Check the prep instructions before washing your hair
Mayssa's Beauty Mark in Kenilworth asks curly-cut clients to arrive with clean, product-free, fully detangled and completely dry hair in its natural form. Its FAQ also directs clients to call with questions. These are this salon's appointment instructions, not a universal rule for every curl service.
Read the confirmation before your wash day, not on the drive over. If your usual routine needs product to keep curls defined, ask the salon what it wants you to do. For salon teams, put preparation instructions in the booking confirmation so clients do not have to hunt through the website.
