I do daily co washes, too, especially since I have been working out daily more recently. I have had great success with them. I also have experienced no shedding and softer, shinier, bouncier hair. I am really quite surprised. Some of the co.'s I use are Aubrey's GPB, Frederick Fekkai Protein Rx, Keracare Humecto, and a leave-in by Alba Botanica after along with jojoba oil. On the ends, I use Phytospecific Moisturizing styling balm (done after pony is formed). It is working for me. I also do the air-dry pony, which I learned from this forum.
I lightly blowdry on cool (no heat) after applying products (and gently combing thru, then putting hair in pony) and airdry the rest of the night. I am loving this so far. I haven't fought with my hair since I started doing this. Before I did, my hair was shedding so much, I kept a swiffer in the bathroom just to pick it all up after every comb-out. This is really working for me!
Also, the elasticity of my hair has greatly improved. My hair is stronger and doesn't easily snap when pulled between my fingers. Used to snap like dry grass. Did I say that I was loving this, already?
I am 4a/b relaxed. I shampoo once a week and use Frederick Fekkai Apple Cider Clearing Rinse as needed. Sorry so long!
