On the one hand, the comb facilitates the diagnosis of head lice since it can be easily checked for lice or nits after each combing. The lice comb can also be used to quickly and comfortably comb the killed head lice from the hair. The NYDA® lice and nit comb has been clinically tested and has particularly tight and long metal tines. The tines are rounded at the ends and are particularly gentle on the scalp. The angled shape facilitates application.
