Help! Save My Dreads
There is absolutely nothing wrong with getting them wet. You should probably wash them if that's the only time they've been wet in 10 days.
It's good for them. Your dreads might get poofy. They might fall apart. But that's what they have to do in order to dread. And in order to do that your hair has to be clean. Greasy/dirty hair won't dread nearly as fast as clean hair.
SO get it wet. Wash it. Go swimming. Jump in a sprinkler. Have a water fight. Live life.
Just make sure to let your hair dry in between washings/wettings. Your dreads are new so you likely won't have too much to worry about in that department.
Do not waste time taking out your dreads and re backcombing. That's pointless. You have to go through this stage. We all do. The only way to put it off is to crochet and wax. And that will just make things worse in the long run.
