DD is 13 and wants to shape her eyebrows for first time. They are straight and quite dark but not 'bushy' or mono brow. 
I have offered to pay for them to be done at her hairdresser but she says this would be embarrassing
and she wants me to pluck them for her.
I really dont want to mess them up - i had mono brow tendancy in my youth and plucked mine to thin line (was the 80's!) Dont want to do this to her also can imagine her hitting ceiling at first 'pluck' and that being end of it. (i just pluck odd stays from mine everyday so is just maintainace for me)
Any tips - what is current method of choice?
