Discovered head lice in two daughters heads twelve days ago. Firstly applied shampoo to kill lice and then daily applied homeopathic shampoo and tea tree oil. After sevn days I applied the chemical shampoo again just in case and every day , morning and night I picked the eggs out with my fingers - lovely. The eggs have reduced in number and size and then tonightafter washing hair I went through with nicomb and found three lice, not eggs. Where am I going wrong? Only consolation is that I now have greater understanding of the phrases nitpicking and going over something with a fine tooth comb- I can't believe how time consuming the whole process is. My daughter has just asked what she can take into school tomorrow for show and tell and my husband suggested she take the nit comb in . Any advice most welcome
