I am also using Robin's techniques for the care of my braids. I also have a tea of amla, bhringraj and brahmi powders and a few drops of essential oil that I use as a rinse that I spray on my scalp and roots for strengthening purposes. This is an added tip I got from Sareca.
I only wash my braids every 2 weeks though because for me, every week is too much manipulation and I really don't want my hair to matt up. I re-do my edges every 4 weeks and remove braids every 8 weeks and have them re-done 2 weeks later. NB: Your edges should be re-done every 2 to 3 weeks.
