I have a huge TANGLED KNOT in the middle of my hair. It's a results of braiding, cowashing a few times and not having time to detangle between cowashes. I have just washed my hair and deep conditioned with Keracare Humecto, and attempted detangling for the past hour in the shower and it won't budge... any suggestions? I would hate to have to cut a huge chunk of my hair off, I get married in 4 months. Any suggestions? mayo, olive oil? anything? PLEASE HELP...
