8 Ways to Correct and Avoid Brassy Hair

Of all the dreaded hair woes, brassiness ranks high on the list. Brassy hair rears its ugly head especially when tresses are not properly treated after colouring. The result is an over-abundance of warmth in the hair — think platinum blonde that becomes too yellow or golden highlights that turn orange. When hair is lightened, your natural hair colour is lifted to make room for the new colour. Because all hair has some measure of underlying warmth, the removal of your natural hue makes yellow, orange or red tones more evident, unless steps are taken to mitigate it. However the warmth presents, no doubt you’ll want get rid of your brass and get back to the cooler tones you originally sought. Better yet, use preventative measures as your brassy blonde hair fix.

1. Be Strategic With Colour Use

Instead of going with a single-process all-over blonde colour, have your colourist work in highlights and lowlights versus colouring every strand. This minimizes the potential for a whole head of brassiness. Remember, the closer your hair's final colour is to its natural colour, the less room there is for the colour to turn; it’s recommended that you don’t lighten your hair beyond two shades from your natural colour. Be calculated with your colour choice to begin with, and you up your chances for eliminating a brassy future.

2. Avoid Direct Sunlight

The sun has a tendency to not only dry hair but fade its colour, too. On top of that, being outside speeds along the Oxidation of your freshly coloured tresses. When hair is exposed to both oxygen and UV rays, the underlying warmth in your hair is revealed and — before you know it — brassiness abounds. If you can’t stay out of the sun, try wearing a hat to protect your locks or a UV-protectant spray to avoid unwelcome brassiness.

3. Keep Cool

It may be a tough pill to swallow, but rinsing your hair with cool water is better for preserving your colour. Instead of pumping up the heat, use a cool rinse to close the cuticle cells. This has the added benefit of locking in moisture and helps the cuticle to lay more smoothly and appear glossier and shinier.

4. Avoid Pool Pitfalls

Chlorine is not your hair’s friend. This chemical is notorious for stripping hair of its natural oils and leaving it dry and brittle. The more damaged the hair becomes, the more susceptible it is to turning brassy. To counteract this problem, try dousing your hair with bottled water before jumping in the pool. Your hair will soak up any sort of moisture, so give it clean, non-chemically altered water first before you swim. When you’re finished in the pool, shampoo and condition your hair immediately to undo the potential damage. Better yet, try to stick to salt water pools if it's an option.

7. Wash Less and With Filtered Water

High mineral levels in water can cause hair to turn brassy. Hard water deposits colour-tainting minerals onto your tresses  while simultaneously locking out moisture. Consider cutting back on the amount of time you wash your hair weekly, and if your water is particularly hard, you may wish to invest in a water filter that sifts out the minerals. Worried your hair will look dirty? A bun or braid paired with some dry shampoo should do the trick.

8. Keep Hair Conditioned

It may seem simple, but the more healthy, soft and supple your locks are, the less likely your colour will fade or turn. This can be accomplished by using a deep-conditioning treatment. After treating your hair, seal your style with a hydrating, shine-infusing gloss. Just be sure that the gloss is either clear or properly pigmented to cancel out brassiness.
