Is it healthy?

Is it weighted down by 'stuff' (gel, spray, mousse. leftover shampoo/conditioner, smog...etc.)

Is it dry or soft? Using a hair dryer or hot rollers on it will tend to umm train it not to try and do it's own thing, and hair generally likes to head away from each other as its own thing, which means flyaway or body, depending on health and genetics. also all those things and products dry out hair, which makes most pile on stuff to make it shiny/not flyaway....meaning pulled flat...meaning you head for more 'stuff'..bad cycle.

Have you tried brushing it/washing it upside down...sounds odd, but it tends to add body.

Also combing lines up the hairs and lays them flat....after you get the knots out if you want body, ditch the comb and use your fingers, bigger spaces between hairs, and you can loosen up the top most hairs to add even more air pockets without too much trouble....though it takes time..haven't put that much time into my hair since I got married.
Teasing will damage the hair in the long run, actually it damages in the short run too, but my point is no style is worth damage IMO. (would you scrape up your skin to fit in? nope, so why do it to your hair?

Any cut that will encourage body will also grow funny and mean maintenance cuts...not that you can't, just that lazy ole me sticks with straight across...
