How do you put highlights in hair without it dying?

Hair is dead, but lightening hair can take away moisture. There is no way to lighten your hair without stripping it of moisture. What you can do is condition you hair after lightening it, and make sure to gradually lighten your hair. Try to avoid 40 volume bleach.

Answer

Use a good quality hair dye to highlight your hair--be sure not to exceed the recommended time. Then, use the conditioner as directed.
