This can be either an update to the Sims 4 spa game pack or game pack of its own
So I’ve been thinking because I love the nail update and how you can use the massage chair and pedicure feature. I think it would be even better if players had the ability to build a salon. Make it to where you can get your sims hair styled, make a shampoo hair washing sink/counter for build mode, vanity mirror with lights, a hair dryer chair that sims sit under. You can create a new skill for sims to learn how to become a hairstylist. New decor and clutter items like a blow dryer, hair spray, shampoo bottles, towels, flat irons, brushes, combs, hair accessories, hand mirrors, even hair clippings on the floor. Sims can get the ends of their hair colored or streaks. You can have sims offer up services online like they do with the pedicure chair instead it will be a styling chair. Also for the spa day update maybe also include the ability for sims to get wax treatments legs, face, etc.
