Plus, how to prevent brass and maintain that fresh-from-salon look with K18 tech.
The short answer: Everything from UV rays to chlorine to a dip in the ocean leads to oxidation in blonde hair which often means summer brings brass.
It’s about to be summer which means a lot of fun in the sun: pool parties, picnics, maybe even a tropical vacation. But what do all these beach days do to your blonde? We’re here to break it all down with science, so you can know exactly what’s happening to your hair during the warm months and how to address it head-on (pun intended).
summer vs. blonde hair
Blonde hair is especially vulnerable to environmental aggressors—and summertime brings its fair share. Case in point: Increased exposure to the sun’s UV rays, chlorine from the pool, and salty sea water all play a role in shifting your shade.
At the center of it all is oxidation: a chemical reaction that occurs when hair is exposed to oxygen and environmental stressors like the ones just mentioned. For the unfamiliar, oxidation is directly responsible for blonde hair going brassy—and during the summer, this process speeds up. UV rays from the sun break down color molecules, while chlorinated pool water and salt water strip the hair and leave it more porous (and in turn, more prone to fading).
This—on top of daily buildup from minerals and metals found in unfiltered tap water—results in blonde hair turning brassy fast. Like really fast. The good news? It can be corrected and prevented with the right products. TripleBright oxidation defense purple shampoo was formulated to defend all highlighted + lightened tones from oxidative damage. So rest assured, the future of your blonde is looking bright.

how to prevent fading + keep your blonde bright
A few smart habits can make all the difference in protecting your blonde from summer stress.
Start with physical protection—wearing a wide-brimmed hat or chic driving scarf when you’re out in direct sun helps shield your strands from UV rays, thereby slowing down the oxidation process. It’s one of the simplest ways to preserve brightness.
Next up, consider incorporating UV-protective hair products into your routine. Just like SPF for your skin, these formulas help defend against sun damage and keep your strands looking healthier for longer. This might sound highly specialized, but it can actually be as simple as…taking a shower. damage shield protective conditioner is clinically proven to provide conditioning protection against damage from UV rays, mechanical styling, and environmental aggressors for up to 3 days*
