What You'll Learn in This Hair Extensions Guide
What Are Hair Extensions?
Hair extensions are added strands of human hair used to create more length, volume or fullness. When professionally chosen and applied, they blend seamlessly into your natural hair and can be virtually undetectable.
Hair extensions can be used to:
- Add length to shorter hair
- Create fuller, thicker hair
- Enhance shape and structure
- Add subtle color dimension without chemical processing
š· At BRUSH Amsterdam, our color specialists and extensions experts work together to create a personalized plan for the perfect color match and seamless results.
What Types of Hair Extensions Are There?
There are several types of hair extensions available, each designed for different hair types, lifestyles and desired results.
Tape-In Extensions
Tape-in extensions are semi-permanent and applied using ultra-thin adhesive panels. They lie flat against the scalp, making them one of the most discreet and natural-looking extension methods.
Clip-In Extensions
Clip-in extensions are temporary and can be applied and removed daily. They are ideal for occasional wear, flexible styling and extra volume on demand.
Weft Extensions
Weft extensions are placed in rows and are often used to create more density and fuller lengths, especially for medium to thicker hair types.
Other Extension Methods
Some salons also offer methods such as keratin bonds, microrings or heavier sewn-in systems. These methods can work in certain cases, but they are often more invasive and less aligned with a healthy-hair approach.

Which Hair Extensions Are Best for You?
The best hair extensions depend on your hair type, lifestyle, desired result and how often you want to maintain them.
Important factors to consider include:

For example, fine hair often benefits from lightweight methods, while thicker hair can support more density-focused techniques.

How to Better Care for Your Hair Before Bedtime
- Tie your hair into a loose braid or ponytail to prevent tangling
- Use a silk pillowcase to reduce friction
- Never sleep with wet hair
Can You Style Hair Extensions Like Natural Hair?
If you choose high-quality human hair extensions, they can be styled much like your natural hair.
- You can curl or straighten them
- You can use heat styling with proper protection
- You can wear them smooth, wavy or voluminous
Always use a heat protectant and avoid excessive heat to maintain quality.
Can You Dye or Color Hair Extensions?
Human hair extensions can be toned or slightly colored, but bleaching is generally not recommended.
Because bleaching can weaken the hair fibers, color matching is ideally done before application to ensure a seamless blend.

Why Hair Quality Matters
Not all hair extensions are the same. At BRUSH, we work with 100% premium Remy human hair, which keeps the cuticles aligned and intact.
This results in:
- Less tangling
- Better shine retention
- More natural movement
- A longer lifespan
Lower-quality hair may appear cheaper at first, but it usually needs replacing sooner and rarely delivers the same natural result.
