Thickness Of Human Hair & Factors Affecting Hair Thickness

Have you ever thought about how thick human hair is? Our hair isn't just about looking good but also a vital part of our identity. This article will explore the question, "How thick is human hair?" We will also discover what makes our hair thick or thin.


Human hair thickness is like a fingerprint, unique to each person. We will learn about the things that decide the width of human hair, like our genes and hair color. We will also explore ways to make our hair thicker naturally.


So, let us dive into the world of human hair, where we will uncover the secrets of human hair size and width and learn how to make the most of our locks.


But before moving forward, let us first understand the thickness of a human hair in mm.


How Thick is Human Hair?


Thickness Of Human Hair

Human hair is an incredible natural feature that serves various functions, including protection, insulation, and identity. While each person's hair is different, there is a standard range for human hair thickness. The average thickness of hair can be described in terms of millimeters. The average human hair width ranges from 0.016 to 0.05mm.


Human hair is incredibly thin, even thinner than a tiny fruit fly's eye. To help you picture it, think about the fact that a human skin cell is 20 to 40 times thicker than how thick is a strand of hair. But here is the catch: the thickness of hair can be different for each person. It depends on factors like hair color, what hair is made of, and our genes – those things that make us who we are. So, everyone's hair can be unique in how thick it is.


Let us now delve into the factors that influence the width of a human hair.


Factors Influencing Hair Thickness


Some of the factors that influence the thickness of hair are explained below:


1. Hair Color


Color is a key element that significantly influences the assessment of human hair thickness. The pigmentation of our hair is primarily influenced by melanin, a natural pigment responsible for the color of our skin and eyes. There are two primary types of melanin: eumelanin and pheomelanin.


In the world of hair color, eumelanin is the key player. This melanin type is responsible for darker pigments, commonly found in shades of black, brown, and dark variations. Dark hair, such as black or deep brown, is usually thicker than its blonde counterparts. This thickness can be attributed to the higher concentration of eumelanin. Eumelanin-rich hair tends to be robust and sturdy, which gives it a thicker appearance.


On the other hand, blonde hair contains a higher proportion of pheomelanin, which results in lighter pigmentation. Pheomelanin is associated with a more delicate and finer hair texture, contributing to the thinner appearance of blonde hair. So, the color of your hair is not just a visual trait but also a factor that significantly affects the width of hair and its overall structure.


2. Hair Composition


The thickness of human hair does not depend on its color alone; it is also majorly influenced by its composition. A single strand of human hair is a complex structure composed of three fundamental components:


  • Keratin: Keratin is the dominant protein in human hair, making up approximately 80% of its structural composition. This vital protein provides strength and rigidity to the hair, forming a reliable support that determines its overall thickness and durability. It is essentially the building block that strengthens each strand, giving it its characteristic resilience.


  • Water: Human hair contains a significant amount of water, typically 10% to 15%. The moisture content in the hair is essential; it plays an important role in influencing the hair's suppleness and general appearance. Adequate hydration keeps the hair flexible and less prone to brittleness and breakage.


  • Lipids and Minerals: A hair strand's remaining 5% to 10% consists of lipids and minerals. These elements promote the overall health and appearance of the hair. Lipids help in maintaining the hair's shine and vitality, while minerals play a role in protecting its structure and preventing it from damage.


3. Genetics


Genetics plays a vital role in shaping the thickness of an individual's hair. Hair characteristics, including thickness, are often hereditary, passed down from one's parents. Genetic factors significantly influence both the quality and quantity of one's hair. For instance, conditions such as androgenetic alopecia, known as male or female pattern baldness, are inherently linked to genetic predisposition and can lead to hair thinning over time. In essence, our genetic makeup is a crucial determinant of whether we will have thick or thin hair, and it can also increase the risk of individuals to specific conditions affecting the width of hair, creating a familial pattern of hair traits.


4. Average Thickness of Hair


The average hair thickness can differ from person to person, but it typically falls within the range of 0.016 to 0.05mm. This measurement considers several factors that contribute to the thickness of hair, including natural color and genetic predisposition. It underscores the unique nature of each individual's hair and how various influences determine its thickness.


5. Hair Density


Apart from hair thickness, another aspect to consider is hair density. It refers to the number of hair follicles present on the scalp. The average human scalp contains approximately 80,000 to 120,000 hairs. However, this number can vary significantly from person to person based on factors like ethnicity, age, and hair color.


On average, there are around 800 to 1,290 hairs per square inch on the scalp. Interestingly, the number of hair follicles on your head roughly equals the number of strands. Both hair thickness and hair density are influenced by genetic factors, meaning that genetic conditions can significantly impact an individual's hair quantity and quality.


Ways to Naturally Make Your Hair Thicker


If you are interested in improving the thickness of your hair or addressing issues like thinning hair, there are several natural methods to consider. These methods enhance the overall health and appearance of your hair:


1. Hydrate Your Hair


Deep conditioning masks, hair oils, shampoos, and massagers containing essential ingredients and oils can work wonders for thin and brittle hair. Certain oils, such as castor oil, can stimulate hair growth and add thickness. Grapeseed and jojoba oil are hydrating agents that help maintain the hair shaft.


You can choose from various natural hair care products TLP offers, made with organic and natural ingredients. These products help promote healthy hair growth and maintain overall hair health.


2. Trim Regularly


Split ends can make your hair appear thinner at the tips and slow its growth. Regular trims, which can be done at home, can help eliminate split ends, promote faster growth, and give your hair a thicker appearance.


3. Add Biotin to Your Routine


Biotin, a type of vitamin, boosts the body's natural keratin production, a crucial component for hair, skin, and nails. While more research is needed to understand the full extent of biotin's effects, it's commonly recommended by experts in the field. You can find biotin supplements, shampoos, and treatments or incorporate biotin-rich foods like egg yolks, nuts, whole grains, and legumes into your diet.


4. Use Sulfate-Free Products


Parabens, silicones, and sulfates are common ingredients in many organic hair care products but may contribute to thin, lackluster hair in the long run. These chemicals can block the hair from absorbing essential nutrients and may lead to product buildup on the scalp, making your hair feel greasy and necessitating frequent washing. Transitioning to sulfate-free hair products may not produce the same foamy lather, but the long-term benefits are well worth the switch.


For instance, "Loving You" is a no-lather, pH-balancing, sulfate-free shampoo from TLP, and it's a must-have for a healthy hair care routine.


Conclusion

Human hair is a remarkable part of our identity and biology, with each individual's hair possessing unique characteristics. Understanding "how thick is human hair" and the factors that influence the thickness of hair, such as hair color, composition, and genetics, can help us appreciate the diversity of human hair. Whether you're looking to make your hair thicker or address issues like hair thinning, you can employ natural methods and strategies to improve your hair's health and appearance.


You can maintain healthy and beautiful hair by taking good care of your hair, staying informed about its characteristics, and using natural remedies to enhance its thickness. Remember that hair is not just a physical feature but also an essential aspect of self-expression and identity, making it all the more vital to understand and appreciate its unique qualities.
