It is therefore advisable to replace this method with the wet combing has been validated by a Belgian team provided you follow five rules simple. To view the most lice and dandruff distinction, simply apply a detangler on wet hair, to comb with a fine toothed comb and make careful observation with a magnifying glass ( ten times). Its effectiveness was demonstrated during a screening of 260 students from two to twelve years. In this study, the prevalence of lice searched by combing wet is 22%.
