Your Add-Ons Questions Answered Here
Answers to common questions about our quick add-on services and what to expect.
Our conditioning treatment add-on uses professional masks and targeted ingredients to hydrate, detangle, and strengthen hair. It usually takes 10 to 20 minutes depending on length and condition. Add it to any service for instant softness, improved shine, and easier styling.
Yes — you can add a flat iron or curling iron finish to most services. Please let your stylist know when booking or at check-in. Pricing depends on hair length and complexity; the add-on includes professional heat styling and thermal protection for long-lasting results.
Timing varies by hair length and desired style. A simple flat iron or quick curl finish typically adds 10 to 20 minutes. Complex styling or extra volume may add more time. Your stylist will confirm the expected time before beginning the add-on.
When performed by professionals using heat protectants and proper technique, add-on flat iron or curling services minimize damage. We always assess hair condition first and use thermal protection products. For fragile or compromised hair, stylists may recommend alternative finishes or gentler settings.
We recommend booking add-ons when you schedule your appointment to ensure stylist availability and accurate timing. If you decide at check-in we’ll do our best to accommodate, but availability and timing may vary during busy periods.
Add-on prices vary by service, hair length, and stylist. Conditioning treatments and styling finishes often start at a small fee, typically ranging from $15 to $45. Your stylist will provide exact pricing during booking or consultation based on your hair and requested add-ons.
