Wash the hair, ideally with a clarifying shampoo, but if you already have a straightening in your hair it is not necessary to use a clarifying, your usual shampoo suitable for straightening will do.
Dry your hair
Apply the treatment all over the hair, avoiding touching the scalp.
Leave on for 15 minutes to 60 minutes.
coarsely rinse your hair, leaving a little product.
If your hair is extremely damaged we advise you to do a light brushing and stop there. You can also pass a quick straightener at low temperature (to avoid drying out your hair) on each strand.
If they are not extremely damaged, you can let them dry and pass a straightener at is temperature varying between 180 and 200 degrees depending on the condition of your hair.
