Here's why:
* Permanent marker ink is designed for surfaces, not hair. It contains chemicals that can irritate your scalp, damage your hair, and even cause allergic reactions.
* The ink won't wash out easily. Even if you manage to get the marker out of your hair, it may leave behind a stain that is difficult to remove.
* It can be extremely difficult to remove. Attempting to remove it yourself may further damage your hair.
Instead of using permanent marker, try a hair dye specifically designed for your hair type.
If you accidentally got permanent marker on your hair, it's best to consult a professional hairstylist or a dermatologist. They can advise you on the best course of action to safely remove the ink and prevent further damage.
