What our customers say
WHY WE CREATED NAIS HAIR
“So no one can tell you're wearing extensions. SEAMLESS 4K Tape-ins have hand-injected hair that mimics the way hair naturally grows from the scalp. 100% natural hair, with the cuticle intact and full ends.”
At last, extensions that look and feel natural.
When the quality isn't there, it shows straight away. This is what you leave behind.
Broken, dry ends
With low-quality hair, the ends thin out and split within a few weeks.
Tangles when brushing
Blends and cheap fibres knot up. 100% Remy hair with the cuticle intact glides smoothly.
Shine that fades after washing
Good hair keeps its shine wash after wash.
Replacing them every few months
Made to last 12 to 24 months, depending on colour and care.
