Who Are Halo Hair Extensions For?

Signature Syn Halo extensions are suitable for virtually anyone — but they're especially popular with:

• First-time extension wearers who want an easy, beginner-friendly method
• People with fine or thin hair who need a gentle, attachment-free solution
• Busy women who want a quick style upgrade without a salon visit
• Anyone wanting a damage-free alternative to clip-ins, tape-ins, or keratin bonds

Application takes just minutes and requires no professional help. Once you know the technique, it becomes second nature.

Frequently Asked Questions

Are Signature Syn Halo extensions suitable for fine hair?
Yes. Because there is no mechanical attachment to your natural hair, halo extensions are one of the safest and most recommended options for fine or thin hair.

Can I style Kanekalon synthetic extensions with heat?
Kanekalon fibres have specific heat tolerances. We recommend using heat-free styling methods where possible to preserve the fibre quality and longevity of your extension.

How long does a Signature Syn Halo extension last?
With proper care — correct washing, air drying, gentle detangling, and safe storage — your Signature Syn Halo can stay looking salon-fresh for several months.

How do I choose the right shade?
Order in natural daylight if possible. Compare your mid-lengths and ends (not your roots) to the shade swatches. If you're between shades, go slightly lighter — lighter tones blend more forgivingly than darker ones.

What lengths are available?
14", 18", and 22" — available in Straight, Wavy, and Curly textures across all 36 shades.
