I Waxed My Upper Lip Last Week. I'm Now Scared That The Hair Growth Is Going To Get Worse. I Wish I Hadn't Done It. What's The Re-growth Like After Waxing? Will It Grow Back Worse? I'm So Worried.

The hair growth will not worsen.  The skin will be irritated and red and you can go to a drug store or beauty supply place and buy a soothing lotion (I believe it's called a calming lotion) to apply to the skin afterward.  You'll find it where they sell Nair© and other hair removal products.  I've even used an antibiotic cream afterward to stop the irritation.  Don't worry at all.

Relax, it doesn't get worse.  If it did, then people wouldn't do it.
Always use a moisture cream on area afterwards.  ;-)

The regrowth after a wax, is the same as is was before you waxed. When you shave, the hair grows back thicker and faster. Waxing pulls hair out by roots, forcing the hair follicles to grow no difference. Don't worry darling, I wax my upper lip and thighs, and shave everything else. In comparison, the hairs that I wax off, grows back in two weeks when the hair that I shave grows back within days.
