Understanding Your Hair Structure and Composition

What is hair made of? In order to best support your hair, it’s helpful to understand its detailed structure and composition. Just like your skin, your hair has multiple facets that need attention.

At Prose, we believe it’s valuable to understand the science underlying your hair in order to properly care for it. It’s our main mission to bring products to you through in-depth research. We are able to provide natural ingredients because we are constantly researching and sourcing the best ones for your hair. That’s why we’re here to explain what hair is, how it grows, how to look after it, and more.

    Hair anatomy

    Learning about your hair could mean understanding what it is made up of, or how your hair stands alone with no product or styling. If you begin to look at the anatomy of hair, you could learn that fibrous protein makes up the majority of hair (65-95%, to be exact). 

    This important protein is keratin. Here are some quick facts about keratin:

    Wondering what hair structure is? Here are three key parts of your hair:


    The hair follicle, which is found beneath the skin, and the hair shaft, which is visible, are two distinct components that make up your hair. We’ve touched on what makes up your hair, but, you may be wondering, how does hair keep growing? Here are the three phases of hair development:


    Hair grows at various rates for different people; the average monthly growth rate is around a half-inch. Some have slower hair growth, while others’ hair grows rapidly. 

    Pigment cells in the hair follicle produce melanin, which gives hair its color. Pigment cells die as we age, and our hair begins to gray. Your hair can go through numerous changes throughout your life, and can even change week by week. Your hair structure and composition stand out, and we make products that help set your hair apart.

    Some curly, some straight

    You may be wondering why some people have straighter hair, and others have curly hair. Many of us know that we could get our hair shape and texture from our genetics, but how is it that some hair grows one way and others grow differently? 

    Taking a closer look at hair patterns can help you identify the differences in your hair growth. The form of the follicle plays a role in deciding whether your hair is curly or straight. Hair will grow straight if the follicle is round, wavy if the follicle is oval, and curly if the follicle is hooked or elliptical.

    Looking closer at your hair type

    Your hair may be straight, wavy, or curly. Your specific hair could also feel like it falls outside these categories, or it could fall within multiple. And your hair, just like your skin, may display a variety of characteristics. Identifying your hair type is a great way to understand its structure and composition. 

    After taking time to look into and identify your hair type, you can start to understand which products are best for styling your hair.

    Type one

    If your hair is straight or fine, you may want to look for volumizing products to give your hair a boost. Dry shampoo can also give your hair more texture and body.

    Type two

    If your hair is wavy, look into styling creams or hair oils. Using these products could help smooth away unwanted frizz for a more controlled texture. You can also use a wave or curl spray to intensify the natural movement in your hair.

    Type three

    If your hair is curly, go for products that provide moisture. We recommend trying our leave-in conditioner, hair oil, or curl cream to help keep your curls bouncy and moisturized. With curly hair, you may not want to brush your curls out, but instead, use a wide-tooth comb. Or, you could also run your fingers through your curls as a brushing method.

    Type four

    Lastly, if your hair has much tighter curls, similar information for type three hair applies. You’ll want to use products that keep your hair full of moisture. Butters, oils, curl creams, and thick leave-in conditioners can help seal in moisture. We help by providing ingredients that can give more moisture and bounce to your hair. 

    These hair tips are all suggestions, as there are so many types of hair. There are also subcategories to each hair type. You can start by looking at your unique hair, and choosing the hair texture that is most abundant throughout your strands. 

    The hair type chart can be a good place to start. You may have parts of your hair that are wavy and parts that are straight. Hair structure and composition can look vastly different for each person. 

    Your hair is unique to you, and here at Prose, we are in the business of supplying the most personalized products for your individual hair journey so you can achieve your personal hair goals for your specific hair. 

    Your hair structure may not feel simple to you, but we help by simplifying your hair care. Knowing your hair type can help you determine your hair needs, and our products go the extra mile to take care of your hair.
