The WGO is good. I have been using it since October 2002 and love it. I have the same bottle too, so a little does go very far. This past wash, I am at 4 weeks post-relaxer and usually have a hard time with new growth. But after I washed and conditioned, I applied a good amount of WGO to both my roots and hair after I saturated with setting lotion.
The effect was great and this is the second time I have done this. My set came out really soft and so is my new growth. But just to be on the safe side, once your new growth gets noticeable, avoid wrapping to cut down on the shedding.
Hope this helps
