Rollers – These can be used to roll the hair and air dry or coupled with the hooded/soft bonnet dryer for roller sets. Roller sets tend to be the healthiest hair of drying relaxed hair after a wash as they give you smooth straight hair with a bit of body but most importantly they also avoid high heat that leads to breakage.
I think a must-have for really curly, and thick, hair is the karmin g3 straightener. I have 3B hair and it leaves it pin-straight and shiny!
