Sublime,
You may consider yourself at age 30 more fortunate as a Norwood 1.5 with visibile diffusing into a 2.5 class. There are many younger men in their late teens and early twenties who have progressed past that point already. In alot of cases of male pattern baldness, the earlier hairloss starts (teens) the more potential there usually is for hitting the advanced classes of 6 & 7 in one's lifetime. That is why you will hear veterans like myself often recommend to the younger guys to wait on doing a hair transplant to get a better gauge on where their hairloss is ultimately heading. And obviously considering one's family history of male pattern baldness would be prudent as well. As long as donor is limited any patient should consider their limited donor supply in contrast to their ultimate genetic loss in their "life-time". In simple terms, "there is never enough to restore everything" or at least until cloning, hair multiplication, etc becomes a reality. So until that time any patient needs to think in terms of where the limited donor will be allocated and exactly what level of density.
Then there are individuals like yourself who do not start losing their hair until their thirties. My guess would be that if you are seeing evidence of diffusing at 30 you probably noticed some minor hairloss in your mid-to-late 20s? Only now it may be more noticable. Why? Because male pattern baldness is progressive as we age. Remember, genetic hairloss can appear to slow down or what some claim has stopped altogethor but they base that on what they see in the mirror day-to-day. But male pattern baldness never stops dead in its tracks unless of course the individual's life itself should end. Every now and then you will read of a younger male patient who tries Propecia with great success and exclaims "my hairloss has been cured" or "Propecia stopped my hairloss!" but that's simply not true. Some of the FDA approved meds may "slow down" genetic hairloss but there are NO MEDS that cure male pattern baldness or stop it altogethor.
So you see there is really no specific rule of age when one should or should not attain a hair transplant procedure. It is more a matter of each patients' individual situation, the extent of their respective hairloss and what medicinal success they have achieved. Is this patient even a candidate for the procedure based on their goals, their donor resources, and their hair characteristics? Every week and sometimes every day somebody will tell me that they desire a "full head of hair" and will accept nothing short of it and yet they have family history of Norwood 6 & 7's in their family histories. DON"T DO IT!! is what I tell them. Because once you start surgical hair restoration, you are committed to it the rest of your life!
Now that leads up to the next point. You mentioned your desire to fill in some of the areas adjoining your existing hairline and behind it near the temporal lobe areas you are noticing diffusing into a Norwood 2.5 class. If you do start in that area, be prepared to experience shockloss all around the recipient area. I am not saying it will happen for sure but odds are you will have some level of shockloss in the diffused area and "it mat not ever grow back again". At that point you are then committed to keep filling in behind those areas with more surgery, see what I mean?
So listen my friend, you and only you can decide for yourself if you want a hair transplant to enhance your appearance. No one ever NEEDS a hair transplant and a hair transplant will never cure one's hairloss. But after doing much research, considering one's own limitations, and then utilize some life-time prudent planning, yes I think one can successfully enhance their appearance with realistic goals. At best one can achieve a good illusion of coverage and at the more conservative end of the spectrum, at least no longer look bald!
One last thing. If you do decide to move ahead, possibly consider a "small" FUE procedure with a proven FUE surgeon. Try to not do a large session or in other words try to not "fill in everything" in one procedure. Best wishes.
