I surged quite often (a few times a week) and MTG'd once every 3 or 4 weeks. Actually, I would MTG my hair late at night, wrap a towel around my hair and then wash my hair the next day. That MTG really gets into the extension and the smell is hard to go away. But in the end, I took the braids out and there was still alot of build up around the knot of the hair, so I don't know if I should have done it or not. I think its safer to Surge often and then if you do MTG, put the MTG on your finger and then rub that into your scalp. I took half of my braids out last night, and the rest I will take out in a week or two. Then I will prolly let my hair rest for a few weeks, and put them back in again.
