Going natural is a process, so of course you will need items to make your journey easier. Some items I would suggest are:
Natural Oils coconut, jojoba, shea butter, and olive oil
Hair Rollers/Perm Rods
Metal Free Hair Elastics
Wide Tooth Comb
Silk or Satin Scarf, Bonnet, and/or Pillowcase
If there's anything else that you have found useful while transitioning feel free to comment.
