Lyclear Extra Strong Shampoo contains an active ingredient known as permethrin, which is effective in killing lice and their eggs. Permethrin is a synthetic chemical that works by disrupting the nervous system of the lice, leading to their death.
The shampoo also contains other inactive ingredients that contribute to its texture, appearance, and overall formulation. While the exact list of inactive ingredients may vary slightly depending on the manufacturer, these ingredients are typically chosen for their safety and compatibility with the active ingredient.
It's important to note that individuals with known allergies or sensitivities to any of the ingredients in Lyclear Extra Strong Shampoo should exercise caution and consider alternatives.

Can I use Lyclear Extra Strong Shampoo as a preventive measure against head lice?

Lyclear Extra Strong Shampoo is a topical product, and it is unlikely to interact with other medications taken orally or applied externally. However, if you are currently using other scalp or hair treatments, it's advisable to consult a healthcare professional or pharmacist to ensure there are no potential interactions.

How should I store Lyclear Extra Strong Shampoo between uses?

To maintain the product's effectiveness, store Lyclear Extra Strong Shampoo in a cool, dry place and keep the cap tightly closed. Make sure it is out of reach of children. Avoid exposing the product to excessive heat or direct sunlight, as this can potentially alter its properties.
