Here's why:
* Glow stick dye is temporary: The dye in glow sticks is designed to be temporary and washes off with soap and water.
* Dark hair pigment: Dark hair has more melanin, which provides a natural barrier against color absorption.
However, if you are concerned, it's always best to err on the side of caution:
* Test a small area: Apply a small amount of glow stick liquid to a hidden area of your hair and let it dry. If there's no staining after a few hours, you should be good to go.
* Use caution around hairlines: Glow sticks are designed for temporary use, but it's best to avoid getting the liquid directly on your hairline, as it could potentially stain your skin.
If you do accidentally get glow stick liquid on your hair, wash it out with soap and water as soon as possible.
