DanceComp lists all the attending vendors of the event. You will see the few hair and make up vendors there and have access to their contact information. 

Thank you Frederic but so far there is no attending vendor its still empty wondering any recommendations ?

Open this link the Vendors should show. I noticed a problem on the iphone app where the official, judges and vendors don’t show.

Hello dear, we have several vendors for hair and make up – Lashes and brushes, Olga Blinove, Alante -Alan and Nathan and others. All are listed on the website under vendors page
