I wash my hair weekly. I twist the roots everytime I wash, and I sleep with a bandana on. The whole process takes about 5-6 hours. Sometimes I don't have the time to twist it, so I just wash it.
How frequently are you guys washing your hair? If you aren't washing, why not (legitimate fears)? I must preface this by saying in big letters PLEASE DON'T TAKE OFFENSE but: It seems like most of the posters here are caucasian. I'm sure that the texture of my hair is the reason I have different results, but I've never considered NOT washing my hair. It seems like a lot of posters' issues are with the dreads coming loose with washing?
I'm also wondering if you are using a lot of products, which can sometimes have an adverse affect over time.
Again, no offense offered, I am curious and a bit naive, that's all. :)
