When asking for 'texturizing' at the salon, I usually end up with something that is too 'softly' textured. I know there are different types of texturizing shears. How do I get a stylist to make the texture 'chunky'? I am usually never satisfied with the texture. Is this something I could do at home? If so, how many 'teeth' should be in the scissors? I have a lot of hair and it is short. Thank you.
