Firstly, put a towel on your shoulders to avoid staining your clothes. Secondly, make sure you shake L’Oréal Paris Magic Retouch Root Touch Up really well before using it. Thirdly, direct the precision applicator to the area and maintain a distance of 10-15cm. Then, spray a little bit of product across the roots and gently comb the hair to distribute evenly. Lastly, let it dry for one minute without touching your hair with your hands and then you’re ready to go. If you stain your hands or clothes, don’t worry, as the product will wash out easily.
