Frequently Asked Questions (FAQs)
1. What is a smoothing conditioner?
Smoothing/Straight Hair: extra moisturizers and smoothing agents help seal the cuticle and provide a smooth start for your straight hairstyle. Curly Hair: conditioners that are formulated for curly hair are typically very moisturizing and make an extra effort to reduce frizz.
2. Does conditioner make hair smooth?
Conditioners smooth and detangle the hair, which, therefore, helps reduce breakage and split ends — and that's precisely why New York City-based hairstylist Chuck Bass recommends conditioning every time you shampoo in order to add moisture back, as well as to soften and detangle.
