8 Ash Brown Hair Colour Ideas for a Cosy, Cool-Toned Brunette

You've heard of ash blonde, but what about ash brown hair colour? This cool-toned shade is rich, sultry, and effortlessly chic, giving brunettes a smoky finish that feels both modern and timeless. From mink-toned highlights to an earthy balayage, there are so many ways to wear this trend. Ready to find your perfect shade? Let’s take a look at the coolest ash brown inspiration to take to your nearest Wella salon.

What is Ash Brown Hair Colour?

Ash brown hair colour is a modern, cool-toned brunette shade that blends deep brown with smoky, muted hues. Instead of the golden or reddish warmth found in traditional brown shades, this colour leans toward an icy, silvery finish, giving it a sleek and sophisticated look.

It's an ultra-versatile shade, too, letting you unlock the trend with highlights, balayage or an ombre finish. So, no matter what hair colouring techniques you crave, there's an ash brown look for you – as you'll see in our round-up below.

What Skin Tone Looks Best with Ash Brown Hair?

Ash brown hair colour is a flattering choice for a wide range of skin tones. It just depends on whether you prefer your shade to work in harmony with your complexion or you want to create a striking contrast. On a cool skin tone, ash brown hues help create balance by softening redness to make skin glow. Meanwhile, on warmer skin tones, a neutral brown base with ash brown balayage lets you go smoky without overwhelming your natural warmth.

How to Maintain Ash Brown Hair Colour

1. Wash with a Shine-Boosting Shampoo and Conditioner

Ashy tones can appear dull without the right hair care routine in place, so make sure you use shampoos and conditioners that focus on shine. ULTIMATE SMOOTH Shampoo and ULTIMATE SMOOTH Conditioner are your deeply nourishing glow-boosters, with a dose of Squalane and Omega-9 working to nourish hair from the inside out. Together, they leave your hair clean, light and cared-for from root to tip, with frizz-free smoothness and a glass hair shine that makes ash brown tones sparkle.

2. Enhance the Effects with a Nourishing Hair Oil

Add extra shine with a luxurious hair oil that multi-tasks in your regimen. ULTIMATE SMOOTH Miracle Oil Serum is a sumptuous serum, nourishing oil, heat protectant and UV shield in one. Apply it through the mid-lengths and ends of damp or dry hair to dial up the glassy, glossy finish. It nourishes in 30 seconds for smoothness that lasts up to 3 days⁶ – perfect for longer-lasting, ultra-silky blow-dries.

3. Keep Hair Cool with a Colour-Depositing Mask

If your hair is prone to brassy yellow tones, make sure you keep a colour-depositing mask in your kit. The right one, in the right shade will help to neutralise brassiness in between salon visits. We love Color Fresh Mask, as it gets to work in just 10 minutes, reviving and refreshing your tone. Choose the shade Pearl Blonde if you have ash blonde highlights in your hair, or Cool Espresso if your ash brown mane is deep and smoky. Simply smooth your shade of choice through clean, damp hair, let it develop for the full 10 minutes, and then rinse thoroughly. The lustrous results can be seen instantly.
