Technique® WAVE Concave Thermal conforms to the shape of the head, delivering more comfort and control when styling. Concave barrel shape prevents hair from 'rolling out' during styling, for faster drying and more uniform results. Heat retaining ceramic coated thermal barrel features tourmaline ionic bristles that infuse moisture into the hair shaft and scalp. Heat resistant static free bristles eliminate fly away hair. Hair sectioning pick conveniently stores in the base of the suede-like grip.
