Apply a small amount of an alcohol-based product such as mouthwash, after-shave or fragrance to cotton wool and gently rub affected areas. Follow up by wiping with water and applying a little face moisturiser. To prevent colour staining for future applications, apply a little moisturiser or Vaseline to your hairline before you apply the colour, ensuring you do not get it on the hair as it can also prevent the colour from taking in those areas.
