The thread you've referred is helping much (lemme read it full first).... Butttttt even if HE is helping, he can only help in taking out the pins... rest I have the remove all that tangles myself... I can do it, but couldnt if someone is waiting out!
The best thing is to untangle with a ballpoint pen. yes a ball point pen. It takes a long time but I have trie dit after being told by a salon owner and it worked. Better to tell teh hair stylist though not to do a lot of back combing and not use lots of hair spray. Good luck.
