Not scheduling a makeup trial prior to your d-day, may lead to makeup hazards . Especially when one is not so used to makeup in the first place.
A make up trial gives the bride a feel of what she is to look like on her wedding day.

Hair Trial on the other hand, gives the stylist the opportunity to try out different styles to suit the brides face. Though you may have a style in mind, it just might not be a fit. Remember there is little time for trial and error.
