Frizzy thick hair sometimes requires additional care than other hair types, to make sure it is soft, healthy, and able to be styled. From the way you wash it to the methods you use to style and dry, these can all differ with frizzy thick hair. In addition, people with frizzy hair frequently have dry hair as well, which also requires extra care. In general, cutting down on the amount of washings with shampoo per week, as well as the amount of heat styling, can be a good way to treat this hair type. Using a moisturizing conditioner is important as well.
Many people find that one of the best ways to care for their frizzy thick hair is to reduce the amount of times they wash it. Shampoo can strip hair of its natural oils, which can contribute to dryness and frizz. Therefore, washing hair every other day, or even every few days, can help it to look smoother, and retain more of its natural moisture. Of course, this is only an option for people who do not have a naturally greasy or oily scalp; for many people, there is no other option, but to wash the hair every day.
If you have frizzy thick hair, and it is necessary for you to wash your hair every day, using slightly cooler water rather than scalding hot can be a good choice, as well as a moisturizing shampoo and conditioner. A leave-in conditioner that is applied after getting out of the shower can help start combating frizz right away; other products that are intended to smooth the hair or protect it from heat styling tools such as straighteners, curling irons, or blow dryers. Be judicious with products, though; some things, such as hair spray, can actually dry out the hair even more.
Drying and styling frizzy thick hair is another consideration. Using a blow dryer on a low heat setting, making sure to aim it down the hair shaft from the scalp to the ends, and finishing with a blast of cool air can help to smooth and style frizzy thick hair. Most people find that letting this type of hair air-dry is nearly impossible, because it increases in frizz throughout the day. Pinning it up and letting it dry is one way to control frizz and avoid using heat styling, which can contribute to dryness as well. You may need to do some trial and error to find the method that works best for you and your type of hair.
