First, read the English article below.

Coconut oil in particular strengthens the proteins in your hair but avocado and argan oils are also great for looking after damaged or treated hair. Starting before you bleach will help your hair tolerate and absorb the bleach better. In particular, the night before you dye your hair, melt half a cup or more of coconut oil in a saucepan or in the microwave. Wait for it to cool, then massage it into your hair. Sleep with a plastic shower cap over it, or cover your pillow with an old towel.  You'll get pretty oily, but don't worry: coconut oil is good for your skin, too. If you're bleaching at home, you can re-apply the oil before you apply the bleach. Don't wash it out.  After you've dyed your hair, continue to look after it by applying oil every day or two. Massage the oil into your hair, starting at the ends and ending near the roots. Once or twice a week, apply a mask to your hair. Make a mask at home by mixing any combination of coconut oil, olive oil, yoghurt, honey, bananas, avocadoes, and egg. Blend together and wear in your clean, dry hair for 30 minutes. For best results, start this routine as soon as you know you are going to bleach your hair, and maintain it after you have bleached.  You can also buy professional masks and deep conditioners. Oils such as coconut, argan and avocado are great for healing color-treated, bleached, and fried hair. If you don't have time to make a mask, just massage some oil in, starting at your ends and ending at your roots. Start applying oil as soon as you know you are going to bleach, and maintain it in your routine.
