It takes 50 years approx because i shaved mine i am sixty now, and it is still a bristle of hair, it takes so long because the skin cells break every time a hair comes through therefore damaging the hair - reproduction cells. You will get cancer if you shave your eyebrows, says my doctor.
You can keep your unibrow under control by plucking the stray hairs as they grow back.
wait till they grow back... drew them back on .... get fake ones...
It does grow back, however, the rate at which it grows is entirely dependent on the person.
Monobrow or a Unibrow:)
Yes, hair will grow back if shaved off. If it didn't, no one would have a beard or mustache.
YES ! (: it should.
Either she keeps on shaving, or her hair will grow back to the point they were before she shaved, simply.
No. It'll grow back just as it was before you shaved it, but the stubble will feel a bit coarser at first.
Your hair will grow back at the normal rate it always grows at, provided you aren't balding.
You can wait for it to grow back or get a fake beard in the meantime.
Yes, they will grow back. (yes but that's not my question i was gonna say that does it grow the same way you idiot! and this is the person that put in the question and when do they grow back if you know so much?) I imagine that it won't grow back how they was.. If you wait until it grows back, then wax/pluck or shave it into place again. [careful not to shave half of your eyebrow again if you do shave. XD]
If you have shaved off or lost your hair due to illness, the hair takes on average one month to grow back half an inch.
