Hair color isn’t the only thing that produces brassiness over time. Smoke, swimming pools with chlorine, sun exposure, pollution, heated styling tools, hairsprays, and other styling products can all cause stubborn, yellowish deposits on the hair.
A good purple toning shampoo will correct the unwanted undertones and neutralize your strands without stripping them of much-needed moisture.
There are a wide variety of purple toning shampoos out there to consider, so you have a lot of choices. You can also try a quick purple hair mask for some deep conditioning and for keeping those bright, cool tones looking fresh and clean.
Hair color specialists also have a natural treatment you can try to maintain that bright, fresh blonde shade at home. A once-weekly white vinegar rinse after shampooing is excellent for both permanently color-treated and virgin hair.
Vinegar helps balance out the pH levels and is effective at closing the cuticles and making hair smoother with less tangling.
