I know there's no guarantees that I will experience any significant regrowth but thankfully I think I am currently riding out a shed on rogaine and am expecting a comeback. However, until that time my hair is looking very thin. My scalp is visible at my hairline and being 19 (and at university) it does tend to bother me, especially when trying to chat up girls, despite being a generally confident guy. Anyway, to hide this should I get some toppik or viviscal to cover my shed? It won't hinder or interfere with my progress/regrowth process in any way will it? Also, what's the chances of it falling out while I'm exercising etc? Thanks.
