If you are 4a or 4b, then 9 times out of ten you are definitely going to need some sort of moisture, especially on the ends. When I get a doobie, I oil the scalp with Hollywood Carrot Oil Creme every other day and everytime I wrap the hair up or comb it down, I use Hollywood Carrot Oil or Taalijah Wahid Oil on the ends of the hair (usually once in the morning, and once before bed).
