1. Why this matters to you

When you sit in a salon chair, you're trusting a professional with your health. Understanding the basics of product shelf life & storage helps you make informed choices about where you get your hair done.

Tools sterilised between clients (sealed pouches or UV cabinet)
Clean towels for every client
Patch test offered before colour services
Product ingredient information available on request
Staff wearing gloves during chemical services

3. Questions to ask your stylist

How do you sterilise your tools between clients?
Do you offer a 48-hour patch test before colour?
Can I see the product ingredient list / SDS?
What's your protocol if I have a reaction?
How often do you change your towels?
