Liscio Thermal Retexturizing System
“Liscio Crystal Straightening System is the foundation for glossy, manageable hair that can support a variety of exciting hair styles. Its gentle, deep-penetrating formula works quickly to straighten curls and waves with more crystal like shine and more softness than ever before. Liscio actively smoothes, repairs and protects hair inside and out, safely maintaining hair’s integrity after repeated processing.
Liscio Crystal is a 100% formaldehyde free permanent straightening product. The active ingredient is AMMONIUM THIOGLYCOLATE. This product cannot be used on hair that has been treated with henna, sodium hydroxide relaxers, or metallic dyes. “
Smoothing uses less heat than straightening, therefore your hair will revert back to your natural state after 6 months.
