It really, really depends on your tank. Everyone's tank is going to be different. A lot of good suggestions were mentioned here though.
I've been running two TBS tanks. One is going on three years old and I have not seen any hair algae in over a year. I am overskimming in this tank, though so it could be the lack of nutrients that lead to the lack of algae. I also have several turbo snails running about the tank which might lend to it as well. (They're each over a year and a half old, so I know they're eating something.)
My second tank is going on a year old now on TBS rock. I am beginning to grow small spots of hair algae in various places after a long dry spell of nothing. The hair algae is nothing, though and is kept well trimmed by a chevron tang I have in the tank.
I can't keep turbos in this tank due to some gnarly atlantic hermits that came in with the first half of my rock (When they couldn't pull rock from the gulf side). They eat anything snail-like in the tank and are currently wearing large turbo shells.
Anyway, its really up to your tank balance how to get rid of it. Pulling it out does not solve the problem as to why it is there in the first place. Either you have too much lighting or too much nutrients with little to keep its growth in check. The key is finding that perfect balance.
If you have too much lighting, or are lighting for excessive periods of time and want to keep doing that, its fine, just buy something that will eat it and keep it in check. Turbo snails and herbivores are great. I generally suggest tangs if your tank is big enough. Lawnmore Blennies rarely actually eat the algae as opposed to rip it off, suck out the "slime" algae and spit out the hair stuff to grow somewhere else.
If you have too many nutrients (generally tell-able by the amount of nitrates in the water) you may want to cut back on feeding. Make sure that you only feed enough that your current livestock can gobble up in a minute to two minutes. If you don't want to cut back, make sure you have the clean-up crew to compensate for it. Hermit crabs, snails, serpent stars, bottom feeders, etc. If you like protein skimmers and don't want to stop feeding as much, you may look at investing in a higher-rated skimmer. This can be dangerous, though, as some things like nutrient rich waters and if you don't get that balance, they could starve.
Hope this helps some.
