The No Knot Co Flexi Detangler Brush (£13.50) is the brand's newest addition to its fan-favourite line of flexible detangling brushes. Made with wavy, curly, and coily hair textures in mind, the Flexi Detangler's soft bristles gently break up knots without any pulling, tugging, ripping, or shredding — all of which can cause damage to your hair.
