It's Friday, which means two things: We all have that Rebecca Black song in our heads, and it's time for us to answer a reader question. Today, we're tackling a beauty query from our Facebook pal Suzanne Pyles:
But we think this question brings up another question: Why do overplucked hairs stop growing back, anyway?
"Overplucking of the brows can lead to a diminution in the size of the hair follicle, thereby making the new growing hairs smaller and finer as well. This happens when people wax a lot," explains Dr. Carolyn Jacob, a Chicago dermatologist. "Older women tend to lose eyebrow hairs, too, so you don't want to make your brows thin when you are younger. It doesn't look right, and you wont have much, if anything, to work with when you're older."
Onto the real question here: Can the eyebrow hairs you accidentally made disappear ever grow back?
"Sometimes, if the plucking is too forceful or if there is chronic irritation or inflammation, this can lead to damage or scarring of the hair follicle, thus a new hair does not grow," says Dr. Paradi Mirmirani, a dermatologist practicing in Vallejo, Calif. "This is a rare occurence, but once the follicle is damaged it is permanent. There is no treatment other than hair transplantation that would lead to successful regrowth of another hair shaft."
Short of hair transplantation, you could always consider permanent makeup, although we hear that doesn't always work out so well.
