Pour on the conditioner.

Strawlike hair needs conditioning. Look for products that contain little or no alcohol, which will dry out hair even more. Reading labels will help, but it might be simpler just to take a whiff before you buy: Conditioners with little or no fragrance tend to be low in alcohol or contain none at all. If your hair is really dry, consider using an overnight conditioner, which you apply before going to bed (you sleep wearing a shower cap) and rinse off in the morning.
