hello tranzept, after going to a hairloss specialist, he told me many things, two of which were very important to my understanding of hairloss, he told me that each follicle of hair has its own vein, whenever that vein closes off from the follicle the hair bulb is dead (which causes the hair to fall out), meaning its chance of being regrown are extremely slim, now the hair itself can be lost without the bulb dying, the reason being, the hair bulb, even if blood vein closes off, can still get what it needs from surrounding veins from other follicles
this translates to this, the more hair you have around "balding spots" gives you more of a chance to have regrowth (because the bulbs arent dead) ie the top of your head, the problem is, your forhead doesnt have hair surrounding it, making it alot more troublesome to regrow hair
at the end of my visit, he explained to me that hairloss requires patience and ultimately dont expect too much from your hairloss products, he told me there was a chance of regrowth although the more regrowth you expect the less likely you will acheive that, he said that you should be expect to stop your hairloss and keep what you've already got, anything extra you should consider a bonus
also, about minoxidil, obviously if you use minoxidil and propecia thats much better than using propecia by itself (because they fight hairloss in two seperate ways) but you have to take them both for life, and its much easier to take a pill for life than whipe chemicals in your hair two times a day which gives you scalp pains and itching, being 19 myself i say, take propecia and use nizoral and by the time you turn 29 hair cloning will be on the market and you will have saved yourself alot of agony
