Bleach washing is an easy, effective way to remove darker pigments and achieve a lighter base colour level.

If you want to lighten your colour and you already have colour in your hair, your options are limited to colour removal products or bleaching processes.

Colour removal products can lift out some permanent colour pigments, although you may need to repeat this process several times to get the lift you want. Colour removal products won’t lighten your hair beyond its natural colour level.

If you want to either lift out darker colour, colour build-up or lighten your hair beyond its natural colour level then you will need a bleach process. Bleach is the only product which will completely lift and lighten when hair has already been coloured.

Regular bleach applications involve mixing bleach with developer and applying it directly to dry hair, and they will corrode the hair cuticle leaving it prone to breakage. It’s basically the nuclear solution, and should be approached very conservatively.

Bleach washing is a gentler and easier approach to lighten or lift out darker pigments from your hair. A bleach wash uses a bleach mixture blended with shampoo and applied to wet hair. It blends through wet hair quickly and is easier to apply than regular bleach treatments.

All lightening processes will dry your hair, so it is important to boost the hydration and condition of your hair before and after a bleach wash.

We highly recommend thermal Tsubaki oil treatments before and after bleach washes. This thermal oil treatment allows for deep penetration of nutrient-rich oil which will replenish moisture and strengthen your hair.

Bleach washing will:

  • Strip out hair dye
  • Correct over-toned hair
  • Remove excessive brassiness from partially lightened hair
  • Lighten hair colour

Our Bleach Wash Kits include everything you need to bleach wash at home:

  • Hi-Lift Bleach powder 30gm
  • 20 vol developer sachet 75ml
  • Colour Protection Shampoo 20ml
  • Colour Protection Conditioner 40ml
  • Gloves

How to Bleach Wash Your Hair

Avoid washing your hair for at least 2 days before your bleach wash as your natural oils protect your scalp and hair from damage.

Wear a front-opening shirt or robe (not your finest – any stray bleach wash drops will lighten material). Wet your hair and towel dry it before preparing your bleach wash mix.

Use a tint brush and bowl to prepare your bleach wash.

Follow the instructions to mix your bleach wash in the correct ratio. Start by emptying the sachet of developer into your tint bowl. Please note that you will need to remove 15ml of developer (which is one level tablespoon) to get the correct volume to mix with the entire bleach sachet. Use your tint brush to mix the bleach and developer together. 

To this mixture you add 90ml of shampoo to the bleach and developer mix (use any regular shampoo you have at home for this).

Add a little bit of water to your damp hair and then apply the bleach wash to your hair.

The shampoo blend will spread evenly and consistently through your wet hair, giving you a manageable application process, with consistent outcomes.

Leave the mixture in for 10-20 minutes, depending on the colour result you are looking to achieve. Wash it out in the shower, using the Colour Protection Shampoo and Conditioner provided in your Bleach Wash pack.

Leave your hair for at least 2 days if possible before recolouring. You are now free to colour with a lighter colour option, as your base colour level should be at least 1-2 levels lighter.

Bear in mind that when you lighten your colour, unwanted warmth is revealed due to the natural contributing pigment. It is best to recolour with a colour with cool secondary tones which will neutralise and tone unwanted warmth.

We also recommend getting personalised colour advice if you are considering bleach washing your hair.

A Word of Warning:

After a bleach wash your hair will be a bit drier and more porous. We recommend that you do a bleach wash a maximum of 1-2 times a year to lift out darker pigments. They should NOT be used for regular, repeated lightening (at all, please don’t do this!).

Bleach washing can lead to your hair over-absorbing colour when you recolour after bleach washing, which leads to darker colour results. It is generally best to select a lighter colour option with cool tones after a bleach wash. Please speak to our colourists about your colour goals before bleach washing.

Pre and Post-Lightening Care

It is very important to hydrate and nourish your hair before and after a bleach wash. All lightening processes will strip natural oils from your hair, so it is critical to restore oils to rehydrate and strengthen your hair.

Thermal Tsubaki oil treatments are our preferred treatment to strengthen, hydrate and deeply nourish hair before and after a lightening process.

Tsubaki oil is extremely high in oleic acid, proteins and glycerides, which are essential to keeping hair healthy, stronger and shinier. It is a lightweight, dry oil which can be used sparingly. Massage 10-20 drops through damp hair and add gentle heat with a thermal heat cap, which gently softens and lifts the cuticles of the hair, allowing the oil to enter within the hair to work its magic.

Thermal Tsubaki oil treatments will dramatically boost the health, strength, condition and shine of your hair, restoring critical oils and nutrients which are stripped from the hair during the lightening process.

We recommend bi-weekly thermal Tsubaki oil treatments for two weeks before and after your lightening process. Your hair will benefit greatly from the health-restoring properties of tsubaki oil treatments which will reverse damage from the lightening process and restore the condition of your hair.

Very happy with the end result. I used the bleach wash kit first to get rid of excess previous colour. Easy to use & my colour application was even & bright. Have had some compliments & someone not believing I did my colour at home.

I used the bleach wash to get old colour out and then used this colour and am so happy with my new colour! I have received so many compliments.

I have been using The Shade since October 2019. I changed from your normal supermarket dyes to The Shade as my hair was being ruined. After one purchase I was hooked on how full coverage, soft and shiny my hair was. I’ve used The Shade dye and bleaching kit to go lighter on my own with great success and without damage to my hair. For the price it’s definitely worth it and I love you can change the subscription with ease.
