Any method of hair removal can be performed from home and there are numerous options when it comes to bikini hair removal. If you want a permanent option then I suggest using an IPL hair removal system. It's totally safe and can be used at home.
If you are looking for something more affordable that will have better and longer lasting results than shavin or the use of a hair removal cream, you can try waxing or an all-natural method called sugaringwhich actually hurts much less than waxing.
Here is a hair removal blog that shows all of the most effective hair removal methods available today.
