Beard dye and regular hair dye are similar in many ways, but there are some differences that are worth noting.
First, beard dye is specifically formulated to be used on facial hair, which is coarser and more sensitive than the hair on your head. This means that beard dye may be gentler and less irritating than regular hair dye.
Second, beard dye usually comes in smaller packaging compared to regular hair dye because the amount needed for facial hair is typically much less.
Third, beard dye may have different color options specifically tailored to men's facial hair, such as shades that match natural beard colors or colors that are popular in men's grooming trends.
Overall, while there may be some minor differences between beard dye and regular hair dye, the two products are quite similar. However, it's important to follow the instructions on the packaging and use the appropriate product for the type of hair you are dyeing
