Hello there!

This answer depends on a few things, such as what you are putting your wig on.

Here’s a few solutions to troubleshoot what the issue is:

If the wig holder itself is stable, but the wig head keeps falling off of it:

You may need to either increase the size of the wig holder or decrease the size of the hole in the bottom of the wig head. A taller or thicker rod for the wig head to sit on would help. You should also check the bottom of the wig head to see the condition of the hole at the bottom: is the wig head old? Has the styrofoam worn away or smooshed down inside and around the edge of the hole? If so, retiring the wig head for display/storage only and getting a new one for styling would help, as this is very common with this type of material, or you can try making the hole smaller again by filling with another material (foam clay might work for that).

If the wig isn’t on a stable base or holder:

This depends on the type of holder you are using. I find that a tripod or otherwise taller holder works quite well (I use a metal stand from a dressform that’s basically a single vertical tube with feet for stability), though tabletop holders are often convenient. If you are using a tabletop holder, make sure it is stable on whatever surface you are using, and consider adding weights to the bottom to help hold it in place. If using a clamp-type holder, make sure that it is securely clamped to the edge of a table or other surface so that it doesn’t wiggle when working. Wiggling is your enemy here.

If the wig head tends to move most with long wigs:

Use the above tips, and also treat longer and heavier wigs with care. Make sure the wig itself is well-secured, and consider placing the long hair on a table or other surface to hold the extra weight when not working on that part of the wig/when you don’t need the hair to be free hanging.

I hope that helps! Good luck :]
