Everything for dry hair works after the shower.
This works during it.

Chlorine keeps tap water safe — and lifts the thin layer of oil that lets hair slide instead of catch. VATNARA screws on in front of your showerhead and takes it out before the water touches anything.

• Straw-like hair, greasy-and-dry, the brush that catches — one cause, taken out at the source
• A drop test in every box — tap water turns yellow, filtered water stays clear
• Screws on by hand in five minutes — renter-friendly, comes off when you move
