I did some similar curls on my rarity wig and had them hold in place. I used clear drying school glue (PVA glue) to coat part of the hair, just enough that it stuck together. I then wrapped it around toilet paper rolls and held the curls in place with bobby pins. I let it dry for a few days, sprayed it down with hairspray, let that dry and then took off the toilet paper rolls. A bit of the cardboard stuck to the wig but I used warm water to loosen it and remove it.
Result = dem curls (I love this picture lol)
What I like about the above method is that it should work nomatter what your wig is made of, since the glue will hold it in place. But assuming you have tried that method, or some variation of, let’s try to problem solve
- You used the glue method and it didn’t stick
Did you use only hairspray?
Hairspray has it’s limits, it might not be strong enough to hold a curl in place. Try using a clear drying glue instead.
Did you use enough glue to hold the curl in place?
A couple dots won’t hold a full strand in a curl, make sure you are using a fair amount.
Did you hold the curl in place while drying?
If you glue it and then let it do it’s own thing, the curl won’t hold. Whether it be a clip hair curler (not a comb) or bobbypins and a paper tube, you need some sort of structure to hold the curl in place while it dries. Anything cylindrical will do.
Did you allow the curl enough time to dry before removing the curler?
If the glue doesn’t fully dry while being held in position, gravity will work it’s magic and unravel the curl. It may take a full day to dry, let it do it’s thing.
Could you apply heat?
Will your wig take heat ? If so, running the hairdryer to help dry the glue faster and set the curl can help maintain the shape.
Could it just need additional support?
Check the next section.
- You used the tape and wire method and it didn’t hold
Is the tape sticky enough?
If the tape isn’t sticking to the wig you may need to rely on additional glue or caulk to adhere the tape and wire to the wig.
Is the wire strong enough?
If the wig is heavy and the wire is weak, you’re going to have trouble supporting the shape. Try moving up in gauge to remedy the issue. You could also switch to a wire mesh, which will offer more support.
- You used the hot water method
This method isn’t ideal because it works best for more natural curls and doesn’t offer any structural support. I would encourage using the hot water or other heat methods alongside one of the other methods — using heat to set the shape that is supported by glue or wire.
Was the heat high enough?
Different wig fibers can take different temperatures and that might make it hard to curl. I believe Hiperlon can stand the most heat and toyokalon and kanekalon take more heat than regular party wigs. If the heat is too high you might melt the wig, so always test on strands that won’t be missed.
Was the rod used the right diameter?
If the rod that you wrap the fibers around is too small, you’re going to get smaller ringlets than a large curl. This is an issue with the hot water method or using a curling iron.
If this doesn’t pinpoint the problem, try submitting a picture so I can see what is going on. Goodluck!
