How to Talk to Your Stylist (Beginner-Friendly Guide)

Knowing the terms is helpful, but using them correctly matters more.

Here’s how to make sure you actually get the result you want:

• Bring 2–3 reference photos (and one you don’t like)
• Be clear about your goal: volume, length, low maintenance, or color change
• Mention your natural texture and routine
• Ask about maintenance before committing

This avoids confusion and helps your stylist adjust the look to suit you.
