Does Serum Cicanuit Hair Serum protect from heat styling tools?
No, it is designed to be used at night on wet or dry hair to air dry and penetrate hair fiber overnight. For heat protection before a blow dry, we recommend Cicaplasme Hair Primer that provides up to 450-degree F heat and styling tool protection.
What’s the difference between Serum Cicanuit and Cicaplasme?
Serum Cicanuit was specifically designed to recover blonde hair overnight. Cicaplasme is a universal fortifying heat-protecting serum – up to 450 degrees F – that reinforces the hair fiber to protect against external damage and aggressors.
Can I apply Serum Cicanuit Hair Serum on the scalp?
We do not recommend applying on the scalp. Apply Serum Cicanuit on lengths & ends for optimal results.
