Fusion Bonded Hair Extensions NYC

The Kasthetix Difference

Customized To You

Fusion hair extensions near me searches often lead clients to Kasthetix Beauty and Salon when they want discreet, long-lasting k-tip hair extensions designed to blend seamlessly and wear beautifully over time. K-tip hair extensions (fusion hair extensions) are installed with care focusing on the lifestyle maintenance, blending, and wearability in a salon studio in NYC that understands both aesthetics and lifestyle. This method is ideal for clients who want added volume, length, or both—without frequent salon maintenance or visible attachment points.

Hair Extension Questions, Answered

Which method of extensions should I chose?

Great question! Before any install is done, we always have an in-person consultation to best determine which method is the best fit. Beaded sewn in wefts are great for people who want easily removable extensions, spend less time in the salon and want to add volume, length or both. Keratin Tip extensions are great for clients who want longer lasting extensions, a near invisible attachment point, and less in salon maintenance. Keratin (fusion) bonded extensions also are the most natural and longest lasting. Many clients chose a combination of both to suite their needs.

How do I book my first appointment?

We can't wait to have you — please click on the buttons above to request an appointment or consult via text or email, which will directly open up in that format.

Should I book an in-person or virtual consultation?

If you are getting a color correction, transformation, or extension service, in-person consults are required. However, if you are getting a highlight, single process, or glaze/toner, a virtual or in-person consultation is totally fine. The point of the consultation is to determine the correct service to book and briefly discuss your goals.

I'm not certain of what service I should book — what do I do?

No worries at all — that's exactly what consultations are for. Reach out via text or email and we'll point you in the right direction before you book anything.
