Hi Long Hair,
Like wat Furlin hve said,abit painful..but for mi,oni certain areas tt r painful....
it will depends on how fast yr hair grow out..if it grow out fast,then hve to go back in one mth's time,but if it grow out slow,then oni need to go back in 6 wks time.
some pple will hve some side effects,the side effects r itchiness,redness and will hve dark patch at the underarm.but all these will be gone in a few days.
