Are your strands no longer the soft texture of before?

Do they walk dull and motionless? Watch out! You may have damaged hair. A simple way to be sure is to do the knot test on a thin strand of hair. Separate the wick, loop the wires using your supporting fingers, and then release them. Has the knot remained intact or easily dislodged? If your answer is the first alternative, beware: this may mean that your hair is not strong enough to undo the knot alone. But what to do on a day to day basis to give back the strength and hydration needed to keep hair healthy again?

Here you find the answer to this and other questions.
