The KeraStraight's family of treatments and styling products will radically transform your hair, leaving it feeling repaired, looking gorgeous & easy to manage. Every product is designed to deliver like no other as a result of combining the latest technology with our commitment to excellence and our passion for gorgeous hair. Whether you’re looking to grow your hair, save time when styling or to smooth out the curl, KeraStraight has the perfect solution for all your hair needs.

KeraStraight is an evolution in straightening and repair. The semi-permanent treatment has been designed to transform even the most difficult hair into stronger, straighter, repaired hair that’s easy to maintain and gorgeous to the touch. KeraStraight is perfect if your hair is dry or damaged, curly, wavy or frizzy or too thick which  takes too long to dry and style. 

KeraStraight is designed to be suitable for all hair types. It straightens & repairs simultaneously, eliminates frizz, strengthens hair to the very last tip and helps with it being humidity resistant. You get all of this with the benefit of it being Formaldehyde free.
