10 Shocking Ways To Style Brown Hair With Blonde Underneath: The Ultimate 2025 Peekaboo Trend Guide

The "brown hair with blonde underneath" trend, often dubbed the 'Peekaboo' look, is more than just a fleeting hairstyle—it's a high-impact, low-commitment color strategy that continues to dominate salons in late 2025. This style offers the perfect blend of professional subtlety and edgy drama, allowing you to flash a hidden layer of bright blonde whenever you move, flip your hair, or tie it up. It’s the ultimate versatile look for anyone wanting a bold change without committing to all-over lightening, making it a powerful choice for the current year.

This dynamic two-tone effect is a strategic color placement that keeps your natural brown shade on the top layer, providing a beautiful contrast to the vibrant blonde hidden beneath. The beauty of this technique lies in its customizability, allowing for shades from subtle honey blonde streaks to dramatic platinum chunks, ensuring your look is uniquely yours and incredibly current.

The Anatomy of the Blonde Underlayer: Peekaboo vs. Money Piece

While the concept of adding blonde to brown hair is not new, the "blonde underneath" trend has evolved into several specific techniques, primarily centering on the Peekaboo highlight. Understanding these terms is crucial when discussing your desired look with your colorist to achieve the perfect result.

What is Peekaboo Hair Color?

The Peekaboo technique is the direct answer to "brown hair with blonde underneath." It involves isolating the lower section of your hair, from the nape of the neck up to the occipital bone (the prominent bone at the back of your skull), and lightening only that layer.

• Placement: The color is applied to the very bottom layer of hair, completely hidden when the hair is worn down and straight.
• Reveal: The blonde is revealed when the hair is styled in an updo, a half-up style, or when a sudden gust of wind catches the strands. This creates a shocking, high-contrast effect.
• Maintenance: Generally lower maintenance than traditional highlights or balayage since the blonde roots are concealed by the dark top layer as they grow out.

The Money Piece and Underlayer Combo

For those seeking maximum impact, many stylists are now combining the Peekaboo underlayer with a "Money Piece." The Money Piece refers to strategically placed, bright highlights that frame the face.

• Effect: This combination gives you a bright blonde pop around your face (the money piece) and a hidden, full blonde layer underneath (the peekaboo).
• Contrast: It amplifies the contrast, allowing you to have a dark, rich brown base with two distinct, high-impact blonde sections.

This method offers the best of both worlds: a bright, face-framing glow and a shock of color hidden beneath the surface, making it one of the hottest color trends of 2025.

Choosing Your Perfect Blonde Shade: Tonal Harmony is Key

The success of the blonde underneath trend hinges on selecting a blonde shade that complements your natural or dyed brown top layer. The latest trends emphasize tonal harmony or a deliberate, striking contrast.

For Cool-Toned Brunettes (Ash Brown, Espresso):

If your natural brown has cool, ashy undertones, you should opt for a cool-toned blonde for the underlayer.

• Ash Blonde: A subtle, muted blonde that works beautifully with ash brown hair, preventing brassiness.
• Ice Blonde / Platinum Chunks: For a bold, edgy look, platinum blonde offers the highest contrast against dark espresso or black-brown hair. This is a high-impact, statement-making choice.

For Warm-Toned Brunettes (Chocolate, Caramel, Toffee):

If your brown hair has warm, golden, or reddish undertones, a warm blonde will ensure a natural-looking blend when the layers mix.

• Honey Blonde Streaks: A rich, golden blonde that melts seamlessly with chocolate brown hair, creating a soft, sun-kissed peekaboo effect.
• Caramel Bronde: A blend of blonde and brunette, this shade is perfect for a subtle underlayer, especially on light brown hair, offering a softer transition.
• Walnut Blonde: A creamy, rich blonde that balances golden and warm tones, ideal for medium skin tones.

10 Stunning Ways to Style Your Brown Hair with Blonde Underneath

The entire purpose of the blonde underlayer is to be seen—or hidden—at will. Certain hairstyles are specifically designed to maximize the reveal of your Peekaboo color.

1. The Half-Up, Half-Down Reveal: This is the classic way to show off your underlayer. By pulling the top, brown section into a bun or ponytail, the entire blonde layer is exposed, creating a dramatic, two-toned look.
2. Loose Waves and Curls: Styling your hair in loose waves (using a curling iron or flat iron) allows the brown and blonde sections to intertwine and layer, adding incredible dimension and movement.
3. High Ponytail Flip: A high ponytail causes the underlayer to flip out and cascade down the back of your head, making the blonde the dominant color from the back view.
4. The Shaggy Bob with Texture: For shorter hair, a choppy blonde balayage bob or a shaggy cut with layers will naturally separate the top and bottom colors, ensuring the blonde peeks through with every movement.
5. Deep Side Part: A deep side part causes the top layer of brown to fall over, revealing a sliver of the blonde underneath on the opposite side, especially if you have an accompanying Money Piece.
6. Braided Accents: Incorporate the blonde sections into a crown braid, Dutch braid, or French braid. The contrast in color will highlight the texture of the braid, making the style pop.
7. Curtain Bangs Integration: If you have curtain bangs, lighten the under-section of the bangs and combine it with the underlayer to frame your face with blonde when the bangs are swept back.
8. The Hidden Bun: For a sleek updo, twist your hair into a low or mid-height bun. The dark top layer remains smooth, while the blonde underlayer is exposed at the base and interior of the bun.
9. Straight and Sleek: Wearing your hair straight and sleek gives the most subtle look, as the brown top layer completely covers the blonde, only offering a hint of color at the very tips.
10. The Reverse Flip: Flip your hair over to the opposite side of your natural part. This sudden shift in volume and direction will dramatically expose the blonde underlayer.

Essential Maintenance for Your Blonde Underneath

Lightening dark brown hair to blonde requires significant lifting, which can lead to damage and brassiness. Proper aftercare is non-negotiable to keep your blonde vibrant and your brown healthy.

The Brassiness Battle: Purple Products

The most important step in maintaining any blonde, especially one against a dark base, is controlling yellow and orange tones.

• Purple Shampoo and Conditioner: Use a high-quality purple shampoo (also known as a toning shampoo) once a week or as needed on the blonde sections only. The violet pigment counteracts the unwanted yellow tones.
• Deep Conditioning Masks: Bleached hair is prone to dryness. Incorporate a moisturizing leave-in treatment or deep conditioning mask into your routine to keep the blonde fortified and healthy.

Protecting Color and Hair Health

• Minimize Washing: Try to alternate wet shampooing with dry shampoo to prevent the blonde from fading and drying out.
• Heat Protection: Always apply a heat protectant spray before using heat styling tools like flat irons or curling irons. Bleached hair is more susceptible to heat damage.
• Professional Toners: Schedule regular appointments with your stylist for a toner refresh (glossing treatment). A toner is essential for keeping the blonde shade exactly where you want it (ashy, icy, or golden) without having to re-bleach the hair.
