Here are some photos i took today. I have quite a large circle of very thin hair. It's just the top hemisphere that bothers me, the bottom half can be camouflaged by buzzing back and sides. Does Seti actually grow or thicken existing hair? As you can see my thin parts actually have decent coverage it's just so damn thin. My crown/vertex has been like this for several years. Toppik works great but i'm fed up of that. I had a couple of online consultations on the strength of similar photos and apparently i have retrograde alopecia (thinning out neckline) which means i don't have enough donor area. I'm only looking for a modest improvement.
