I have 4a hair too. I thing cowashing every day is too much. I Cowash 2x on Wed and Sat using Trader Joe Tea Tree Tingle Conditioner and deep condition once or twice a week with Shea Moisture Curl Enhancing Smoothie. Best curl styler for me is Hawaiian Silky Curl Activator. The trick to refresh hair on no Cowash days is to fill a spray bottle with water and spray hair until it is saturated. Do NOT touch hair. Let water saturate hair for a minute or so. As u do, ur curls will start swelling magically. Shake your hair up and down, left and right to loosen them up and voila.
