I'm currently wearing my hair in jumbo twists. I'm going to take one twist out and look at/ feel my hair later today. Depending on the results (i.e. if my hair feels greasy) then I'll either pre-poo again this weekend or do this every 2 to 4 weeks. Because I clay wash I wouldn't be able to managing having "too much" oil in my hair, but I don't want to give up the ease this provided me in removing shed hair. How often are you using this method?
