Chalk up the bright, colorful streaks you’re seeing on models’ hair in the spring fashion mags to … chalk.

Hair chalking is exactly what it sounds like: temporarily coloring strands with the traditional artist tool. DIYers can find several products specifically for hair tinting, but Jacqueline Scordato — who owns J. Scordato Salon, 3854 E. Fort Lowell Road, 327-0407, — likes artist pastels because of the wide range of colors.

Scordato’s been offering the service for about a year and a half. It can range from $10-$30 depending on whether you want a few colored strands around your face or a more intense, all-over look.

“It’s really fun,” says Scordato, and it works on both blondes and brunettes.

Now’s the time for the carefree, music-festival-ready look. Expect a little bit of color transfer — “Stay away from white,” Scordato warns — and once your hair is washed, the color’s gone. If you’d like to hang onto the colorful ’do for more than a day, Scordato recommends loosely braiding hair before bed to help preserve the tint. For those who love the punchy, colorful flashes, John Mitchell’s Inkworks can provide semi-permanent color for about a month.

Here’s how Scordato created this colorful look on stylist Danielle Sweety.

Dampen hair before coloring. Scordato liberally sprayed Paul Mitchell Awapuhi Moisture Mist on Sweety’s hair before gently rubbing chalk on inch-wide sections. “If you’re not getting the color transfer,” she says, “it’s because it’s not wet enough.”

She used darker colors toward the top, lighter ones at the ends. “I love using yellow and lime greens for the ends,” she says. “The hair gets such a nice, bright highlight.”

After chalking, use a blow dryer to set the color and dry the hair.

Use a thermal protectant (Scordato suggests Paul Mitchell’s Hot Off the Press) before using a curling iron to create loose waves.
