Hair: All natural dark brown and silver.
Washing: Twice a week, scalp wash, with letting shampoo run through length. Condition from ears on down. Cold as I can stand it final rinse.
Shampoo/Conditioner: I have switched to organic. Aubrey's Honeysuckle Rose Shampoo and Conditioner. Nature's Gate Organics Biotin Shampoo and Conditioner.
Comb, never brush.
