I do mini trims on my hair all the time when needed. I find it really easy, I'm good at it and it saves money. Make sure you invest in a pair of barber shears, they are only about $5, very well worth it if you are going to try and cut your own hair, plus being able to avoid constant split ends from using non-hair cutting scissors.
Sunny is 3c/4a.

Currently using Jessicurl Too Shea conditioner with honey, RR mixed with CC, pure shea butter or Elasta QP mango butter on ends of hair.
