Taking proper care of your synthetic wig is not always intuitive because you cannot always apply the same rules you would follow with your natural hair. One situation in which synthetic wigs need special care is when the ends become dry. This can occur as a result of brushing, styling and heavy wear. Dry, damaged and frizzy ends show a wig's age and can make the wig appear poor in quality. Correcting this issue will improve the look and longevity of your wig.

Trim the ends of the wig. This is the easiest way to get rid of dry ends. After trimming or cutting the wig, you can style it into a new, shorter shape. However, unlike real hair, the ends will never grow back, so you can only do this a few times.

Apply a heavy-duty moisturizing or leave-in conditioning product, the heavier the better. Since synthetic hair cannot actually absorb the moisture, you want something that will seal and separate the ends while adding sheen. Look for a lotion or cream with conditioning ingredients such as jojoba oil, shea butter or peanut extract. An oil sheen sprayed on the ends can also add much-needed moisture and shine.

Detangle the ends. Tangles can make the ends of your wig look dry and frizzy. Use your fingers or a wide-tooth comb to very gently work through the tangles at the ends of the wig. You may have to apply a detangling lotion if the tangles are very difficult to remove. Do not use a fine-tooth comb, as this can increase the frayed appearance of the wig.

If your wig is heat-friendly, use a heat styling tool after applying your product. Most synthetic wigs will burn or melt when they come into contact with heat. However, some synthetic wigs are specially developed to withstand heat. You can use a curling iron or flat iron to smooth the dry ends and improve the frayed look. Use the lowest setting to start, and slowly increase the temperature, constantly checking the wig to make sure it isn’t getting damaged.
