Nothing could be easier than getting started!Start by washing your pits. After drying them well, consider applying a drop of oil to moisturise the hairs. Then test your dye on a small part of your armpit, and if it is conclusive and doesn’t cause irritation, apply your dye on all of the hair. Leave it to set, and TA-DA! Your armpit hair, which used to be so sad and dull, is now glowing more than ever!So, ready to test out this trend this summer?
