September is that enchanted middle-ground, when the sunshine of summer is still in the air, but the warmth of autumn is beginning to show itself. It is the right moment to update your style with the colors that seem to be seasonal but universal. Whether it is glowing blonde or deep brunette and fun fashion shades, the Hair Color Trends of September 2025 are all about depth, texture and personality.
No matter which direction you are going, whether it is subtle highlights or a statement shade, the palette of this season has something to offer to every mood.
Textured Brunette with Soft Layers
Our September 2025 Hair Color Trends lineup starts with a look that is all about depth and movement. This is a layered brunette with soft waves that is the ideal combination of casual and elegant. The cut is easy to frame the face, and the slight texturizing does not make it too heavy. The rich chocolate base is not flat-looking, and it is an ideal combination with early fall light. It is the sort of shade that makes ideas brunette feel new once more–plain, but with a twist.
Keeping brunette tones glossy requires a little TLC. I adore switching between a color-safe shampoo and a hydrating mask once a week- Redken Color Extend Magnetics is my favorite to use to lock in pigment and avoid dryness. And when the cooler air begins to creep in, a drop of light hair oil on the ends is all the difference.
There’s something timeless about this style. It is a year-round winner as it does not scream elegance. A rich brunette, as celebrity colorist Tracey Cunningham likes to say, is like a great pair of jeans, it goes with everything and only gets better with wear.
Fiery Copper Blonde Blend
This is a bold hearted one-an ideas blonde and copper mix that almost glows. The upper strands are colored in a bright cinnamon-red that blends into creamy blonde tips. It is dimensional, eye-catching, and so much of a statement in early autumn. That is precisely the sort of high-contrast mix that causes heads to turn and Pinterest boards to fill.
For a multi-tonal color like this, moisture is everything. Between salon visits, both the warm and light tones can be maintained with a weekly gloss treatment, such as the dpHUE Gloss+ in Copper. I have come to understand that when you are wearing a showstopper shade, maintenance is part of the magic.
I would honestly wear this to a fall wedding. The contrast is so pretty in natural light and the warmth is so welcoming. It’s the ultimate “hello September” color moment.
Honey-Toned Long Layers
Here’s where ideas brunette long meet understated elegance. Long, sleek locks cascade in a cascade of honey and sand-colored brunette, providing the perfect amount of brightness without leaving the brunette family. The advantage of this style is that it is versatile- it can be worn with jeans and boots as well as a tailored coat.
I am religious about a heat protectant when hair is this long. My favorite is the Oribe Invisible Defense Universal Protection Spray, which protects without weighing hair down or leaving it greasy.
The best thing about this color is that it matures well. The warm undertones make it look purposeful even as the gloss fades. It is its low-drama beauty, which occasionally is just what we need in the frenzy of fall.
Soft Blonde Shag with Fringe
The shags are here to stay in 2025, and this sandy blonde one shows why. The fringe is light and airy, and the layers are tousled, which adds an immediate je ne sais quoi to the entire look. It is young without being too sweet, which is what I would recommend in case you are seeking ideas that are short and yet have movement.
This chop looks good with a little natural texture, so I would have a sea-salt spray at the ready. I prefer Bumble and bumble Surf Spray to that just-right, undone wave. And since fringe can be a commitment, it will be kept fresh by regular trims every four to six weeks.
It is the type of hair that you can shake out on a crisp September morning, run a little product through and be on your way to a coffee date. Low effort, high payoff.
Chestnut Mid-Length with Face-Framing Layers
Warm, rich and flattering to no end, this chestnut mid-length cut is the type of style that immediately revamps your appearance. The delicate caramel streaks around the face are ideal to thoughts brunette highlights, and they provide radiance without the high-maintenance care.
To keep those highlights luminous, I recommend a purple shampoo every other week, like Amika Bust Your Brass Cool Blonde Shampoo—yes, brunettes can benefit from it too! It keeps caramel tones from veering brassy.
This is the type of haircut I would recommend to anyone who is transitioning to color change. It is a kind of a have your cake and eat it too kind of thing, soft enough to wear to the office, but still interesting enough to have plans after work.
Velvety Burgundy Waves
The deep burgundy tone here is pure autumn romance. It’s bold without screaming, rich without feeling heavy. It is luxe, almost velvet-like, and when combined with soft waves, it becomes one of my favorite concepts to wear in cooler weather.
To keep a shade such as this, it is important to avoid harsh shampoos and to use color-depositing conditioners, such as the Overtone Extreme Purple, to keep the tone lush.
I have had a shade like this before and whenever the light hit it just right it was like my own little secret weapon. A deep red in September is something powerful–the hair version of a perfect berry lipstick.
Layered Brunette with Sunlit Highlights
Our final in this series is a combination of the depth of brunette with golden ribbons that resemble late-summer sunshine. The layering creates a sense of movement and dimension and is an ideal transition shade in September. This is the ideas brunette highlights look I would encourage you to go to if you are on the fence about going lighter.
