Head lice and nits are very common amongst young children and they can cause unpleasant itchiness.
To treat head lice, start by washing your hair with regular shampoo and applying lots of conditioner, then comb the whole head of hair while it’s wet with a detection comb.
If that doesn’t work after a couple of weeks, your pharmacist may recommend a medicated lotion or spray to kill the headlice within a day.
