What is the secret to a smooth armpit?

Wax or nair.

lol(: its what all my friend call me, aha

What about waxing? If done properly it won’t irritate your skin.

Or hair removal cream? I find that hair removal cream works better than shaving. However be careful, it could irritate the sensitive skin there.

Another thing that people do is bleaching, but considering it is the hair under your armpits, you’ll probably end up having to do it everytime the hairs grow out, which could become annoying.

Well use your regular razor and soap (or whatever you normally use), I use soap. Shave on a downward motion, upward motion, and left to right, and right to left. You may think it will hurt but it doesnt. Its what your sopposed to do. Someone told me that and I was like no way, that cant be!! but it is. lol

See your armpit hairs grow in all directions so if you only shave one way your going to still have those other hairs that grew in from other ways.

I hoped I helped you, and dont worry a lot of other people have that too!
