FAQ
Is this the right strength for my hair?
RESISTANT is formulated for medium to thick, naturally curly or frizzy hair; a NORMAL strength is also available for finer, wavy hair.
How long does the straightening process take?
It depends on hair length; shoulder-length hair typically takes around 3 to 3.5 hours in-salon.
Will it over-process my hair?
No, the auto-control technology is designed to stop straightening once a natural straight look is achieved.
How is it applied?
Hair is washed, sectioned, and the cream applied in-salon, left on for the recommended time, then rinsed thoroughly.
What should I use afterwards?
Pair it with the Matrix Opti Care range to help maintain smoother, healthier-looking hair after the straightening service.
