Head lice treatment takes time, even with the right shampoo. Once the shampoo is applied and rinsed out, a few steps usually follow. Knowing what to watch for after the first use may help maintain progress and avoid further spread among others in the home or at school.
Dead lice may be visible
After rinsing the head lice shampoo, you may notice dead lice in the hair or on the scalp. This is expected and usually means the shampoo has started to work. These can be removed using a fine-tooth comb. If no lice are seen, it does not always mean the treatment failed, as some might be rinsed away during washing.
Nits may still remain
Shampoo may kill live lice, but nits (lice eggs) often stay attached to the hair shafts. These appear as tiny white or yellowish dots close to the scalp. A lice comb should be used to remove them. This process might want to be done daily for a few days after the first wash.
Mild scalp irritation may occur
Some shampoos cause a slight tingling or itching on the scalp after use. This may last for a short time and may be due to dryness or the effect of the product. Scratching should be avoided to prevent breaking the skin. If irritation becomes strong, speak to a healthcare provider before the next treatment.
Itching might not stop right away
Even if lice are gone, itching may continue for a few days. This is not always a sign of live lice. The scalp may still react to bites or leftover residue. A second round of shampoo after a week helps target any lice that hatched from remaining nits.
Regular checks are necessary
After treatment, check the hair every day using a lice comb. This helps spot any live lice early. It may also show if the shampoo worked fully or if another round is necessary. Keep hair tied back if possible, especially in group settings like schools.
Repeat treatment is often suggested
Most head lice shampoos come with advice to repeat use after 7 to 10 days. This step may stop the cycle by targeting newly hatched lice. Skipping it may result in lice returning.
Cleaning is still part of the routine
After treatment, wash pillowcases, hats, combs, and other personal items. These simple actions support the effort to keep lice away from the hair after the initial treatment.
