Recently, we had a family come in who had unfortunately gotten lice from their niece. This is not their first time dealing with this. They actually had gotten it 6 years ago when the children were younger. The nice thing is, the mom had saved her Hair Fairies products all these years and was able to locate and treat her children right then and there. The good thing is that our Hair Fairies products never expire. Hopefully, you will never need to use our products, but to play it safe, it’s always nice to have it in the medicine cabinet if ever needed.
