I think you'd have to wait 2-4 mo. after you do your big chop, RushGirl. After I BC'd I had this awful haystack on my head!! I thought, "OMG!!!" Eventually, that all came out, leaving me with softer hair that was able to absorb moisturizer. Before, that haystack wasn't absorbing nothing!!! I could put a ton of moisturizer on it and my hair would mock me bitterly. /images/graemlins/frown.gif
You can't do nothing with scab hair. It'll just sit there looking at you like, "So, you wanna piece of me??" /images/graemlins/rofl.gif
And yes, some areas can be more 'scabby' than others.
