In the Beauty Lab's permanent root touch-up products test, scientists dyed human hair samples in brown, red and blonde shades mixed with gray, then assessed initial gray hair coverage and shine using the Chromameter machine. Next, each dye's color retention was gauged by putting the dyed hair samples through 20 wash and dry cycles using the Swatch Wash Station and four hours of UVA light exposure with the Q-Lab QUV Accelerated Weathering Tester.

"If you permanently dye your hair a very dark colour, applying temporary dye on top won’t make much difference. Whereas, if your hair’s bleached or light blonde, you’ll see a real change." Temporary hair color, like L’Oréal Paris Colorista Hair Makeup Temporary 1-Day Hair Color Spray, is simply sprayed onto the hair to coat each strand with color so no bleach is required. Semi-permanent hair dye, like L’Oréal Paris Colorista Semi-Permanent Hair Color, is a non-damaging, short-term way to color your hair. Unlike most permanent formulas, it doesn’t contain ammonia or peroxide, which means it doesn’t require any developer or pre-mixing so you can apply it straight to your hair from the applicator. It generally lasts through a few washes and can go even longer if you use the right shampoo. And since there’s no bleach required, it’s also safe to use on hair that’s been permed or relaxed.

Root touch-ups have come a long way since older formulas that could look cakey, feel crusty or cover only a small area," Aral says. "The modern formulas look and feel more natural." Here, GH Beauty Lab and hair color pro guidelines for finding your ideal match: While application also varies for creams and dye drops, the majority instruct users to apply the colour to clean, towel-dried tresses. Alex’s top tip? "Detangle hair first – this will make application easier."

First off, using a temporary hair colour spray is a fun way to change up your appearance. These sprays give you the freedom to experiment with new colours without committing to a permanent change, whether you're looking to add a pop of colour to your hair for a special occasion or just want to try something new.

Many people may be hesitant to try out temporary color due to the fear of permanently altering their natural hair color, but colorist Joie Wallace assures that there is nothing to worry about.

Depending on the product, and how permanent it is, it may take longer for your hair to return to its natural color, but the temporary color will eventually fade and vanish nevertheless.
