One of my friends in college said he never used shampoo. Thought that was weird, but I tried it. For a while, my hair felt greasier. After a couple of months, my scalp adjusted to it. Haven't used shampoo since.

Just clean it with water?
I almost tried that once and ai failed. My shampoo is running out so might be a good time to try again.
I only use shampoo after I go to the pool. Other than that, it’s only been water for two years. The first month was greasy, but after that, smooth sailing.
