Before washing, detangle gently from the ends upward. Use a comfortable amount of shampoo and focus it on the scalp, where product and oil tend to collect. Let the rinse carry it through the lengths.
Apply conditioner where your hair needs it most, often through the mid-lengths and ends. A small amount of hair oil can help smooth dry ends, but start with less than you think you need.
Hair needs vary from person to person. Adjust how often you wash and which products you use according to your scalp, texture, and routine.
