattern baldness obviously have a much higher risk - probably because it's going to happen anyway, so it just speeds the process up. You say that you fit in to that category, so that is something you must consider. I believe the products above may slow the process, but yes, most likely just delaying the inevitable.

baldings a bitch...but if i stop most of it great.i thinlk that us men that are balding wait too long to do anythign about it intillwe have hair like bruce willis. anyways what are some hairstop products i can buy at walmart?
