Hair colour idea #1 Silver

silver hair color ideas instagram

Shimmer and shine with Silver.

Silver is a hair colour trend that really took root (sorry!) in 2020 and it’s here to stay as a top hair colour idea in 2021.

It’s a cool tone that mixes platinum blonde and silver hair to create an ashy, shimmery tone. Before diving straight in and choosing a shade of silver you love, you’ll need to take the colour your hair is now into consideration.

Brunettes, you’ll need to pre-lighten your hair first with bleach to achieve the ashy blonde silver colour.

Natural and highlighted blondes are in luck and an at-home silver box dye like this one should give you the silvery silk results.

Best for:

  • Blonde or highlighted hair
  • Paler skin with pink undertones

Not so good for:

  • Brunette hair
  • Warm skin tones

Hair colour idea #2 Chocolate brown.

Sweet like chocolate.

The rich, classic tones of warm brown hair colours are endlessly flattering shades for women of all ages. We particularly love chocolate brown as a dark brown, on-trend hair colour idea as it can make hair appear fuller, thicker and doesn’t appear orangey when it starts to wash out.

Dark brown hair hues are easy to maintain as there are plenty of shampoos, conditioners and root touch-ups that cater for various shades of darkness and depth.

Natural brunettes will find their colour is enhanced with chocolate brown and we find even our skin appears more vibrant and healthier too! It’s also an amazing base for balayage, blonde and caramel highlights and ombre hair styles that are all over our insta feed this year.

For blonde hair, this is not as simple as colouring your blonde locks brown. You can dye your hair a neutral or warm brown after filling your hair with a copper or red shade, but this is an intensive process that’s best left to the professionals to get it right. 

Best for:

  • Brunettes of all shades
  • Making hair appear fuller, thicker and healthier.
  • Warmer skin tones

Not so good for:

  • Blondes
  • Cool undertones.

Hair colour idea #3 Lilac.

Get the pastel perfection.

Lilac hair colour is the latest pastel hair colour idea to make its debut. Pastels are a major hair colour trend for 2021 and lilac is one of our faves. Derived from the pink pastel pallet, lilac is a hue that comes in many variations – from dusty lilac to lilac pink. Every one gives you a creatively gorgeous hair colour that’s bang on trend.

You can nail the lilac trend with a home dye kit although your locks will already need to be bleached, highlighted or naturally light blonde for the full effect.

For a dusty lilac look, try the L’Oréal Paris Colorista Semi-Permanent Hair Color in Purple, which is formulated to work on blonde, highlighted, and bleached hair. It’s semi-permanent and you can dial down the vibrancy if you need to by mixing it with conditioner.

Best for:

  • Blonde, bleached or highlighted hair
  • Light brown is a maybe – do a test
  • Fairer skin tones

Not so good for:

  • Darker brunettes
  • Warm skin tones

Hair colour idea #4 Midnight blue.

The cool cover of darkness.

Bright, rainbow pastel hair colours aren’t the only way to make a colourful statement with your hair this year. We can’t get enough of edgier shades like midnight blue. 

One of the best things about this blue black hair colour, is that since it’s such a dark shade, you won’t have to have your hair bleached to get the look. So it makes it a colour trend that’s totally doable at home.

We particularly love how this looks on black hair and we love the variations with low-lights and dipped ends although you’ll need a hairdresser’s help to nail these awesome looks.

For a semi-permanent midnight blue option, Garnier Nutrisse Permanent Hair Dye in Midnight Blue is the one for you. It’s designed for darker hair but keep in mind that it will start to wash out over the course of about four to ten shampoos.

Best for:

  • Mid brown or dark blonde hair for the most vibrant results
  • Dark Brown and Black for a more subtle wash
  • Particularly powerful with short hair styles
  • All skin tones

Not so good for:

  • Bleach blondes will get a brighter blue and not the midnight blue effect

Fire up!

Velvety, fierce, sexy and luxurious, red hair is more than a hair colour idea, it’s a statement. Red hair says you’re up for some fun and you don’t care who knows it. This is in the top hair colours 2021 but the red hair trend is here forever. 

The best thing is, red hair works for everyone. Every skin tone, every eye colour, It’s all about finding the hue that works for you,

The lighter your hair, the pinker your red will be compared to a brunette who will experience darker and richer shades of red. Experiment with shades lighter or brighter than you normally would. That’s what having new hair colour ideas are all about.

Best for:

  • Everyone!

Not so good for:

  • No one!
