How to make a bald cap - SFX theatrical

How to make a bald cap - SFX theatrical
Bald caps are used in a variety of theatrical situations, not least to make someone look bald!

They are also often used as the basis for other make up SFX effects and for headpieces, or to cover up the hair when making face and head life casts.

Bald caps are easy to make, and the materials aren't too difficult to assemble. You will need:

Liquid Latex
A polystyrene, glass or fibreglass head (used for hat displays and similar).
Some cheap bath sponges
DVD marker pens
PVA Glue (if using a polystyrene head).
Talcum powder.

Without doubt the most important, and possibly most difficult to acquire is the head. Glass ones are the best but they are expensive. Mannequin fibreglass ones can sometimes be found at car boot sales or bankrupt stock, but you can use a polystyrene one perfectly well. These are cheap and readily available on the net. I got my mannequin head for nothing from a closing down sale, and the polystyrene one cost me a fiver with postage.

Step 1Preparing your head

Preparing your head
One thing you will notice when getting a head is the large variety of cranium sizes! Below are my mannequin head and my styrene one, note the difference. Latex is very elastic (they make condoms out of it) so you could just use the smallest one and have done with it. However if your model has a big head or a lot of hair, and has to wear the cap for any length of time it makes sense to try and get a reasonable fit to start with.

If you can only get a polystyrene head then you should consider preparing it for use. You can make bald caps using the head as is, but eventually the soft surface of the head will start to break down and lumps will get pulled out of it.

You need to give it A LOT of coats of PVA glue to seal and strengthen it. I took 3 weeks and 25 thin coats of PVA, allowing each one to dry in between. This gives a really tough and non-porous 'skin' to the head so I can use it for all sorts of work. Obviously it won't take heat or serious chemicals which will both melt it.

Once you have a sealed head it is advisable to mark it. This will allow for good feathered edges to your bald cap. Decide if you want an all over cap (which must be cut back), or if you are happy that the ears can be left out.

Mark the head using the DVD pens (I use different colours for each edge) such that the first line covers the entire area of the cap, the second is about 1/4" (six millimetres) inside the first, the third is 1/4" inside that and the fourth 1/4" inside that. See the picture for a visual guide.

Your head is now ready.

Hi, how many layers do you need to make the latex strong for the cap? Also, whats the best way of peeling these off? I have a polystyrene head. I havnt coated it with anything at the moment tho.. currently making one, and have about 5 layers.
Thanks

awesome instructable :D is there any way of re-using a bald cap or is it a "just one use then throw it away" kind of thing?

In theater, we use heads a lot to make head shaped things. We put on a layer of ORIGINAL saran wrap and hit it with a steamer to shrink wrap it to the head. It does make wrinkles, but you might be able to keep them to a minimum and in places not so critical to the look. I don't know if the plastic will stick to the PVA but maybe treating it with a mold release agent might work. Maybe a real light coat of WD40. Just not so much that you cant get down a coat of the latex.

 Is that person on the front wearing one, because I sure can't tell...!

To answer your question: Yes. And I'll use the example given on the front page to explain.  You see, the picture of Cameron Diaz comes from the movie "My Sister's Keeper," which called for her character to shave her head.  Now, as many people know, movies are shot out of sequence.  Sometimes, actors who are truly dedicated to the movie would be willing to shave their heads for the role if its required.  Sometimes, some of them may refuse to shave their heads, resulting in the use of a bald cap.  Since one of Ms. Diaz's trademark features happens to be her golden blond hair, she wouldn't risk shaving it.  And the best makeup artists make something like a bald cap look so natural, you wouldn't be able to tell.

u can also tell becuz if a person shaves their head (and i know from repeated experience) they won't be completely bald but rather have short bristles. A person who is bald and has no bristles would be balding naturaly (or wearing a bald cap) and not shaved.
