i think it varies from person to person, depending on your hair and how often you would be blowdrying. if i blow dry more than once per month, i am not able to retain more length. frequent blowdrying (for me), leads to more split ends and dryer hair which in turn leads to more trimming/cutting of my hair. its taken me forever to realize that i just can't get away with blowdrying too much, no matter what heat protectant i use.
i haven't put down the blowdryer all together though, but i try not to use more than once per month. also, i'm currently about an inch below brastrap.
^^^^^this is basically me too. i am apl though...sorry didn't read the op
except i only blow dry with touch ups now. heat keeps me from retaining
