Lint or build up?
It's a tea tree shampoo from sprouts, Avalon organics. I forgot I also use the olive oil shampoo from the ethnic section when my scalp feels dry. But mostly I use the tea tree one. I tried the baking soda, rosemary, tea tree and lavender mix, but my dandruff got worse. I sleep with a tam on because my hair gets crazy if I sleep without it. It also keeps my hair out of my face. My dreads are short now that they shrank up. It's more comfortable to have a hat when I sleep.
