Final answer:
To stretch a cap wig properly, lightly spray it with water or wig conditioner before manipulating it, ensuring the right level of moisture for pliability without causing damage.
Step-by-step explanation:
Before stretching a cap wig, it's important to moisten the cap to make it more pliable and easier to manipulate. This is usually done by lightly spraying the cap with water or a specialized wig conditioner. The moisture helps to prevent the fibers in the cap from breaking and allows the cap to be stretched effectively over a wig block or a client's head without causing damage. It's essential to use the correct amount of moisture; too much can overly saturate and potentially damage the cap, while too little might not provide the necessary flexibility.
