There are no musts in natural hair.

Does it work for you? Use it/Do it.

Despite what many of the natural hair elite espouse daily, nothing is set in stone. You don't have to protective style. You don't have to have a 20 step 2 day care process. Natural hair can be as simple or as involved as you want it to be. The only thing that is required is to cleanse/condition/detangle/style on a semi regular basis. Beyond that do whatever works for your lifestyle/length goals/style preferences/patience level regardless of what the internet (me included) tells you.
