Customized To You
What Clients Are Saying
Three Reasons Clients Keep Coming Back
Color Corrections Require Expertise
Specialized Expertise- Hair color corrections are time intensive, product intensive, and require expertise. .
Built Around Your Hair, Not a Formula
Customized to each client, no two color corrections are the same. Every formula and plan is built around the clients current hair condition, lifestyle, history and desired outcome — whether that is a seamless, lived-in highlight, a dramatic copper, or a bold change that makes a statement.
Results That Last
Results that last, clients love us as our results look great in the salon, and two months from their appointments. Clients come to Kasthetix because we understand the full picture — the color, the maintenance, and the longevity.
How It Works
We Talk First
What you want, what your hair will actually do, and how much upkeep you're up for. The plan is built around all three — not just a photo on a phone.
Painted by Hand
Lightener and foils intentionally placed, section by section — no autopilot sections, no one-size placement. This is where the dimension comes from.
Toned & Finished
Glossed to the exact shade you're after — cool, warm, or in between — then cut and styled so you leave ready, not handed a mirror and rushed out.

Hair Coloring Questions, Answered
Do I need a toner and what is it?
A toner is a way for colorists to neutralize any unwanted undertones during a color service, and reintroudcing the color or hue we want to see as a result. We usually do recommend getting a toner as it is included in our highlight and single process services already.
How long does the color last?
Great question! A professional hair coloring service is meant to last depending on the desired outcome. For single processes, we recommend a retouch appointment every 6 weeks, highlight appointments can last three to six months! Our hair coloring and planning is catered to a combination of lifestyle factors./p>
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.
