When you first leave the salon, your color looks perfect and beautiful.

Most of us know that the way to combat warmth in hair is to counteract it with a cool tone. This most often takes the form of a gloss or toner that is applied after the hair has been lightened. But what happens when you leave the salon and that toner gradually fades out? To help maintain the tone and brilliance of your hair color at home, try a blue or purple shampoo.

The following shampoos are great for helping maintain blonde hair color:

  • Blondeshell Debrass Shampoo by Keratin Complex
  • Bleach Blondes Shampoo by Lee Stafford
  • Sterling Silver Toning Shampoo by AG

Kool It Down

Need to tone down the brass in your hair and don't have any blue or purple shampoo on hand? Solve the problem by mixing a packet of blue Kool-Aid and with a small amount into a handful of conditioner until it turns blue. Apply it to damp hair, let it sit for a few minutes, and voila. Brassiness is toned down.

Note of caution: If you have platinum blonde or extremely porous hair, the Kool-Aid trick probably isn't the best option. The porosity in the hair could cause it to grab onto the blue too much, and then you'll have a much bigger problem on your hands.

The sun can be a major culprit when it comes to brassy hair. To prevent this, wear a hat at the beach or use a hair product that has sunscreens. 

Some hair products with sunscreen include:

  • Soleil by Kerastase (this product also protects from the effects of chlorine)
  • Olio di Jasmine Shine Spray by Oscar Blandi
  • Phytoplage Protective Beach Spray by Phytologie

Chlorine and saltwater also like to wreak havoc on colored hair. It's important you take the necessary steps to protect yourself from these elements. Slathering damp hair in conditioner before putting on a swim cap is the best protection against the lovely green hue that chlorine likes to leave behind

A very simple way to protect your hair color is to install a water filter in your shower head. This is an inexpensive option that will cut down on the chlorine and iron deposits in the water which will eventually turn your hair brassy. Diminishing these elements in the water that comes in contact with our bodies every day is probably a healthy option regardless if you color your hair or not.
