No-Rinse Shampoo Cap [Case of 12] - The shampoo cap can be heated prior to use in a microwave. When warming the shampoo cap in a microwave never heat it for more than 15 seconds. Microwave heating times will vary according to wattage. After heating place the shampoo cap on the head (longer hair requires the user to bundle hair on top of the head prior to placement). Massage hair through shampoo cap until hair feels saturated (approx. 1-2 minutes for shorter hair 2-3 minutes for longer hair). Excessive tangles or foreign matter in hair can require longer massage times or the use of more than one shampoo cap to complete the cleaning process. Remove the shampoo cap and discard the cap in an appropriate container. Towel dry comb and style hair as desired. Warnings: Be sure the shampoo cap is not excessively hot prior to placing it on the head. Never apply a hot shampoo cap. Closely monitor shampoo cap heat levels when using on infants unresponsive patients or sensitive-skinned individuals. Remember the wearing of rubber gloves can diminish your sensitivity to heat. For individual use one. Never re-use the shampoo cap.
