is your weave straight or curly? when i had a weave it was a kinky/curly weave and it appreciated all the moisture it could get, so i didnt mind washing/cowashing weekly, but after about a month my braids underneath and the tracks started loosening from all the water, and i cut back to every 2 weeks, but i would still moisturize my braids & the weave with water/condish/oil/AVJ in a spray bottle almost every day...i detangled with a paddle brush or my fingers mostly...at first at night i would put it in twists, but i found my hair looked better and shed less when i just pinappled and slept on a satin pillowcase...i think straight weave maintenance is harder, especially if you're natural and you have to worry about blending, plus you dont want the hair to get wet and revert or get poofy because then you have to straighten it again and all that
