hopefully I can shed some light.
when I was 26, I began to see my hairline and temples recede (I'm 32 now.)
I jumped on Propecia right away, and took 2 prescriptions at 3 months each.
The recession never progressed, so I just stopped taking the medication because it was so expensive, I wasn't losing any hair, and I wanted to have a baby so I had to get off of it. Take no chances with something like that. The drug companies will tell you whatever they want in order for you to buy their product.
Now, 6 years later, my hair has remained the same- and, I haven't taken any propecia in over 5 years.
I had a very low hairline in highschool, so I lost about 1/2" off my hairline and temples. And it has never worsened. I don't have a thin hairline and my temples are not receded any more than they already have.
In my position, I'm not even a 1.5
BUT- my point is--
when you guys hit your late 20-s early 30s, it's going to be normal to lose a bit around your hairline and temples- 80% of guys without male pattern baldness (or so it seems) go through this. It can happen at any point, though.
The thing to remember is that male pattern baldness has absolutely NO typical pattern- it can hit at any age and hit in any way- it's totally unpredictable.
And, a little hairloss doesn NOT mean you're gonna go bald
I know guys in their late-40s early 50s who have had small bald spots for over 10 years and it never got worse- it's barely noticeable.
And, in my case, I began to recede slightly in my mid/late 20s and it just stopped overnight. No one on the planet will say I'm losing any hair, well, because I'm not.
But, but like the rest of you chaps, I had a scare and went on the medication.
That was stupid, because I really don't see that stuff working for the long run. You can delay it, but so what- you're still gonna go bald if you're gonna go bald, so why bother.
My point is-
if you guys notice slight thinning or recession, forget about it-- it doesn't mean you're going bald necessarily. Doesn't matter if your Dad was bald or your 14th distant cousin's brtoher's son was bald, it's just random.
Wait it out and don't go on medication until you're positive you're suffering from male pattern baldness.
Because if you go on it ahead of time, you're in for a wallet-drainign experience and not to mention, your health will be at serious risk- maybe not right now, but no one knows what's gonna happen to propecia users in 15 or 20 years from now.
Don't risk your life over it. You live one time only.
Oh, and by the way- you know how you guys spend so much time looking at everyone else's hairline???
Trust me on this- that's just a phase, and will pass- believe me- when you hit my age, the last thing you will ever care about is some other guy's hairline and it's the last thing you'll pay attention to.
