Really? Tweezers feel good to me, lol. But I haven't done that in a min. I use razors.
In cosmetology school, they advise us not to do this, it causes the hair to grow back shorter, and thicker, like stubble. Razors stimulate hair growth...
I say, if you can deal with tweezers, then you can deal with threading. BTJMO... Threading is quick, and costs a little more, but the results are well worth it.
Waxing is also cool, but if you can avoid the nail shop, I would encourage it... They arent the most sanitary places to get your brows done... Whereas if you find a nice spa or salon... You will have a better experience.
I went to a nail shop last summer, and had my brown waxed... She used wax, tweezers and the litte razor thingy...Well when I got up, I was in love with my brows... they were perfect. I went out with my friends, and then came home to wash the make up off... and I only had 1 1/8 eyebrows....

The threading has less of a margin of error in my opinion...
