In a bowl, mix together all these ingredients until you obtain a paste. Control its consistency by adding more water (not too much) and its amount, depending on the length of your hair.
Apply the paste to your hair, spreading it only to your roots. For additional nourishing, apply some olive oil on your hair strands, covering the entire length.
Cover your hair with a bath cap and a towel. Thanks to the mustard, the mask will heat and accelerate blood flow, which will make your hair grow faster. Let the mask sit for about 5 minutes, then rinse it off with warm water.
Repeat the treatment one time a week, for maximum 7 weeks, in order to have positive effects.
Shampoo and condition your hair as usual, leaving it dry naturally.
