Re: MUA Hygiene Practices: Advice Requested...
That sounds very unprofessional of the makeup artist.
Most good artist have several brushes when they are working on more than one person during a booking.
I attended a wedding over the weekend wher the MUA had several brushes and where she needed to use the same brush she cleaned it with a makeup cleanser wipe before using it on the next person.
I'm sure most artist won't mind if you buy your own brushes, just ask the which ones you will need and the make , (usually MAC).
