How Do I Match My Natural Hair Color?
Accurate color matching is the foundation of natural-looking extensions.

Identify Your Base Tone
Examine your hair in natural sunlight to determine its underlying tone—warm golden, cool ash, or neutral.
Check for Color Variations
Note differences between your roots, mid-lengths, and ends. Grown-out roots or sun-lightened ends may require multi-dimensional blending.
Blend Multi-Dimensional Hair
If you have highlights,balayage, or varied tones, select 2–3 extension shades to replicate depth and movement.
Place Shades Strategically
For non-uniform color, position darker extensions near the roots and lighter ones toward the ends to mirror natural hair growth.
Pro Tips
What Is the Best Way to Measure for Length?
The right length depends on where you plan to wear your extensions and your desired style.

Measure your natural hair starting 1–2 inches from the scalp to avoid measuring too close to the root.
Extensions should be 1–2 inches longer than this measurement for a blended, natural finish.
Refer to standard extension lengths and their typical placement:
- 16″: Shoulder-length styles
- 18″: Mid-back length (approx. bra strap level)
- 20″: Lower back
- 22″: Waist-length styles
How Does Placement Affect Length Choice?
Your desired placement directly determines the length you should purchase. For example, if you want mid-back length, choose 18″ extensions when measured from 1–2 inches below the scalp.

🟠 Thickness
50-100 grams/ 1-2 packs: Lightweight for adding volume.
