Booked a hairstylist

Hello everybody! My wedding is next month and I have my hair thinning. It's not that bad but harsh light can show the scalp from front and n can't style it. I have booked a hairstylist (jodhpur, india). My wedding near my town in rajasthan... Any tips you all can give me ? This is the first time I have kept a hairstylist and also was thinking to use hair fibres in affected areas
