I'm sure Jedis should be able to burn little kids hair with their light sabres. If a kid needed a little trim up top, why couldn't a Jedi just burn a bit off for him? Jedis are supposed to be protectors of good and what not. It seems illogical to me that a Jedi can't go handing out free haircuts to kids under the age of eight.
The real question is: Why am I dreaming about buying Star Wars toys in Woolworths and then becoming a Jedi apprentice?
The answer? I simply don't know. But I had two light sabres, and I could hand out haircuts and bully little kids like it was the dark ages.
Really, I think all of us have an inner desire to cut hair. Whether or not we do it with a light sabre depends on technological advancements in the next ten years or so. Until then, we'll just have to settle for scissors - and if it's hot enough outside - we could focus a beam of light from the sun through a magnifying glass and burn away individual strands.
This however is a slow and and mediocre way to burn little kids hair, and if a kid is pissing you off you can't really stop and ask him (or her) to stop and wait there while you while you redirect the intense energy of the sun. No much better to use a light sabre, and as I've mentioned earlier - that is neither here nor there.
If some momentous event occurred that allowed us to all carry light sabres, we could all start our own barber shops. Competition would be fierce, and we could all retire at lunch and watch the antics of two cats tied together at the head with sticks. The cats would also have had haircuts with light sabres, but these types of trims would require much finer control and would generally only be performed by a master. Eventually all the Jedi masters could ride their penny farthing bikes to the town square, with a kitten in their pocket. All the masters would gather in the town square and show off their fine hair cutting skills, making the kittens into little works of hair cutting art - much like Johnny Depp sculpts bushes in Edward Scissorhands.
Life would be much more exciting - "Give me a little off the top and neaten up the back and sides" would not be the same tired boring process it is now. A Jedi barber could ignite his weapon, spin and execute a high strike, neatening the top off in one clean strike. Likewise, one stroke up or down - depending on preference are all that would be required for the back and sides. hair cuts would be better and faster.

The next question to be asked is whether or not there will be a Jedi council for the barbers, and if there would be a great Jedi barber academy - filled with great libraries and training rooms for cutting hair. I envision a great hall, with dorrs all around the walls. A lone Jedi in the middle. Suddenly, all the doors open, and out springs forth little kids, kittens, old men and yuppies - all crying "How much to have this done?" From above there would be nothing but flashes of light, and a low humming would be heard, interspersed with an occasional high screech as sparks were emitted. At the end, all would have had their hair trimmed, and the Jedi would ask no more than a penny for his troubles. This penny would not be profit however - the Jedi would use this penny to pay for a small hairless child from Madagascar to come and sweep the arena floor.
There are too many slow and tedious ways to burn hair - particurlarly the hair on little kids heads. If all goes well we will see advancement in this area soon.
