Hair cleaning itself
Have you ever tried that thing where if you go for long enough without washing your hair it cleans itself? My friend did, and hers looks great. She says it takes a few weeks.
Benefits: saves time in the shower, saves money on shampoo, might be healthier, definitely better for the environment.
Costs: you have to look (and feel) filthy for a few weeks (with associated costs).
I hate being dirty, especially having dirty hair. It makes me feel like my brain is swimming in grease and I can't think properly. I feel like a different person after I take a shower if I was really dirty. So this would be hard for me, but I am intrigued by the naturalness of it and the fact that our prehistoric ancestors probably never washed their hair and it might have looked fine.
I started trying it, but after 3 or 4 days I have to relent. I thought I could cheat a little by putting powder in my hair (and wearing it up) to make it not look dirty, but it in fact does not resemble clean at all. (Probably because I have really thin, fine hair.) I have to go to work and school, and I don't want to go out in public looking dirty. I wonder when a person would have the time to do such a thing? When would someone have the opportunity to not go out in public for weeks? Someone without a job who doesn't go to school, I guess.
Have any of you tried it? If so, what was your experience, and how long did it take?
I'm sure this would vary a lot by hair texture as well.
Edit: Actually, I just took my hair down, and it does look almost clean. So I could probably go another day at least. But I don't want to right now.
