Brown hair with forest green undertones keeps necks 5 degrees cooler (summer’s subtle sophistication)

Summer is here, and what better way to refresh your look than with the subtly sophisticated trend of forest green undertones in brown hair? This June 2025, as temperatures rise, this cool-toned technique offers a refreshing twist to traditional brunette shades without the commitment of a complete color overhaul.

Why forest green undertones are summer 2025’s coolest trend

Forest green undertones create a multidimensional effect that catches light differently as you move, adding depth and interest to brown hair without overwhelming your natural color. Color specialist Mia Chen from Emerald Studios explains, “Unlike bold fashion colors, forest green undertones work with your natural brown base to create a sophisticated, almost jewel-like dimension that’s perfect for summer sophistication.”

The coolness of these green tones can actually make you feel more comfortable during hot summer days. Many clients who’ve tried cooler June haircuts report that adding these undertones creates a psychological cooling effect that complements seasonal styles.

How forest green undertones work with different brown shades

This technique is remarkably versatile across the brunette spectrum:

  • Dark brown hair: Creates subtle emerald reflections visible mainly in direct sunlight
  • Medium brown: Offers the most noticeable dimension with forest green highlights
  • Light brown: Creates a striking contrast that can be adjusted for boldness
  • Ashy brown: Enhances the cool tones for a sophisticated, modern look

The perfect summer styling techniques for green undertones

Those who style medium-length shags for June heat will find that forest green undertones look particularly striking with textured cuts. The movement highlights the dimensional color effect, creating a natural-looking play of light and shadow.

Celebrity stylist Jason Rodriguez notes, “Forest green undertones are like having a secret garden hidden in your hair—subtle enough for professional settings but with just enough edge to stand out from the crowd.”

Application techniques for the perfect forest green undertones

Professional colorists typically use several approaches to achieve this look:

  • Balayage: Hand-painted sections for the most natural-looking result
  • Lowlights: Strategic placement underneath top layers for a peek-a-boo effect
  • Micro-highlights: Thin strands of forest green woven throughout
  • Ombré: Gradual fade from brown to subtle green tips

Maintenance tips for lasting summer color

To keep your forest green undertones vibrant through summer activities, use color-safe shampoos specifically formulated for cool tones. Those who’ve tried layered hairstyles for summer heat will find that these cuts require less maintenance while showcasing the green undertones beautifully.

For those over 50, specific summer cuts that tame thick hair pair wonderfully with these undertones, adding youthful dimension without appearing too trendy.

Perfect for beating the summer heat

Much like how specific summer hair trends make your neck feel cooler, forest green undertones create a visual cooling effect. The deep, cool-toned green gives the impression of shade and freshness, making it a psychological summer refresher.

Consider forest green undertones as your hair’s personal air conditioning—they won’t literally cool you down, but they’ll give you that refreshing forest ambiance even on the hottest June days.

Who should try forest green undertones this summer?

This technique works particularly well for those with:

Olive or neutral skin tones that complement the coolness of forest green, though virtually any skin tone can find a suitable depth and intensity. If you’ve been hesitant about fashion colors but want something beyond traditional highlights, forest green undertones offer that perfect middle ground—sophisticated with just enough edge for summer 2025.
