I dyed my hair dark brown and I really like it. I just want to know for future reasons, how would I go about dying my dark brown hair light brown or dark blonde?

If you want to go from dark brown to dark blonde, your best bet is to pre-lighten your hair and then deposit the desired color.

There is a type of hair dye you can find in most like shoppers stores and it is meant to take dark hair and make it a lighter burnette it's just a matter of looking through the shelves for it. And if you would like it to be lighter than find a blonde you would like after. But if there is anyway going to a salon is the best as they'll make sure it is done just right.

Store bought high-lift hair colors are known to make dark hair brassy, so be careful. Hair salons have professional products that may lift hair color a few shades lighter, but if you want to go more than 3 shades lighter, you will need to pre-lighten the hair then add the selected color to achieve results. You should consider getting your hair professionally done.
