It's not recommended to use pet shampoo on humans.
* Different skin types: Human and animal skin have different pH levels and sensitivities. Tea tree oil can be irritating to human skin, especially for those with sensitive skin.
* Formulated differently: Pet shampoos are formulated for animals, and their ingredients might not be suitable for human skin. They may contain ingredients that are toxic or harmful if ingested.
If you are considering using tea tree oil for skin care, it's best to consult a dermatologist or a qualified healthcare professional. They can recommend appropriate products and dosages for your specific skin type and needs.
