Q: What is a tail comb used for?
A: Sectioning, mostly. The pointed tail parts hair cleanly and lifts sections for colouring, styling or pinning, while the teeth smooth as you go.
Q: How do you section hair with a tail comb?
A: Use the tail to draw the parting first, then lift and clip the section away before moving on. Clean partings are what make the finished style look neat.
Q: Can you use a tail comb on wet hair?
A: Yes, and it is often easier. Wet hair parts more cleanly, though it is worth detangling with something wider before using the fine teeth.
