Here's why:
* It's a solvent, not a dye: Rubbing alcohol is designed to dissolve things, not to deposit color. It might actually strip color out of your hair if used frequently.
* It's too harsh: Rubbing alcohol is very drying and can damage your hair and scalp.
* It doesn't contain pigment: Hair dyes contain pigments that bind to the hair shaft to change the color. Rubbing alcohol lacks these pigments.
If you're looking to change your hair color, it's best to use permanent or semi-permanent hair dyes designed specifically for that purpose. These products contain the necessary pigments and chemicals to safely and effectively color your hair.
