* Protection from stains: Hair dye can stain your hands and fingernails, which can be difficult to remove. Gloves prevent this, keeping your hands clean.
* Irritant protection: Some hair dyes contain chemicals that can irritate or cause allergic reactions on sensitive skin. Gloves create a barrier between your skin and the dye.
* Easier application: Gloves allow you to work with the dye more easily, especially when applying it to the roots or back of your head.
While you technically *can* dye your hair without gloves, it's definitely more convenient and safer to wear them.
Pro tip: Choose gloves that fit snugly but aren't too tight, and made of a material that won't tear easily. Nitrile gloves are a popular choice.
