Ways To Care Bob Wigs
Comb it out after wearing and before you wear it.
Keep it's hair net on it when you're storing it if at all possible. If it is a bob wig, carefully curl up the long tail and tuck it inside the hair net in a gentle curve. Don't twist it too tight or you'll accidentally style your wig.
First, throw out the brush. Get a wide wire toothed comb.
Comb out the tangles before you wash it, else you will matt it more before it gets better.
If the bob wigs are really bad, use a spray detangler.
Take the conditioned wig to a table or TV tray and put in a good movie. Oh, and bring a tiny pair of snips, preferably with a point and some hair clips.
Just take one section at a time and carefully use the clips to get the rest of the hair out of the way. Lay the section against the flat table top. Comb goes in your main hand, other hand holds the wig fibers flat to the table. If you need to pick it up to check out a knot, hold the fibers between your thumb and forefinger.
Just comb the bottom inch first. Don't pull. Work it with your fingers if you have to. Soft strokes...like petting a cat. Hold the fibers yourself. Get that inch detangled. You should be able to. Sometimes you will be separating out a stand or two at a time.
If you absolutely possibility cannot get a knot out... get it down to as few of hairs as possible. Then pick up the snips, or cuticle scissors and try to cut just a hair or two. Often that's enough to get the knot out.
Once you have the bottom inch combed, move up and comb out the next inch so now you're combing two inches. Don't worry if some of the curl is
Keep adding an inch at a time, don't get impatient, you'll find that you comb the knots down lower. If it is a really bad area, like the back you may have to start back at that last inch again. However, it will go faster this time.
Once you have the whole section done, pin it up carefully and move to another section... start from scratch.
When all of the sections are done...unclip. Put on bob cut wigs head, carefully comb though it again. Now you're blending the sections back together. You'll still hit some tangles.
Now start looking at what it takes to put the style back. You may just need to pull some curls out and wrap them around your finger for a moment, or it may take a new set.
What you do next time, wearing a wig is like taking care of any part of the costume. Consider combing it out after wearing like cleaning the glue off your ears.
