tweezing the hairline

Hi all. I was wondering, how long does it take to grow back hair on the hairline after tweezing? Also, is it true that the hair will come back thicker?

It will take anywhere from 6-16 weeks for the hair to grow back. Continuous tweezing, over time, COULD cause the hair structure to change, but this is not an exact science do to many variables involved in each unique human being hair situation.

does it really take that long? I heard that it only takes 4-6 weeks.

The time depends on the size (diameter) of the hair. When hair is thicker, it takes less time to reappear.
After being pulled under the hair, the larger hairs appears first , then the hairs of medium size, and finally the fine hairs.

You may want to consider threading if you are not looking for permanent removal, which I would recommmend instead (i.e. electrolysis).
