Many different things, from working in the food industry to wearing a wig, will require wearing a hair net. The proper way is always the same and provides the most comfort for whomever is wearing the hair net. There are slightly different methods to use, depending on whether your hair is short or long, and it may take a little practice to get it right.
If you have short hair, use a pomade or styling cream on hair. Work it through from root to tip to create a slick hair surface. Use a comb to pull all hair back and secure down any stray ends with a bobby pin. These can be place haphazardly throughout the hair as they will be covered with the hair net. If your hair has a tendency to fall out of place, use hairspray after pinning your hair down. Open the hair net and place it on your head, starting at the forehead, carefully stretching it back and tucking it on the sides of your head and at the nape of the neck. Make sure there are no stray hairs sticking out and avoid stretching the hair net too wide, which can make it slip off your head.
Pull long hair back into into a tight ponytail at the nape of the neck or at the center of the back of your head. Both work, so do whichever is most comfortable. Use styling cream or gel to slick your hair back to be sure every hair is in place. Secure the ponytail with a hair elastic and work additional product through the "tail" of the ponytail. Twist the ponytail and coil it around the base of the ponytail and secure it with bobby pins. Use a fine-tooth comb to smooth any stray hairs, especially at the nape of the neck. Stretch the hair net, starting at the front of the head and bring it over the sides of the head, taking in the nape of the neck last.
Get the Hair Net Perfect
The idea of wearing a hair net is to keep hair from leaving the head. For this reason, be sure you bring the hair net all the way over the hairline, whether it's around the face or back at the neck. You don't want a stray hair to escape, and if it does, it's best if it falls inside the hair net.
