Try applying baby oil, or any oil, on your scalp using a cotton ball right before you wash your hair. This will help dissolve the flakes and soften the scap.
Don't scratch your scalp at all...and this includes w/ a comb. Leave head and shoulders on for at least 3 min, prefferably more, and if you can wash w/ baby shampoo after. This is my routine and it's helped tremendously.
