Color correction is a comprehensive hair coloring service that can rectify previously dyed hair and enhance its overall look and quality. Each session can last up to 5 hours and typically involves balayage, three- five personalized hair color and toner formulas, deep treatments like olaplex and collagen to prevent damage, and a haircut and styling to remove any spit ends and smoother-looking hair. Up to $30, additional fees may apply depending on hair length, texture, and density. All sales are final.
