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.
Good but not great
