The Exposed Track:
Classic (and rookie) weave fail. There should always be enough hair to cover your tracks...just like in life.
If you gotta unkempt weave, I am only to assume you have an unkempt life. Just ask my friend Nay about her roomie Lil. The first time I met Lil, her hair was lookin crazy and she, in turn, ended up being crazy.
The Ridiculous Color:
No one, in the history of the world, was born with blue & purple hair. Now, as a Blonde Bombshell, I think a lil color is fine. I've done a red streak or 2 in my day. But your WHOLE HEAD in purple?? Ummm, nooooo.
Just because you have a weave does not mean you shouldn't wash your hair. Your weave will trap all kinds of smells (sweat, cigarettes, desperation) so make sure you stick to a regular hair care schedule.
