Please use this system as follows:
1. Lice oil - 3 - 4 times a week - 2 times a week on non hair wash days - use 1/4 teaspoon directly on scalp and comb the hair normally. Once / twice a week, on hair wash days, apply oil generously on scalp + hair - after 20 minutes, comb out all lice and nits. They will appear sluggish / stunned due to effects of the oil.
2. On hair wash day, 30 minutes before hair wash, make a thick paste using water and the Anti Lice hair mask. Apply in sections onto well oiled , detangled and combed hair. Concentrate on the scalp and cover it completely. Put on a shower cap to keep the mask moist for as long as possible.
3. Once the mask starts to dry out, rinse out with plain water and follow up with anti lice hair wash. Anti lice hair wash should be mixed with water to form a moderately thick paste (like you use shikakai).
For 2 children, one kit should be more than enough.
