Fancy a new colour but don’t want to go to the hairdresser’s? These days, you can reinvent yourself in so many ways with home hair dyes and achieve practically the same result as you’d get with salon dyes… as long as you choose them well and know how to use them. Here are our tips for getting your home hair colour right every time!
1. Find the right formula
You’ll find three types of hair colours in shops:
• Temporary colours, which gradually wash out over 6 to 8 shampoos: these are gentle on the hair and contain no ammonia or peroxide. They won’t lighten the hair and they don’t cover greys, but they are perfect for obtaining pretty highlights and giving your hair a natural sheen.
• Semi-permanent colours, which last 6 to 8 weeks and usually contain peroxide: they partially cover greys and can make your hair one shade lighter.
• Permanent colours, which contain ammonia: these are the only ones that truly change the colour of the hair and cover greys completely. With these, everything is possible, but they need to be refreshed every 2 months to avoid unsightly regrowth.
Make the right choice based on the colour you wish to obtain and the amount of greys to cover!
2. Choose the right colour
When colouring your hair at home, it’s best to stay reasonable: for a natural result, don’t go more than two shades lighter or darker. If you have dark hair but want it platinum blond, you’re better off going to see a professional.
But properly identifying your natural colour is tricky! We always tend to see our hair as darker than it really is. Place a strand of your hair next to the colour chart provided in the shop, and if you find yourself hesitating between two shades, choose the lighter one.
Make sure to choose a colour that also suits your skin tone: reddish and copper shades suit pale skin, ashen colours work well with pinkish skin tones, and warm browns are perfect for olive skin. Pick the shade that suits you best.
3. Apply the colour like a pro
Hair colouring is chemistry and it requires precision: don’t even think about improvising or trying risky mixtures! Before starting, make sure everything you need is within reach: the contents of the colouring kit, but also a towel to protect your shoulders, a brush, a comb, hair clips to hold your hair as you apply the colour, and a timer or a watch.
Here’s a tip to avoid colour stains on your skin: apply Vaseline or some other rich cream along your hairline. If you accidentally get some colour on your skin, this will prevent it from penetrating.
Then, follow the instructions to the letter: put on the gloves, mix everything in the right order, apply to wet or dry hair as instructed, etc. Apply the colour to the roots, section by section using a tail comb, then apply to the rest of the hair. Use two mirrors to check the front and back to ensure you haven’t missed a spot. Leave the colour in for the recommended time: if you don’t leave it in for long enough, you will not achieve the desired result. Conversely, if you leave it in for too long, you risk damaging your hair. To finish, rinse carefully and apply the conditioning treatment provided with the colour, or a treatment specially formulated for coloured hair.
4. Take good care of your hair
Hair colours, and particularly permanent ones, can be harsh on the hair: don’t ever use them on damaged or dry hair, or on hair that has been weakened by a perm. A few days before colouring, give your hair a deep nourishing treatment by applying a mask or hair oil.
After colouring, use shampoos that are specially formulated for coloured hair. These will help keep your hair shiny and your colour vibrant. And once a week, apply an intensive nourishing hair mask for deep conditioning. Lastly, to protect your hair fibre, wait at least one month before applying another colour.
