Fusion Hair Extensions: 101

What’s the method all about, and what do the application, removal, and care processes look like? We break all that and more down right here.

Hair Fusion Tips for the New Year

Hair fusion--or what we like to call Kera-Link extensions--can be a bit daunting to the uninitiated. As one of our most distinguished and enduring methods, Kera-Link requires precision, confidence, and expertise for optimal effects. In other words, there’s little room to make mistakes! That being said, hair fusion doesn’t have to be difficult. If you’re not already a fusion stylist, make it a mission to master this technique in the new year so you can bring even more hair extension clients into your salon.

What causes Kera-Link Slippage?

Kera-Link extensions are durable and long-lasting, if they’re installed correctly. Sometimes you may experience slippage, which is when Kera-Link hair extension strands get loose and fall out. Sometimes this happens when you’re brushing or styling, and sometimes it happens on its own.
