If you've tinted your eyebrows and they're too dark, you can use a clarifying shampoo to help fade the color. Work the shampoo into a lather with warm water and massage it into your brows. Leave it on for a few minutes, then rinse and repeat until the tint has faded.
Alternatively, a normal cleanser and a cotton pad can also be effective in removing excess dye and fading the color.
If you're looking for a more permanent solution, you could try lightening your eyebrows with a brow lightening product or having them professionally bleached.
Remember, it's important to consult with a professional if you're unsure about how to proceed.
