The subject of hair removal is as varied as it is long!
It represents a life long struggle for some and for other they seem to find their utopia very quickly but most it is a long, hard struggle.
First of all Hair grows naturally, the body is comfortable with it and whatever the mind thinks the body will try to repair or compensate for the damage created to the hair process.
The second problem is that hair removal/retardent products are designed and registered for use in natal females not males.
The data relates to natal females not males and so the results will be affected by that, add in a little bit of interpretaion, marketing and generic presentaion of ‘some’ evidence and it often leads to disapointmnet.
I know that this is not what you want to read.
We hear of someone’s success and desperately try to have some of that too.
