Curly hair requires a special touch. I know first hand how hard it is to find someone who understands the importance of specific cutting and coloring techniques requires to address curly hair and its various textures. You could hire an Extensions Expert, with more and more clients are embracing extensions for length, volume or a fun touch of color, you would want someone with brand-specific training.
Kids cuts also require someone with a different skill-set. Obviously you have to love children and it require patience and a way of talking to them that calms them down.
You might also considering bringing in some other skills like brow or lash extension specialists or having a blow-out bar can be very helpful.
