Trips to the Pool Have Turned Your Blonde Hair Green
Similar to the oxidation process that turns copper metal to a turquoise color, chlorine conflicts with the hard metals in the pool water and creates a similar reaction. As a result, these metals absorb into your hair while you're splashing about. Help keep your hair its normal hue with a postswim shampoo using a formula specially designed to remove pool and hard-water buildup.

To prevent your hair from going green (and not in an eco-friendly way) in the first place, "rinse your dry hair with bottled or filtered water to saturate the hair shaft," advises colorist and NYC salon owner Joel Warren. "That way, your mane won't soak up whatever is in the water."
Your Highlights Are Getting Sassy and Brassy
The sun is a catalyst that brings out unwanted warmth in your newly highlighted or lightened strands. Look for shampoos that contain blue or violet pigment to counteract yellow, red, and orange tones. "Try Clairol Shimmer Lights Shampoo and use it once a week to keep your color bright in between salon appointments," says celebrity colorist and NYC salon owner Marie Robinson.
Another option is L'Oréal Colorist Secrets Brass Banisher — a five-minute gloss treatment that eliminates brassy tones and delivers balanced color with shiny, healthy results.
