Sorry, Esprit, I must not have explained it too well in my post. I've never used Mane, only Prothik, but I just imagine they are pretty much the same type of thing.
They do work, and can look pretty good, especially with one of the "paint-on" concealers like Dermmatch underneath. But like I said, they are very messy. Too messy for me anymore.
I don't get "holes", but then I sleep on a narrow pillow, where the part of my hair that has the concealers in doesn't touch the pillow very much, if at all.
Yes, I would recommend trying Dermmatch with your fibers. That is what I use - Dermmatch and Toppik(using the spray maximizer). It works really well for the amount of baldness I have, which is considerable. I put Dermmatch on first(some on the scalp and some on the hair itself, then comb that through. Spray on a little hairspray, then spray on some Toppik. I usually comb that once or twice too, then I add Toppik until it looks full, and then spray on some more hairspray, and I am done. Of course, my front hairline takes a little more time since I have to get it just right because of my stupid transplants there, but sometimes that goes pretty good as well.
