We make The Drain Claw.
This little drain snake is the easiest, fastest way to unclog bath drains because of hair. It has over 100 small interlocking hooks to grab hair and remove it from your drain. It will pass through pop-ups as small as 1/4" so you don't have to remove the stopper. It will not get stuck in small drains like other snakes with sharp barbs.
If you have slow bath drains because of hair, you will love The Drain Claw.
