In my experience you have a good time to look forward to. I can tell you what happened with me starting from almost bald NW5/6. I had hairloss for a good 20 years+ with aggressive hair loss in the last decade. My hair loss was diffuse, i.e. miniaturisation and further minitiarisation and further miniaturisation. I have been on Big3 for last 14 months with unimaginable results. I have literally got my life back from nothing. Something I never imagined could happen. Extremely lucky to be such a responder.
0-4 months, vellus on temples and crown, tiny hair on top but nothing major or noticable.
At about 6 months, temples on vellus, crown growing tiny hair, rest picking up that I could get a cm or so haircut. Also got people noticing.
10 months, temples still struggling with vellus but a few miniscule hair start showing up in between. Crown starting to fill up and 'the hole' shrinking. Top good noticable hair. I had a frame. Top hair still thinner and much slower growing than non male pattern baldness sides.
12-14 months, temples start showing more length but still majority miniature and non-cosmetic. Crown filling up nicely. Rest of top looks full ecept they are much thinner and slower growing than non male pattern baldness sides.
Now I am at 14 months and I have pretty much won the battle for top and crown. Its still getting denser, thicker and better every month. Temples is my last frontier and are now coming forward slowly and randomly.
To give you an idea, I shaved my head at 10 months so in last 4 months:
Non-male pattern baldness would have grown 2-4 inches
Top has grown about 1-1.5 inches
Temples have range from 1-2 mm to 0.5 inch
Hair thickness and density seems to be proportional to the rate of growth, so male pattern baldness top about half thick of normal, temples still v thin.
It is getting better everywhere every month.
Temples seem to grow randomly, i.e. some random patches will show hair and will grow outwards and forwards. Think about how the patch looks in the first few days and weeks after you throw grass seeds.
