My 2 children got lice and my pharmacist recommended Nyda because the product does not contain any chemicals. The product proved effective from the first treatment.
A relieved mom
With the entrance to kindergarten, I was told that lice would invite each other. My 5 year old son got lice pretty quickly after school. It made me feel very stressed because I also have a 2 year old son. The pharmacist immediately offered me Nyda because it is chemical-free, which was important to me, especially when it came time to treat my baby. The two children were not disturbed by the treatment, the smell is sweet, even. The effectiveness of the product was total. We fixed the problem very quickly. What a relief!
I thought we were safe but lice showed up at the beginning of classes in the heads of my 2 daughters. Luckily Nyda was here, we did it in one treatment!
My youngest caught lice at daycare. While doing research, I discovered this product that my pharmacist also recommended because it was pesticide-free and effective. After one application , the lice were eliminated. A second was done only as a precaution. In addition, the treatment did not really bother my little guy. I am very satisfied!
