Tips for using shampoo bars: Wet your hair and rub the bar over the hair to create a creamy lather. You will need to use plenty of water. If you feel there isn’t enough lather, just add more water! Some people like to use a diluted cider vinegar as a conditioning rinse. Put a splash of vinegar in a jug of water and use it after rinsing all of the shampoo out of your hair. As you pour it over your hair you will notice how your hair becomes immediately soft and silky. Then do a final rinse. Avoid contact with eyes as it will sting. If you get it in your eyes rinse with plenty of water.
