Hair 101: How To Change From Blonde To Brunette

Ready to go Darker? Here's how to avoid the pitfalls and ensure your Blonde-to-Brunette transition is smooth and stunning.

Coco Chanel once said, “A woman who cuts her Hair is about to change her life”. True Coco, but have you ever Coloured your Hair such a different Shade that when you walk past the mirror you don’t realise you’re looking at yourself? Thrilling.

So when that Colour change starts calling, it's worth reading about the nitty-gritty details now you're ready to pull the trigger. Whether you're ready to embrace a big Colour change or transitioning to a more Natural, low-maintenance Colour, you'll find everything you need in this Hair 101: How To Change From Blonde To Brunette guide.

Before You Start

How many Shades are you travelling down the Colour ladder? If you're making a big jump from Blonde to Brunette, there's a chance your Hair could end up Lighter, washed out with a green tinge. Essentially, if you’re Colouring your Blonde Hair with a Brunette Shade that's 3 or more Shades Darker, you'll need a Colour Filler.



What Is A Colour Filler?

When you’re Colouring your Hair 3 or more Shades Darker, a Colour Filler bridges the gap between your current and new shades by restoring pigment that may have been lost during lightening.

A Colour Filler is an intermediate Hair Colour applied before your Brunette Shade. It helps rebuild the pigment in your Hair and prevents the Lighter, washed out greenish or khaki tones. This step is essential for achieving a true, rich Brunette colour.

If your transition isn’t as drastic, you can skip this step and apply your new Shade directly. And one more thing—if your Hair is Naturally light, without any previous lightening treatments, a Colour Filler isn’t necessary for you either.

How To Know If You Need A Colour Filler

To determine if you need a Colour Filler, use our simple formula:
Your pre Lightened Colour number (find the Colour closest on the Natural Hair Colour Chart)
(minus)
Your goal Colour number
=
The number of Shades you need to Darken your Hair.

If the result is 3 or more Shades Darker, you’ll need a Colour Filler to achieve the best results and avoid any unwanted Tones.



How To Choose Your Colour Filler

Because the Lightening process strips Warmth from your Hair, Warmth is exactly what we need to put back in with your Colour Filler. Choose a Golden or Chocolate Hair Colour that is 1-2 Shades Lighter than your goal Brunette and mix with a No Lift Developer. A Colour Filler needs to have a Warm pigment, regardless of the Brunette you want to be.
