Ashley Graham's Hairstylist Shares 11 On-Set Must Haves

GHD Chronos Styler ($329)

Marjan recommends the GHD Styler because it "styles the hair so much faster, makes the hair shinier, and has no extreme heat damage, which is so important to me and my clients." Our editor tried it and felt similarly, writing in her GHD Chronos review that "it features fancy-sounding HD motion-response technology that adapts to your movements, so you're able to get your desired style with just one stroke." The iron heats up to 365 degrees in 20 seconds and switches off automatically after 10 minutes of inactivity.
