How long before I can highlight my hair again?

I just got my hair higlighted yesterday. My hair has been colored so they had to strip it of color first and then add the highlights. I had fine highlights done (light brown on my dark brown hair) and I want to get chunks done to make it stand out more. How long should I wait before I highlight my hair again? My hair is pretty healthy but i don't want it to get damaged because of all the chemicals used. I would appreciate any advice!
