Directions Wet hair completely with NYDA and leave on for 30 minutes. After 30 minutes comb hair carefully and leave hair overnight to dry. The next morning, wash hair out with normal shampoo. Re-check hair for newly acquired lice every 8-10 days.
Warnings Because some of the ingredients are inflammable NYDA must not be used near open fire or incandescent objects (for example also a hair dryer). Keep NYDA away from heat and ignition sources and do not smoke during the treatment.
