About Shade 4 - Chestnut Brown
Shade 4 is a warm chestnut brown, one step lighter than medium brown (3). The hair is 100% Slavic Remy, cuticle aligned and double-drawn, with a naturally straight texture. The warm undertone makes shade 4 flattering against golden, warm, and olive skin tones - the warmth in these brown k-tip extensions lifts complexion rather than flattens it. Shade 4 is one of the most popular brown shades across Europe and the US, and it photographs beautifully in warm light. Our chestnut brown hair extensions in shade 4 stay consistent from bundle to bundle, which matters on repeat builds. Slavic chestnut brown hair in this tone holds up through multiple styling sessions.

Frequently Asked Questions
Q: How warm is shade 4 - does it lean red or caramel?
A: Shade 4 leans caramel, not red. There's a soft golden warmth in the tips under sunlight, but no red pull in everyday lighting.
Q: Can shade 4 be toned cooler if needed?
A: Yes. A pearl or ashy toner at low developer can knock back the warmth without damaging the strands. Retone every 6-8 weeks as needed.
Q: Will shade 4 match my client's natural warm brown?
A: Usually yes - shade 4 is one of the most common natural brunette tones worldwide. For exact matches, request a color match consultation.
Q: How many bundles do I need for a full head?
A: Most clients need 3-4 bundles for a full head K-tip install. Fine or short natural hair may need only 2.
Q: Can I add highlights to shade 4 without damage?
A: Yes. Slavic hair lifts cleanly with 20 vol developer and foil or balayage technique. Use a bond protector and let the salon handle it - avoid home lightening.
