Red I donīt think so. The whole Hair thing is like this: it seems to be important to you, to be a represantation of your personality (which of course is also held up by the way you write here and many other things). Still you give in to your daddy... I think giving in concerning things that are important for you, going through changes that are hard for you is sure enough submissive. that you do it even if itīs not easy... you may well show how hard it is..
Things you donīt care for could easily be changed if it pleased him but were in themself not as strong a sign of your submission... so if itīs perhaps as unimportant to him as it is to you - why should he ask for it??
...just my thinking...
just the same about you beeing able to think for yourself.. where lay the submission in a person not able to decide for him/herself if he/she left all decisions to her partner? it would be pure necessity. Whereas a person totally able to care/think/live for him/herself who conciously decides to hand over certain rights , for example the right to decide the haircolor, would for me certainly be submissive, wether or not she struggles with her own decicions from time to time.
..keep it goin ;-)
