Looking after synthetic hair extensions can be a bit of a pain, as extensions are much more difficult to care for long-term than head-grown long hair. With nice care and attention, however, it is possible to keep synthetic extensions looking perfect for as long as possible.
Steps
1. Check the quality level of the synthetic hair you have. The cheapest synthetic hair cannot have heat (flat irons, curling irons, or hot rollers) used on it as this will most likely melt the synthetic fibers. There's, however, some kinds of synthetic fiber (e.g., Monofiber, Thermofiber) that can withstand heat to a sure degree. If the ability to use heated styling tools to the extensions is a necessity for you, check out this possibility before you buy.
2. Use detangling spray on the extensions every day. Always comb this through . This product should stop the hair tangling together and stop it getting frizzy. In addition, use an appropriate comb or brush designed for use with extensions; normal combs and brushes can destroy the wefts and cause the extensions to loosen or pull out.
3. Wash out any hairspray or other styling products at the finish of the day with a mild shampoo and conditioner. Use chilled water. Invest in some shampoo designed for synthetic wigs. They are made of the same kind of fibers and this will help stop your extensions from tangling.
4. Trim frizzy ends, and then rub some oil onto your extensions and comb it through. Leave it for an hour, and then wipe off excess oil out of the hair using as towel. Wash with a mild shampoo and rinse.
5. Make a decision to renew or remove the hair extensions well before they look ratty. Hair extensions tend to move up the hair shaft at around the five week point, making them liable to loosen or become uneven. If this is your first time wearing them, you might pick that the work involved in caring for them is not worth keeping them again; or, it might be something you are willing to keep with for a time longer. Either way, a return to the hairdresser to get them sorted is essential at this point.
6. Curl the extensions carefully. Most synthetic extensions are straight, and will stay straight, even after washing. However if you need curls, get some hair-curlers (the ones you roll in to your hair). Heat some water until it is very warm (not boiling) and dip your extensions in (if they are not clip-in extensions, put hot water in a spritz bottle and spritz your hair over) and then roll the curlers in to the hair. Leave to dry naturally, and remove when the hair is dried. Your extensions should now be curly.
