I love MAC!
I try to get my eyebrows threaded and if I'm not able to do so then wax it is.
I do my shopping at ULTA .. love this place.
When my daughters were 12ish.. I took them in for their first eyebrow wax and then we went to Merle Norman. They were taught how to put on makeup (at that age it was mascara and lip gloss) and how to care for their skin.
Your never too young to learn how to care for your skin or your eyebrows!
