Yes, repeating the treatment too quickly may increase your child's risk of side effects from the lice treatment, such as scalp irritation. Especially, beware of Lindane, it might kill more than lice. Go naturally, try below tips:
- Apply the mixture of water and vinegar in the ratio of 3:1 on scalp for 12 hrs. The head should then be shampooed thoroughly with head lice shampoo and hot water and then remove nits with a lice comb dipped in hot vinegar. It should be repeated 2-3 times a week.
- Try to remove the live lice and nits manually. Continue to remove nits from your child's head, even if you have to check his head each night for a week or more until you get them all.
- Be sure to wash your child's clothing and bedding in hot water and vacuum to remove lice and nits from furniture, carpets, stuffed animals, car seats, etc.
- Keep the hair short.
