Why Blonde Hair Gets Brassy in Summer (And How to Prevent It)

One of our summer favorites for blondes and color-treated hair. Davines SU helps protect against sun exposure while keeping hair hydrated.

If you’ve noticed your blonde hair getting brassy faster in summer, you’re not imagining it.

Sun exposure, chlorine, saltwater, hard water, and product buildup can all shift blonde hair warmer faster than usual—especially in NYC summers.

The Sun

UV exposure can fade toner faster and shift blonde warmer over time.

If you spend a lot of time outside, protection matters.

We love the Davines SU line this time of year for helping protect hair from sun exposure while keeping it hydrated.

Pool + Beach Days

Chlorine and saltwater can dry blonde hair out fast and sometimes leave it looking dull or discolored.

Even just rinsing your hair before and after swimming helps.

Product Buildup + Hard Water

Dry shampoo, styling products, oils, and NYC water can all make blonde start looking muddy faster than you’d think.

Sometimes it’s not your toner—it’s buildup.

A favorite Gem House remedy is to clarify your hair once a week using Davines Solu shampoo followed by a Davines Chronicle Circle mask.

Heat Styling

Hot tools + blonde hair can be a rough combo without protection.

Heat can contribute to dryness, fading, and extra warmth showing through.

A Gloss Usually Fixes It

Sometimes the easiest solution is just a quick refresh.

A clarifying shampoo and then a gloss can help tone down warmth, bring back shine, and make your blonde feel expensive again without a full blonding appointment.
