1. When people say "Wash your hair around once a week," I'm assuming people take more than one shower a week. So by washing do you mean "with shampoo" or do you mean getting them wet at all? If you take 4 showers a week and only wash your dreads fully one of those 4 times, the other 3 times do you just get them wet, or completely cover them in a showercap?
2. How do you dry dreads? I'd imagine if you rubbed a towel all over them they'd get towel fuzzies stuck all up in them. And if you let them airdry, wouldn't they be dripping wet all over the place and take hours to dry?
