I don't know about you, but I've already seen my fair share of hair transformations this year. It seems that lots of people are embracing the "new year, new me" mindset and switching up their look for January and beyond. If you're wanting to change your hair colour, you may have already come across my guide to the biggest hair colour trends of 2025, which is filled with expert recommendations. One of the key trends for this year is cool brunette shades, but it seems as if there's a particular hue that people can't get enough of. Say hello to "mushroom brown".
I had a look on Google Trends at the start of the year to see what hair colours people were searching for and this was one of the most popular results. You may be thinking, what is mushroom brown hair? Well, as the name suggests, this cool brunette shade features ashy, grey undertones which are reminiscent of a mushroom. It's pretty much the opposite of those warm brown shades we've been seeing for the past year or two, and is a super cool, sophisticated colour to try out in 2025.
Not convinced? I've rounded up some of my favourite mushroom brown hair inspo pics below, and I'd be lying if I said that these looks weren't convincing me to give the trend a go. From mushroom brown highlights to all-over colour, keep on scrolling for some of the coolest looks around...
