How To Use: 1. Begin with damp, styled hair ( 75 dry), and create 2-4 sections. 2. Wrap one flexible end of the Length-n-Lock around the very top of a hair section, ensuring the hooked side faces inward and overlaps the opposite side. 3. Hold the section (hair net) with one hand, then with the other hand latch the hooks into the mesh holes from top to bottom, ensuring a snug grip. 4. Wrap the bottom of the Length-n-Lock slightly above the end of the hair section (roll up before wrapping if needed). 5. Repeat steps 1-4 on the remaining hair section(s). Air-dry overnight (recommended), blow-dry, or use a hooded dryer until hair is 100 dry. Then remove the Length-n-Locks shake fluff to restore volume.
