A person who styles and cuts hair is called a hairstylist or a hairdresser. They are trained in various techniques for cutting, coloring, and styling hair to enhance their clients' appearance. Some may also offer additional services such as hair treatments and extensions.
Some popular styles for a size 4 haircut include pixie cuts, bob cuts, layered cuts, and asymmetrical cuts. These styles can be customized to suit individual preferences and hair textures.
The best place to get a catalog of current hair styles and hair cuts is at your local hair dresser. They will have multiple magazines lying around which will be able to help you choose your next hairstyle.
There are many magazines and websites that offer ideas for those who have long layered hair. Try targeting celebrities since they often create styles that change their look. Cosmopolitan is a magazine where ideas can be found. A web search for layered hair cuts is a good way to also find ideas.
Someone who cuts their own hair is often referred to as a "DIY hairstylist" or simply a "self-haircutter." This practice can also be described as "home haircutting." People may choose to cut their own hair for convenience, cost savings, or personal preference.
