hurrrrr,
have you tried garnier fructis volume spray?
my mom wanted to make my hair really big and poofy for my formal dance so she made me bend over and then she sprayed my hair while i was bent over then when i stood back up i looked like a mad scientist. we had to flatten it with a comb and it still looked poofy (but nice eventually). and my hair stayed like that for the rest of the night. it works really well.
this is what it looks like.
also i use redken rough paste to seperate my layers. it makes them looks choppy (and it adds a little volume).
heeeeere it is.
i also use this lovely gel in my hair when it's wet. it works wonders.
ooooh such lovely gel!
/that's just what i use. you should looks further into fructis products. they're really great (i also use their volumizing shampoo and conditioner).
