does anyone know a way to where it will stay on if you scratch your head? im really surprised as to how well this stuff works,my hair is really thin,i use to buzz my head everyday,ive let it grow up for about a month now,no one can tell im using the dermmatch,when i scratch alil hard,some will come off,but not enough to where it comes off,just wanted to know if there was something so nothing would come on my figners..other than that,this stuff is awesome,ive swam with it,nothing comes out,nothing on my pillow after ive slept,nothing on my shirt,i can run my hand thru head and nothing,very surprised this stuff doesnt cost alot more,im using the black ..ive also tried toppik,for me toppik is a peice of crap,id figure toppik is only good for people who dont have too much hair loss,but still dont see why people would like it,that stuff comes off if you change shirts,or run your fingers or anything,so if anyone can let me know,thatd be great..dermmatch is a great product
