Massage about 30 ml 1% gamma benzene hexachloride shampoo (Gambex or Quellada shampoo) into the affected areas and leave on for 5 minutes before rinsing off thoroughly. Benzyl benzoate (Ascabiol) 12.5% (i.e. diluted 50:50) can also be used and applied to the whole scalp overnight and then washed off in the morning. Do not get the lotion into the eyes as it burns. Pyrethroid shampoos (Lyclear and Nitagon) are also effective in killing lice. The nits can be removed with a fine comb. Using hair conditioner after washing the hair helps to remove the nits as it makes the hair slippery. It is not necessary to cut or shave the hair off although this is an effective treatment. It is best to treat the whole family and look for nits in friends. Oral antibiotics should be given if impetigo is present. Do not share hairbrushes and combs.
