Eyebrows are tricky and should only be colored by a professional in a salon. Bleaching eyebrows is risky if you try it alone, because even a single drip, if it falls into your eye, can cause blindness.

You might be able to learn to thread your own eyebrows, by staring on other people, but it's probably more practical either to hire someone who does professional threading or to pluck yours with tweezers yourself.

It generally takes at least 6 weeks to regrow hair. When it comes to eyebrows, this can take longer if you've been overplucking them for a long time.

Women with gray or white hair often have grey or white eyebrows too, and that's a problem because they become nearly invisible and make you look perpetually surprised.

If you do your eyebrows at home, you can stay on top of them with a daily peering into the mirror and minor tweezing when something crops up. If you visit a professional, you will probably want to have your eyebrows shaped once a month or every six weeks, when you get your hair trimmed.

No, you should pluck unwanted eyebrow hair. Shaving isn't as good for several reasons.

Nothing helps eyebrows grow. I know, it's a terrible thing to say, but only God can make an eyebrow. Well, actually, eyebrows grow because of hormones that are responsible for hair growth. There are only a few reasons people lack eyebrows: hormone problems; chemotherapy and radiation for cancer treatment, which cause your hair to fall out everywhere; eyebrow related accidents involving gas burners, drunken friends with razors or overplucking. If you have the money and your eyebrows are irretrievable due to hormones or cancer treatments, you can have them replaced by a cosmetic surgeon, which can transplant hair from your head to where it should be on your eyebrows. This isn't a quick fix: it takes months for the new hair to come in and grow. On the other hand, it's permanent. On yet the other hand, it costs thousands.

If you wax and then rewax the same place right away because you didn't get it all the first time, you may bruise the skin. Also, not holding the skin taut when pulling off the wax strip can pull that delicate skin out and bruise it like that.
