This is hair chalk for coloring your hair. Since it doesn't dye your hair, you can easily add color just for the day. It's great for live performances, events, Zoom meetings, festivals, video calls, and Facetime. It's also popular for being fun to use in online university classes. Because it's chalk, the color may transfer to other things that come into contact with your hair. Be especially careful with white clothing, bags, etc. The darker your natural hair color, the longer it may take to apply the color. Those with brown or blonde hair will find it easier to apply color compared to those with black hair. Great for Halloween, Christmas, and New Year's outings.
