One of its standout features is its comprehensive pest control, as it effectively kills adult fleas, flea eggs, ticks, and lice. This is particularly beneficial for preventing reinfestation, thanks to the Precor ingredient which acts as an Insect Growth Regulator, ensuring up to 28 days of protection against flea eggs hatching.

The shampoo also caters to pets with sensitive skin, thanks to its soothing formulation containing aloe vera, lanolin, coconut extract, and oatmeal. This not only helps in reducing irritation but also conditions and leaves the pet's coat soft, shiny, and pleasant-smelling with a light fragrance. Its protein-enriched formula ensures good groomability, meaning a little amount goes a long way, making it cost-effective.

However, it's important to note that it is not suitable for pets under 12 weeks of age, and care must be taken to avoid contact with the eyes during application. Some users might find the need to repeat the shampooing process every 7 to 10 days laborious, although this is recommended for persistent flea problems. It's a reliable choice for pet owners looking for an all-round flea treatment solution, but those with very young pets or those seeking a completely hands-off approach may need to consider other options.
