Telling minaturization from regrowth.

[auglen]

Basically all I want to ask is in the topic - is there any good way of distinguishing miniaturizing hair from regrowth?

I do imagine that most of you just know your hairlines very well so that you can tell if there's new hair.
Well I'm only eighteen, always had have very thin hair and never had a perfect hairline. As my brother's hairline has already receded to something like NW2 when he was 21 I'm obiviously worried about myself.

I think my temples might be getting deeper, especially since it looks like my left temple is deeper than the right one, so I guess it's a sign that something is going on.
There are some short hairs on that left temple (easy to spot as I have pretty long hair), not super short, say a little more than an inch long.
There are some along the hairline too, but very very few and some more on my right temple but not as much as on the left temple.

Now if we could hold everything constant then I'd be sure it's balding, but in the last 6 months I changed my diet pretty dramatically to a relatively healthy one, started taking a multivitamin (never had).
Also stopped any masturbation (which equals no sexual activity anymore), no, not for my hair, just didn't feel like doing it anymore. Lost any urge within just a few weeks so don't think I'm doing some kind of a big sacrafice .

I think I will jump on propecia+minox anyways, especially that I couldn't be bothered even if I was to be sexually dysfunctional forever, but still would love if I could do without it.
