Wear a scarf, hat or cap to protect your hair from the sun but make sure that it’s not so tight that it will restrict circulation in your scalp.
If you know you are going to be in the sun for a long time and if you don’t want to wear anything on your head, use a leave in conditioner with sunscreen in it before you go out.
If you are outside and forgot to put leave in conditioner with sunscreen in your hair, you can put regular sunscreen in your hair, but make sure you rinse it out with a deep cleansing shampoo when you get home.
Limit your use of “hot” items on your hair such as a blow dryers and curling irons.
If you need to use a “hot” item, use a leave in conditioner before using the item on your hair.
Avoid taking hot showers or washing your hair in hot water, use warm or cool water instead, the heat can dry out and/or damage your hair and skin.

Avoid hair products with formaldehyde or alcohol in it which dry out hair, try to use natural products that are gentler on your hair.
Try washing your hair less often; shampooing your hair strips the moisture out of your hair.
