Wondering how to tell the difference? You can learn more about coarse hair type right here. It is usually thick and does not break easily. Identifying your hair type can help you take care of it properly. In addition, you can learn the specific products it needs and the more flattering hairstyles for such hair types. So, go ahead and scroll down to figure out if you have coarse hair.

What Does Coarse Hair Mean?

Coarse hair is different from curly, kinky, and frizzy hair. There is only one determining factor when it comes to coarse hair its diameter! It has the thickest diameter compared to all other hair types. To be precise, it is composed equally of all the three layers of the hair shaft (cortex, cuticle, and medulla), unlike any other hair type. This hair is generally thicker than a sewing thread. You can feel its thickness if you roll it in between your fingers. However, this hair type needs more time to absorb moisture and quickly loses its luster. Hair porosity also plays an important role in this. Strands with low porosity tend to be coarser and frazzled. Hence, it needs the right hair care products for maintenance.

Fun Fact

The cuticle (outermost layer) protects the hair and holds its shine. The cortex (middle layer) contains the color pigments, and the medulla (the core) contains DNA information.

How To Identify Coarse Hair

Hair stylists say it is easy to confuse coarse hair with curly hair. They are very different and have various hair textures. Coarse hair typically has thicker hair circumference than most hair types.
There are three factors that are essential for determining different hair types: the diameter, density, and elasticity of your hair. The good news is once you identify your hair type, the right steps and intervention can make it easy to manage coarse hair.

1. Diameter

You cannot determine the diameter of your hair just by staring at it.

Process

To find out if your hair is fine, medium, or coarse, hold a strand between your fingers.

• If you cant feel the hair strand between your fingers, you have fine-textured hair.
• If you can feel the hair strand between your fingers, you have medium-textured hair.
• If you can distinctly feel the presence of a rough hair strand between your fingers, you have coarse hair.

2. Density

Figuring out the density of your hair is another way of determining your hair type.

Process

Grab a handful of your hair, pull it to one side, and check how visible your scalp is.

• If you have fine hair, you can clearly see the scalp.
• If you have medium hair, your scalp will be somewhat visible.
• If you have thick hair, your scalp will not be visible at all.

3. Elasticity

This step will not only determine your hair type but also help you figure out how healthy your hair is.

Process

Pull out a hair strand and slowly stretch it between your index fingers and thumbs.

• If it breaks immediately, your hair has low elasticity.
• If it stretches up to 50 % and returns to its original length when released, your hair has high elasticity.
• Fine hair has low elasticity, medium hair has average elasticity, and coarse hair has high elasticity.

Coarse hair is very dry when compared to other hair types and hard to manage. Having coarse hair can cause some problems, like frizz and brittle strands. Find out more about coarse hair problems in the following section.

What Are Some Common Coarse Hair Problems?

Coarse hair tends to get dry easily. You can also feel the roughness of your hair strands. Coarse hair is also prone to frizz and brittleness. If you have coarse hair, you can get silky, smooth, and shiny hair with the use of the right hair care products.

Some people have naturally coarse hair due to their genes. But if you have always had normal hair and are starting to notice your hair getting coarser, it can be because of several reasons. Scroll down to the next section to find out what they are.

Causes Of Coarse Hair

• Hormonal Imbalance (Hypothyroidism)

The thyroid hormones secreted in your body directly affect the health of your hair. Insufficient secretion of these hormones causes hypothyroidism. Hypothyroidism disrupts the structure of your hair follicles. As a result, the quality of your hair diminishes, and it starts turning frizzy.

According to an analysis of the Optum administrative claims database along with the National Health and Nutrition Examination Survey, the prevalence of hypothyroidism in the United States increased from 9.5% in 2012 to 11.7% in 2019. During the same period, the percentage of patients with untreated hypothyroidism (HT) rose from 11.8% to 14.4%. These findings indicate a steady growth in the prevalence of hypothyroidism in the United States since 2009.

Regular Heat Styling

Styling your hair with blowdryers, straightening irons, or curling irons on a regular basis strip away its moisture and reduces the secretion of sebum. The natural oils keep your hair moisturized and prevent frizz. Thus, a reduction in their secretion can make your hair coarse.

• Harsh Chemical-Filled Products

Shampoos that contain SLS are a complete no-no. They strip your hair of its moisture. Over time, this leads to dryness, and your hair becomes coarse. It then causes breakage. Limit using hair relaxers and undergoing coloring treatments like hair lowlights or hair highlights as they introduce harsh, dehydrating chemicals to your mane. It is best to wash your hair on alternate days with a sulfate-free or organic shampoo.

Calcium Deficiency

Calcium is essential for blood circulation, which plays an important role in maintaining the health of your hair. Calcium deficiency can ruin the texture of your hair and cause hair fall.

Furthermore, iron deficiency, genetics, and certain medical conditions can also cause coarse hair. If you have never had coarse hair in your life and are suddenly facing this problem, it can be a pain to deal with. Fortunately, there are some simple steps you can take to improve the texture of your hair. Just keep scrolling!

