Silk Band Galore Bonnets are the best way to preserve your hairstyle. The band in the front secures your edges and the edges of frontals and closures. The bonnet in the back protects the rest of your hair. Silk is better for the hair and prevents the hair from matting, tangling, and popping off throughout the night. The silk band bonnet keeps everything in-tack while you sleep and makes your styles last longer.
