STS Smoothing System

The STS Smoothing System is a gentle, formaldehyde-free treatment that softens and elongates curls while preserving the health and integrity of your hair. Unlike traditional relaxers, it doesn’t alter your curl pattern permanently—making it ideal for clients who want versatility without commitment.

This system is excellent for reducing bulk, defining waves, and easing detangling. After application and heat activation, you’ll notice improved smoothness, shine, and overall manageability. It’s a go-to option for those transitioning to natural hair or looking to stretch their texture without compromising bounce or body.
