I want to bleach one section of my hair, but just the tip, how do you do that.?

Question

And if its to just put in a cup of bleach, for how long?

Answer 1

Are you talking professional bleach or regular household? YOu can't just go dipping your hair in bleach. How dark is your hair? If it's dark, you could end up with a fugly color orange, and if it's light and already colored, you could end up breaking the hair off.
Which would you prefer?
My advice would be to go to a salon and have it done professionally.

Answer 2

Go to a salon.
