Even the best hair can look poor when it is very dry, so keeping your hair properly moisturized is vital to replenishing it. Dry hair can form as the result of excessive blow-drying, or simply because of the climate in which you live. Most people suffer from dry hair because they style their hair too often, constantly applying hair spray, gel or other chemical products to it. If you can minimize the amount of products you use and the time you spend blow-drying your hair, you should be able to reduce dryness immediately. There are other ways by which you can replenish dry hair, too.
As mentioned above, the easiest way to replenish dry hair is to stop excessive styling and blow-drying. Many people blow-dry their hair because it is quick and effective, but it does do some damage. Other forms of excessive heat, such as hair straighteners, harm hair as well. If you use a hair straightener daily, consider replacing some straightening sessions with a hair relaxer.
Hair relaxers are often made from natural products and "relax" the bond between hair molecules to stop it from curling. Many people believe these products are not as effective as heat-based hair straighteners, but if you simply replace half of your heat-based straightening sessions with the application of a hair relaxer, for example, your hair should still be straight enough for the hair relaxer to be effective.
If you limit the styling of your hair and still suffer from dryness, there are some other steps you can take to improve your hair quality. First, purchase a shampoo and a conditioner that are both formulated to combat dry hair. There are a ton of great products on the market that will not only clean your hair, but also moisturize it in the process. There are even leave-in conditioners which can really attack dry hair and restore its health.
When you do style your hair, properly protecting it beforehand can limit the damage of certain products. Thermal styling spray, for example, can be applied to hair before you work on it to add moisture, limiting the "drying out" effect of hair dryers, straighteners and so on. You can even add this product to wet hair to protect it before you add heat. Thermal styling spray even adds shine to your hair, producing beauty along with improving hair health. Add a small amount of the spray at a time, as applying too much can lead to a build-up of the product and even limit its effectiveness, causing your hair to dry even more.
Lastly, use ceramic styling products. Many new hair dryers are made of ceramic because they produce heat more efficiently, limiting the damage it does on hair. These options are usually more expensive than traditional hair styling products, but it is worth the investment if you suffer from very dry hair.
