OK, you obviously need a woman to answer this 😉
The only way to possibly do it is to strip all colour from you hair first using a colour remover. Then you will have to do it again to get it as light as you need, then you need to dye it the required shade of blonde. It will not work and you will end up at the hairdressers having it corrected, which will cost you more than it would if you’d gone directly to them in the first place!
When you’ve had it done you won’t be happy with it, you’ll be a lot lighter in the wallet, your hair will be fried and everyone will take the rip out of you anyway!!
Stay natural, it’s way easier and far more attractive……………….
