I have been using the Fairy Tales Lice Rosemary Repel products on my daughters hair for years and now they have reformulated them to include more effective ingredients to prevent lice. The line includes Rosemary Repel Shampoo, Conditioner, Conditioning Spray, Styling Gel and Hair Spray. Through clinical testing Fairy Tales has improved its formula and has made it 30% more efficacious than the previous formula. The products contain a blend of rosemary, citronella and tea tree oil which are known to help prevent lice. They also include jojoba, sugar cane and chamomile which help maintain a healthy scalp. Fairy Tales products are safe to use daily for all ages and are free of sulfates, harsh chemicals and toxins. As an added bonus they are gluten, dairy and nut free. The products smell as good as they work. My daughter has never had head lice and I’m not about to change that now! I highly recommend this product not just for lice prevention but also for beautiful healthy hair.
