The QFit Self-Warming Cholesterol Cap is a deep-conditioning heat cap that boosts the effectiveness of hair treatments, masks, and cholesterol conditioners. Its self-warming, heat-retaining design gently activates conditioning products to penetrate deeper for softer, more moisturized hair. A comfortable elastic band provides a secure, snug fit in a large size that covers most head and hair styles. Ideal for salon and at-home deep-conditioning treatments.
