I noticed a slight difference in the speed of growth but not enough to not have to shave my chin daily... I decided to go for laser hair removal... BEST thing I could have ever ever done... I go every 8 weeks ( that is the length of each hair cycle) and I am almost all clear if it all... the ones that are coming through are now so blond they are see through...lol..... my next hair removal project will be the side burns via laser.
