My kids have super thick hair. The boys have curly super thick hair. All 3 have eczema and have scalp sores from time to time. With thank you esp, getting him to really clean his hair/scalp can be tough. the problems with hand coordination (his fingers don't bend the way most people's do, no one knows why but Wiz does it too) don't help this AT ALL. I stopped coloring my hair years ago because scalp problems but kept this bottle for applying color to the roots. Just recently thank you's scalp was a super mess and he was having fits getting it washed and getting the medications on his scalp instead of his hair so I pulled the bottle out. This bottle has a top with 5 fingers that the contents can come out of and it is designed to put hair color on your roots only. WOW did it make a big difference. We put the normal amt of shampoo in the bottle, diluted it with warm water, and then used it on his hair. Soap got all the way to the skin, it didn't hurt the way it normally would to get it there through the thicket of hair, and he actually enjoyed the experience (a first since before he was crawling). I thought I would post here because I know hygeine can be a big issue with our kiddos. You do have to rinse the bottle well to make sure nothing clogs the fingers, but if they get clogged a paper clip or pin can open it up. I have used the same bottle for five or six years.
