  • Why are the plates so large?

    Large plates wider than 30cm are ideal for long, thick, very curly or kinky hair.

  • What is the benefit of steam?

    Steam is ideal for thick, very curly or kinky hair. It stretches the hair to create a straightening that stays in place.

  • Why is there a built-in comb?

    The comb ideally positions your hair on the plates of the straightening iron. Thus your hair is straightened homogeneously. Ideal for long, thick, very curly or kinky hair.

  • Can the straightening iron be used on wet hair?

    We recommend using only Wet’N Dry straighteners on wet hair.

  • How do I curl my hair with a straightening iron?

    We recommend using a 2 in 1 straightener (I-curl or straightener curler) to shape curls, because the convex shape of the cap will make your job easier.
    Simply place the hair in the inside the straightening iron as if you wanted to straighten it, and turn the straightener 90°. Slowly pull the straightener down the length of the hair, from the root to the end, and enjoy your beautiful curls.

  • Which temperature is right for my hair type?

    140°C - 180°C: if your hair is fine, damaged or coloured.

    200°C - 240°C: if your hair is thick, very curly or kinky.

  • What is the purpose of the ionic function?

    The ions generated by the straightener neutralise the static electricity that sometimes occurs when hair is brushed. Hair is smoother, softer and shinier.

  • What is the purpose of the ceramic plates?

    The ceramic plates ensure even heat distribution and ultra-soft sliding. Your hair will thank you.

Tip To straighten hair without damaging it, start straightening from the top, and slowly move down the length of the hair. Do this only once to protect the hair fibre.
