Ask for the treatment steps
Ask whether shampoo, conditioner, scalp cleansing, drying and styling are included, along with approximate time for each step. If you want a straightforward wash and blow-dry, ask specifically for that option.
Choose products and styling to suit you
Describe your fragrance preferences, usual hair-care routine and whether you want styling products. Ask in advance about supplements for long hair, special styling or extra conditioning.
Leave a buffer before dinner
If dinner or a rooftop bar follows, leave enough time for drying, finishing and travel. Compare the complete process and final price rather than relying on a package name.
