There's a myth that permanent hair-color is damaging, but that's only true if you bleach your hair or if you use the color incorrectly.
Meanwhile, semi-permanent colors that are acid-based may protect around the hair cuticle, and acid-based colors may coat -- and protect -- the hair, says Sonia Badreshia-Bansal, MD. She's a dermatologist and clinical instructor at the University of California San Francisco School of Medicine.
Follow these tips to give thinning locks a healthy new hue.
Skip the Bleach
You're most likely to damage your hair if you make a drastic color change requiring bleach, such as going from jet black to blonde. If it's properly applied, regular hair color shouldn't be a problem.
Still, if you’re debating a major color change, you might be better off with a wig.
Check the Contrast
“You never want someone looking away from your eyes and up at your head when they’re talking to you,” says Dave Lemke, owner of Kings Head Hair Salon in Milwaukee, which specializes in clients with hair loss. “If they do, you know something’s wrong.”
As you age, Lemke adds, having lighter hair around your face makes you look younger and softens your features.
Consider Salon Color
“Professionals will have more access to a variety of options and higher-end coloring agents,” Badreshia-Bansal says. Your stylist’s experience with color is important, too, she says.
She suggests you ask about vegetable-based dyes, cellophanes, and hennas, all of which are gentle options for thinning hair. Also, ask your stylist about products that are ammonia- and peroxide-free. And avoid bleach.
Rules for Do-It-Yourselfers
Check the label: Choose brands with less than 20% peroxide, and don't bleach thinning hair.
Think temporary: Use semi-permanent color, if you can. If it doesn’t cover your stubborn greys, apply permanent color at the roots and semi-permanent on the rest.
