FAQs
What Is Mushroom Brown Hair?
Quite literally, mushroom brown hair is inspired by the underside of a portobello mushroom. It’s a muted, earthy brunette, with a mix of neutral to cool undertones and layers of ashy taupes and creamy grays. It's easy to adapt according to the hair's base colour, through a blend of highlights and lowlights that reflect light beautifully. The result is a custom, multi-tonal shade that’s flattering on virtually every skin tone. Extremely versatile and easy to maintain, here’s more on the mushroom brown hair colour trend.
Is Mushroom Brown Cool or Warm?
Because of the gray, smoke, beige and ash undertones, this multi-dimensional, earthy shade of brown tends to lean neutral to cool. But it can be easily adjusted for warmth by pulling shades of gold, honey, and copper into the base for more of a mushroom bronde. Or by pairing a cool mushroom base with these same warm shades in the form of highlights.
Mushroom Brown vs. Ash Brown
Mushroom brown and ash brown are similar, but not exactly the same. Mushroom brown is a cool-leaning, multi-tonal blend with gray-beige dimension, and ash brown is a singular cool shade. So while mushroom brown features several different tones, including ash, ash is a uniform shade of brown.
Who Does Mushroom Brown Hair Look Good On?
Mushroom brown hair is incredibly versatile and looks good on just about everybody. Because it’s made through a blend of highlights and lowlights, it’s easy to adapt according to the hair's base colour, skin tone and eye colour. The result is a custom, multi-tonal brown that helps to neutralize unwanted red brassy tones in the hair and can make the face appear less red. So it’s flattering on virtually everyone. But this cool hue works especially well on people with warm skin, when adding too much warmth to the strands can look unnatural and washed-out. A mushroom brown hair colour is also a favourite for blending grays, helping to seamlessly transition ashy hair into cooler dimensions.
Mushroom Brown Hair Colour Ideas to Bring to the Salon
This expensive brunette shade is rich and multi-dimensional, with lots of room for customization. Need some inspiration before you head to the salon? From dark and moody, to bright balayage and subtle babylights, these are our favourite ways to wear the mushroom brown hair colour trend.
Dark Mushroom Brown Hair
The darker you go with this pretty shade, the chicer it looks. We love dark mushroom brown hair on cooler skin tones and natural level 3-4 brunettes. This version mixes a deep, dark espresso base with ribbons of smoky gray, taupe, or ash, and grows out beautifully without turning overly brassy.
Mushroom Brown Balayage
Mushroom brown balayage is the lowest-maintenance version of this hair colour trend, featuring dark brown roots that seamlessly melt into cool taupe, hand-painted ends. The best version for transitioning to gray, smoky blonde highlights look effortless with a lived-in brown base. And this one’s flattering against both cool and warm skin tones.
Mushroom Brown With Babylights
Cool babylights against a darker base create soft, seamless dimension for the subtlest take on mushroom brown hair. Fine, high-contrast ribbons add a smoky finish that reduces unwanted warm, orange, or red tones in lighter brunettes. Try it with face-framing layers or a set of curtain bangs.
How to Ask Your Stylist for Mushroom Brown
If you’re ready to get on board with mushroom brown, book an appointment with a professional colourist who specializes in brunettes. Ask for a cool-toned ash brown base, with soft highlights and lowlights for a multi-tonal effect, and a beige, taupe, or gray-based toner. Be sure to bring two to three reference pics. Based on your photos, skin tone, and base colour, they will determine which undertones make up your most flattering mushroom brown hair colour. But keep in mind that if your hair is very dark, or previously coloured, it may take more than one appointment for a colourist to get your hair the colour you want. This service involves chemical lighteners, and while it’s a colourist’s job to colour your hair, maintaining the integrity of your strands is always their first priority.

How to Keep Mushroom Brown Hair Cool and Glossy
Mushroom brown is a fairly low maintenance hair colour. Your biggest concern with this hue is brass prevention. Opt for a colour-safe, sulfate-free shampoo and conditioner and turn down the water temperature when you wash. Hot water strips moisture from your strands, leading to colour loss, and weak, dry hair. Finish with cool water to seal the cuticles after washing. Swap in a purple shampoo for brown hair once or twice a week to keep your shade from drifting warm, and follow with a pigmented conditioner. Leave it on for a few minutes to deposit colour, then rinse thoroughly.
A weekly deep-conditioning hair mask is another must with colour-treated hair, along with using a heat protectant, since hot tools and dryness can fade tone and weaken the hair structure. Incorporate smoothing products for frizzy hair, like a lightweight smoothing leave-in, so your ashy dimension stays glossy instead of flat. Frizz reads as dullness on cool shades, especially with dimensional ones, like mushroom brown, that rely on tone and shine. These hues look best on smooth, light-reflecting hair. And finally, depending on how fast your hair fades, an in-salon hair toner service every six to eight weeks will keep your mushroom brown looking fresh.
SMOOTH + SHINE
Cool tones look their best on smooth, light-reflecting hair, so using a leave-in that delivers up to 72 hours of frizz control without weight will ensure your hair looks fresh everyday. Plus, this smoothing milk leaves hair up to 2.5x shinier after one use and provides heat protection up to 446°F.

Is mushroom brown hair high maintenance?
Mushroom brown is a fairly low-maintenance hair colour. These tips will help you prevent brass, keeping your shade cool and vibrant:
- Use a sulfate-free shampoo for coloured hair and conditioner for coloured hair
- Turn down the water temperature when you wash; hot water strips moisture leading to colour loss, and weak, dry hair

Can you get mushroom brown hair without bleach?
Depending on your starting base colour, you may be able to achieve a mushroom brown without bleach. If your base is dark blonde to medium brown, a gray, beige, or cool taupe undertone dye or colour-depositing mask can likely get you there. But you can’t reach a true mushroom brown without bleach if your hair is dark brown or jet black, because dye can’t lift dark colour to an ash tone without chemical lighteners.
