DO NOT ADD HEAT TO Phillis. INSTRUCTIONS BELOW ARE FOR HEAT RESISTANT UNITS ONLY!
PLEASE BE SURE TO FOLLOW DIRECTIONS ON PACKAGING
Option #1 (Straight to Curly)
-When using a stove iron, heat it to a low warm temperature.
-When using an electric curling iron, set it to low or medium (always start on low)
-Take a section of hair and comb through it.
-Wrap sectioned hair around the iron and hold it for 10-15 seconds.
-For best results, spritz water unto wrapped hair, THEN slowly remove iron from hair, this will allow the hair to cool in shape of curl.
-Repeat above steps until desired style is achieved.
Option #2 (Curly to Straight)
-When using a stove iron, heat it to a low warm temperature.
-When using an electric curling iron, set it to low or medium (always start on low)
-Take a section of hair and comb through it.
-Using the heated iron, slowly move it down the sectioned hair.
-Repeat above steps until desired style is achieved.
Option #3
Mist the hair with a little plain water. Take a small strand of hair between clamp of curling iron and roll around barrel of iron. Keep hair moving around barrel, rolling evenly until all of strand has passed firmly under clamp. Don't rest iron on base of wig as it will create a roller mark. A slight steaming action will not harm fiber.
After curl is formed (not necessarily dry), remove the iron carefully, leaving the curl intact and being careful not to drag the ends out of the curl as this will make the curl uneven. If a looser curl is desired, work the hair with fingers while still warm. If a firmer curl is desired, let dry before combing.
Option #4
Heat rollers or a steam setter (such as a Caruso) may be used on synthetic fiber too. Roll each strand carefully around the roller keeping the ends smooth to reduce "fish-hooking", which makes the ends look fuzzy. Using end papers is recommended. Let the curls get completely cool before brushing or combing out the wig. If using the steam setters, it's a good idea to use a "duckbill" or other similar clip to hold the curls in until they're cool and dry.
BEAUTIFUL
