Is your hair damaged, frizzy or too curly? Or perhaps it’s unruly, dry or too thick?
We have the answer…
KeraStraight’s Ultimate Treatment leaves your hair healthy, stronger and smoother. Just imagine having soft, manageable hair from the roots to the tips.

How does KeraStraight work?
Using advanced protein technology KeraStraight transforms the shape and condition of all hair types. It rebuilds the keratin and adds strength, elasticity and moisture, leaving your hair with added strength, vitality and shine.
This smooth, soft and straighter finish lasts for up to 4 months, gradually fading from the hair.


Why choose KeraStraight?
It’s Formaldehyde free, unlike many hair smoothing treatments, which means it’s kinder to your hair and the environment.
Suitable for all hair types, it strengthens and repairs hair to the very last tip, while eliminating frizz and making hair more resistant to humidity.

What’s in KeraStraight?
Triprotamend
Triprotamend contains proteins with small molecules that diffuse rapidly into the cuticle and cortex, reacting with the hair’s natural Keratin. These fill in defects, while restructuring and strengthening the hair. As the hair is ironed, it seals in this improved structure for up to 4 months.
Hydroryzin
Hydroryzin is packed with rich hydration ingredients to ensure a great moisture balance within the hair.
Botaniset
Botaniset is a compound of African and Amazonian fruit and plant extracts, chosen to help keep the treatment sealed in for maximum performance and longevity. If you find your hair hard to manage, or have dry, frizzy or damaged hair then
