3-in-1 Formula: The "3in1" in the name typically means it serves as a shampoo, conditioner, and lice repellent all in one. This makes it a convenient and multi-purpose solution for dealing with lice infestations. It is formulated to kill lice, remove their eggs (nits), and condition the hair.

Active Ingredients: The shampoo's effectiveness comes from its active ingredients. A key ingredient is Permethrin, which is a synthetic insecticide commonly used in anti-lice treatments. It also contains natural oils like Rosehip Seed Oil, Neem Seed Oil, and Tea Tree Oil, which are known for their lice-repellent properties and for being beneficial for scalp and hair health.

Gentle on Hair: The formula is designed to be gentle on the hair and scalp, preventing harsh reactions and leaving the hair soft and fresh. It is often described as being non-chemical and free from harsh smells.
