Garnier Olia Hair Colourants
  • Garnier Olia Hair Colourants FAQs
  • Garnier Olia Hair Colourants FAQs
  • What if I've got dry hair?
  • You may need to vary the development time as dry hair tends to absorb more colour and get darker results.
  • What if I've got different colours in my hair?
  • If you have different colours in your hair due to previous applications, the end result may vary depending on your chosen shade. Bear in mind that natural roots will need longer development time than ends.
  • Will my highlights effect the results?
  • Your results will be affected by both your natural colour and dyed colour(s).
  • Can I use hair colour over existing colour or highlights?
  • Yes but the results will vary depending on the colour you have chosen.
     
  • What if I have long hair?
  • Depending on the length and thickness of your hair you may need to use two or more boxes.
  • What if only my roots need colouring?
  • YFor instructions on how to touch up your roots see the instruction leaflet in pack.
  • What if I've got grey hair?
  • Shades with more intense reflects (e.g. reds) tend to deliver less grey coverage than other shades
  • How can I avoid stains around my hairline?
  • Apply petroleum jelly or moisturiser to your skin before applying the colour, then use warm water and cotton wool to wipe away any excess.
  • Can I create an Ombre or Dip Dye effect with Garnier hair colourants?
  • This depends on your chosen colour, natural and existing colour, and technical skill.
  • Do I need to do an allergy alert test?
  • Yes, you must do an allergy alert test 48 hours before every colour application, even if you have previously used the product with no problems. If you react to the test or have previously experienced sensitivity to hair colours, do not go ahead and colour your hair.
  • How long should I rinse my hair for afterwards?
  • Apply a little water to your hair and gently massage to emulsify the colourant. Next rinse thoroughly under warm water until the water runs clear. Pay particular attention to your hairline and behind your ears.
  • How often can I colour my hair?
  • We recommend that you can reapply the colour every 4-6 weeks.
  • Should I use shampoo to rinse out the colourant?
  • No, when you rinse the hair, the colour will act as a shampoo. For best results, use the conditioner after rinsing, and then again when the water runs clear.
  • Which colour will work best on me?
  • Avoid colouring more than two shades darker or lighter than your current colour. If your hair is already coloured, we recommend you only go darker as it's difficult to lighten coloured hair. If you have a warm or olive skin tone, try a warmer hair colour. Cool and rose complexions work well with cooler shades.
  • How do I achieve a really vibrant red hair colour?
  • Achieving a vibrant red result depends on your previous hair colour and natural colour. Choose a shade with intense reflects.
  • What do the shade numbers mean?
  • All Garnier colourants ranges are labelled according to base colour and reflect. The first number is the base number which tells you its lightness (1-10 from black to very light blonde). The second number, after the dot, is called the 'reflect' (1-6 from ash to red) and shows how 'warm' or 'red-toned' the colour will be.
  • Can pregnant women use hair dye?
  • Hair colours can be used when pregnant. Ask your GP if you have any queries.
  • Can I use hair colourant on hair extensions?
  • Hair extensions often have coatings which can act as a barrier to colour taking fully. Perform a strand test to see the likely end result.