How To Take Care Of Coarse Hair

1. Oil Your Hair Regularly

Coarse hair lacks moisture and is often associated with low secretion of natural oils from your scalp. Hence, it is important to oil your hair regularly. Apply generous amounts of oil, especially on the ends. You can opt for adding simple organic coconut oil to your hair care routine. This will keep your hair moisturized and make it more manageable. It enhances hair bounce too. Oil your hair before going to bed and leave it on overnight. Wash your hair the next morning with a gentle shampoo. Repeat this process twice a week.

2. Try Deep Conditioning Masks

Deep conditioning is the best way to keep your coarse hair healthy. Hair masks are a great way to moisturize, soften, and soften coarse hair. DIY hair masks with natural ingredients like coconut, avocado, olive oils, and aloe vera can provide added nourishment to your dry, coarse hair. These natural plant oils also reduce frizz and soften your coarse hair. You can also add a few drops of your favorite hair serums to promote hair hydration. It may also boost hair strength. Scalp massage with these hair oils can reduce the dryness of your hair and also increase its thickness (1).

3. Limit Heat Styling

Even though coarse hair is the strongest of all hair types, overuse of heat styling tools can strip off all the moisture from your strands. This makes your coarse hair frizzier, drier, and unmanageable. So, you should limit the usage of heat styling tools. If you still want to use hair styling tools, make sure you apply a heat protectant first. While using a blowdryer, keep it 6 inches away from your hair to prevent heat damage (2).

4. Invest In Good Hair Products

Good hair care products here refers to products that are specifically formulated for coarse hair. Use shampoos containing fatty acids and antioxidants that help in nourishing the outer layers of your hair shafts. They keep your hair moisturized and free from breakage. Also, do not rub your hair vigorously while shampooing it as it can cause frizz or tangles.

5. Regular Trimming

Coarse hair is prone to breakage and split ends due to the lack of moisture. Trim your hair once every 7 to 8 weeks to remove the dead or dry ends. It will make your hair more manageable. Regular trims can help improve the look of your hair by removing the split ends. Also, it will make your hair look thicker and shinier.

6. Avoid Alcohol-Based Hair Products

Alcohol is the main ingredient in many hair care products. But, it has a drying effect on your hair. It also makes your hair more prone to damage. Although alcohol-based hair products help tame your coarse hair, they also strip off its moisture. Since coarse hair is drier than other hair types, try to opt for gentle, alcohol-free formulas for your coarse hair.

7. Co-Washing

Also known as the no-poo method, co-washing is quite common among curly-haired women. It involves washing your hair only with a conditioner. Instead of a shampoo, you use a conditioner to rinse out the dirt. This prevents dryness and keeps your hair moisturized. This reportedly works best on curly or frizzy women. Since this method is primarily used to get soft hair instantly, it works well in improving the texture of coarse hair.

8. Adopt Protective Hairstyles

Coarse hair, when left untied, attracts dust and dirt and is more prone to getting tangled. Detangling coarse hair can be a real nightmare as it leads to some serious breakage. Hair protective styles reduce the hassles of hair combing and prevent breakage. So, tie your hair up in a pretty braid or an elegant bun to protect it from these stressors while still looking cute!

9. Switch To Silk Pillowcases

Sleeping on cotton pillowcases is one of the main causes of dry hair and split ends. Silk pillowcases provide a smooth and frictionless surface that is gentle on your hair. This makes hair detangling easier and they also absorb less moisture. This means they may help your strands retain their natural oil and moisture, boosting hair shine.

10. Opt For The Right Type Of Hair Brush

Hair brushes play an important role when it comes to managing every hair type. Just like straight tresses benefit more from paddle brushes, coarse hair also requires a different type of hair brush that allows easy brushing without unwanted tugging and hair breakage. Individuals with coarse hair can opt for a boar bristle brush or one with nylon bristles. These brushes help in reducing static, thereby preventing friction and improving your overall hair texture. They also help in evenly distributing the natural hair oils throughout the entire hair length, which aids in reducing dryness and keeps the strands manageable.

Coarse hair is different from thick, curly, or kinky hair. Find the exact difference between these hair types in the following section.

What Is The Difference Between Thick Hair And Coarse Hair?

• Coarse Hair

Coarse hair refers to the thick circumference and rough texture of each hair strand. It has a wider diameter when compared to other hair types.

• Thick Hair

Thick hair refers to the number of hair follicles on your scalp and how much hair you have on your head. Therefore, the thickness of your hair determines its volume. Thick hair has nothing to do with the size of each hair strand. Your thick hair can have a fine or medium texture, as well. Furthermore, this hair type is prone to frizz and breakage.

• Curly Or Kinky Hair

When you use the words kinky or curly to describe your hair, you are actually talking about its curl pattern. The texture of your curly hair can be fine, medium, or coarse. Its a common misconception that kinky hair is coarse. This could not be further from the truth. Kinky hair is the most fine-textured and fragile of all hair types. Also, this hair texture is more prone to breakage than other types.
