1C Hair Type Guide – Achieve Healthy Hair Effortlessly!

If you ask many people what their hair type is, they will mostly describe their curl pattern, curly, wavy, or straight. Others will say that their hair type is thick or coarse, while others will describe theirs as thin.

Still, other people will express themselves or have other people describe them as blonde-haired women or men, black-haired, or a colored-hair person. While all these hair descriptions are correct, they do not give the specific hair type.

There are about twelve hair types grouped into four main categories that are more specific. The specifics include hair texture, amount of curls, and hair strand thickness. Each of the four categories has subcategories that give detailed information about different hair types, including hair strand thickness, amount of curls, and texture.

What Are The Four Main Hair Categories?

Picking one’s exact hair type is not easy, especially for people whose hair displays characteristics of more than one type. Both men and women have four main hair categories: 1, 2, 3, and 4.

  • Hair type 1 is straight hair
  • Type 2 is wavy hair
  • Type 3 is curly hair
  • Type 4 is kinky hair

Each of the four hair types has three subcategories grouped as A, B, and C. For example, straight hair type 1 has three subcategories of type 1A, type 1B, and type 1C. The same goes for all the other main hair type categories. In our article today, we focus on 1C hair type.

What Is 1C Hair Type?

IC Hair type

Unlike other hair types, Type 1 hair stays straight irrespective of how often you try to curl it. It is also flat from the roots to the hair tips. Moreover, it has a soft, thin, and silky texture with a shiny and delicate look.

Due to its fine and soft texture, type 1 hair secretes high sebum levels, making it oily, which is also one of its significant downsides.

One of the most common subcategories of type 1 straight hair is type 1C hair. The other two are type 1a and 1b. Of the three types 1 hair, type 1C has the softest bends and most body.

Additionally, it is also the only type 1 hair most likely to hold its curls. The hair type texture is loose and prone to tangles, frizz, dryness, oiliness, and limp locks.

Even though it has the oily characteristics of all type 1 hair categories, it has the slightest shine compared to the other two type 1-hair types. The ability to hold curls better than the other two subcategories is due to their thick and coarse texture.

How to Determine Your Hair Type-Women

Determining your hair type is not easy, but it is necessary. Hair, just like your skin, needs effective care with the right products for healthy growth. If you do not know your hair type, you will most likely use the wrong products for your daily hair care routine, leading to poor quality and unhealthy hair.

The most obvious way of determining your hair type is by checking if you fall under the wavy, curly, straight, or kinky categories. However, the following factors also play a significant role in determining your unique and specific hair type.


Determining the density of your hair is one way of categorizing your hair type. The number of hair strands on a square per inch of your scalp determines the density of your hair. Hair density varies from one person to the next and from one ethnicity to the next. A mature, healthy adult typically has between 80,000 and 120,000 hair strands.

Even though hair density is not an indication of a person’s overall health, nutrition deficiencies can reduce hair density. Age is also another factor that affects the overall density of the hair. Younger people between the ages of 20 and 30 have higher hair densities than those at the age of 50 and above.

Counting the hair strands one by one may seem impractical and tedious to most people. Instead of counting, you can determine the hair density by inspecting your money with the help of a mirror. Your hair density is low if your scalp is visible without parting the hair. If you need to part the hair slightly to see the scalp, you have medium hair density. Lastly, if you do not see your scalp easily after parting the hair, you have high hair density.


hair structure

Checking the structure of your hair is another way to determine your hair type. The method is very similar to checking your hair‘s density, but in this one, you specifically stick to the strands’ thickness instead of the number. Strand thickness affects how your hair reacts to specific products and how it holds different styles.

Hair thickness can be fine, medium, or coarse. The easiest way to determine the thickness is by lifting a single hair strand from your hairbrush, laying it on a flat or plane surface, and comparing it to a piece of thin sewing thread. You have fine hair if it is thinner than the sewing thread.

If it is thicker, you have a coarse or thick hair structure. If it is in between thick and thin, then your hair structure is medium.

Furthermore, how your hair holds a style also determines its structure. The hair structure that maintains shape and style for long is coarse hair. Fine hair is too delicate to keep curls in place, while medium hairstyles easily and hold styles for a little longer than fine hair.


Hair porosity is less of a hair type determinant compared to density, texture, and structure. However, knowing your hair porosity helps you to choose the appropriate products for your hair.

The easiest method of checking your hair porosity is by placing a single strand into a bowl with water. If the strand of hair stays below the water surface but does not reach the bottom of the bowl, your hair porosity is normal or well balanced.

If the strand sinks to the bottom of the bowl, your hair porosity is high. High porosity is also an indication that your hair absorbs lots of moisture. Your hair has low porosity if the strand of hair floats above the water surface. Low porosity is an indication that your hair absorbs moisture slowly, which is also an indication of low moisture absorption.

High porosity hair tends to become brittle and dry due to tears and gaps on the cuticles that absorb moisture too fast. If you have high porosity hair, you should avoid harsh chemicals and heat styling because they dry the hair even more.

Instead, you should use nourishing products that provide your hair and scalp with more moisture to seal the tears and gaps and prevent further damage.

On the other hand, hair types with low porosity have flat, laid cuticles that prevent the strands from absorbing water or moisture. The biggest concern for low porosity hair types is product buildup on the hair shaft. The best way to maintain healthy hair is by applying hair products when the hair is damp for better distribution and absorption.


Your hair strandstexture or natural shape is one of the best ways to determine your hair type. You can run a hair texture test to find out which of the four categories you belong to by simply washing your hair and leaving it to air dry without using heat or any chemicals. If, after drying your hair, it does not have a bend or any curls but is straight, then you have type 1 hair.

If you notice an S shape after it dries, you have hair type 2. If you see a curly look or a loop pattern, you have hair type 3. Lastly, if, after drying, your hair has zigzag patterns, spirals, coils, or tight curls, you have hair type 4.

Status of the Scalp

Checking the condition of your scalp also helps to determine your hair type. It goes without saying that if you have issues with your scalp, then most likely, your hair will also be in bad shape. Your scalp can be either oily or dry.

If, after washing your hair, you notice greasy and flat roots; your sebum production is high leading to an oily scalp. If you do not correct this issue, you will end up with buildup on your scalp and hair strands.

If, after washing, you notice flaking and split ends, you have a dry scalp, which is an indication of a lack of natural oils. In this case, you will need hydrating products with no harsh chemicals such as parabens or sulfates. If, after washing, you notice that your scalp is both flaky and oily, you have a combination scalp brought about by oil buildup, improper hair care, and use of inappropriate hair products.

In such a case, you will need soothing scalp products with formulas that reduce oil secretion and prevent buildups.

How to Determine Your Hair Type-Men

men hair type


Men, too, just like women, have straight and fine hair that does not curl or curve due to high oil secretions that make it soft and silk.

However, some men with type 1C hair might experience minor hair curving due to hair growing in straight locks due to some actions such as heat styling and combing. It is much easier for men to recognize their hair type because they wear their hair short most times.

Alopecia and balding can turn men’s hair into thin and straight strands. However, men with naturally straight hair can easily tell their hair type by checking how it bends from the scalp.

If the hair curves three inches from the scalp, you do not have straight hair, but if it does not, you might identify your hair as type 1. If your scalp and hair are incredibly oily by the end of the day, you could have type 1 hair.

If the hair falls straight off without much fuss, you have type 1 hair. Some celebrities with type 1 straight hair include Justin Beiber, Brad Pitt, and Tom Cruise.
