Is this product suitable for daily use? Yes, but it’s best for occasional or statement styles due to its strong hold.
Can I use it on wet hair? It’s designed for dry hair application for optimal hold and styling control.
Does it leave flakes or residue? No, it’s non-flaky and washes out easily with shampoo.
