Very good product, although we caught it at the beginning of the lice issue. From the first application, whatever remained is dead. The process written on the box should be followed as it is not for one-time use. However, a tip I can give is that after spraying the entire head, we wrapped it with a towel and instead of the 45 minutes it recommends, we left it for 3 hours. And it worked from the first use.

I bought it for treatment on my little one who has long and thick hair, I did exactly what it says, it had lice until the 3rd day and then nothing until the 7th day. I repeated it on the 10th day and on the 14th day, I found some babies there.....supposedly the treatment ends on the 14th day and I applied it again on the 18th day but found nothing. I will repeat it again on the 21st day and see. The whole family used it as well. The spray, which is for prevention, claims that it doesn't leave any residue, but unfortunately it does. Overall, the scent is not the best, but I understand the reason.
