27. Go To The Salon Every Two Months
While you can totally grow out your gray hair without going to the salon once, it will be more of an awkward, clunky stage. If you want to avoid that, prepare to go to the salon once every two months. This way you can get a length trim and let your roots keep growing, and get a highlight and lowlight touchup to make the whole process look seamless and bright. Maintenance is key until your naturally silver locks take over fully.
