To make your hair less dry and frizzy, try using a deep conditioning hair mask at least once a week. You can also try using a leave-in conditioner with natural oils as a daily moisturizer. Additionally, try using a wide-toothed comb to brush your hair instead of a brush, and avoid using hot styling tools such as curling irons and blow dryers. Lastly, try cutting back on washing your hair too often, as this can strip the natural oils from your hair.
