A hair color mistake can be upsetting, but it does not mean your hair is damaged forever. If you wonder what is a corrective color, it is a professional salon service that fixes unwanted hair color issues like uneven shades, wrong tones, or unexpected results. A skilled stylist checks your hair and chooses the safest way to improve its look. With proper care, corrective color can help restore balance, protect your hair, and bring back a natural, beautiful appearance.
