Client is fascinated with my talent!

There’s no hair that remains better quality for the length of time it stays in someone’s hair as AQUA HAIR extensions and the colors that I match clients needs to seem to be identical to my eye, what an amazing color selection!

FAQ

What tool do I need for keratin fusion installation?

Our Keratin Fusion Gun is designed for keratin bonds. AQUA bonds melt cleanly and securely when applied properly at 200 degrees celsius.

How long does a full keratin fusion install take?

Around 1.5 to 4 hours, depending on the amount of hair and density.

Are keratin fusion suitable for all clients?

They're best for clients with healthy hair and those looking for low-maintenance, long-wear extensions.

How long do keratin fusion last before needing to be removed?

Kerati fusion last 4-6 months without needing move-ups, making them great for long-term wear. They are a one time use, so new hair will need reapplied each time.

Can I mix keratin fusion with other extension systems?

Yes, especially in hybrid installs. Use keratin s in fine areas where tape or wefts aren’t ideal.
