The Science Behind Curly Hair: Understanding Your Curls


Curly hair is a trait that many people envy. However, not many people know the science behind curly hair, including the people who have it. If you’re among them don’t feel bad.


In fact, some manufacturers simply changed the wording on the bottles to brand it as a product for curly hair, without changing a single ingredient. This leaves you with a product that’s not meant for your hair. However, it’s not always the fault of the manufacturer, because products formulated for curly hair may not work for all curly girls.


We want to put the health of your hair back in your own hands. We are going to explore the science behind curly hair, including its genetic components, hair structure, and hair care.


Genetics of Curly Hair:



If you have curly hair, it’s a high probability that someone in your family also has curly hair like your parent or grandparent. In fact, one study found that curly hair is a dominant trait. For example, if one parent has curly hair, their children will also more likely have curly hair. However, the type of curly hair (3C or 4C) can vary based on the combination of genes you inherit from your parents.


One of the genes that determine the curliness of your hair is the trichohyalin gene. This gene forms the trichohyalin protein, which plays a critical role in the development and shape of the hair follicle. This in turn affects the texture and curliness of the hair.


Another gene that influences hair curliness is the KRT86 gene. It produces a protein called keratin. Just so you know our hair, nails, and skin is the primary component of keratin. The KRT86 gene influences the structure of the keratin filaments, which can affect the shape of the hair strand.


Hair Structure and curl pattern:



The unique shape of curly hair is due to the structure of the hair strand. Unlike straight hair, which is round, curly hair is oval-shaped or flattened. The shape of the hair strand influences the hair’s curl pattern and affects how the hair naturally falls.


The shape of the hair follicle is important because it determines how curved the hair strand will be. Curly hair follicles are more asymmetrical than straight hair follicles, giving the hair strand a unique shape.


Hair Care for curly hair:



Understanding the structure and genetics of curly hair is important for properly maintaining and caring for it. Here are some simple tips for caring for curly hair.


  1. Moisturize- curly hair is more prone to dryness due to its structure, which can lead to frizz and breakage. To combat dryness it is important to moisturize regularly. The best form of moisture is water. You should then add a water-based conditioner or cream. Remember oil is not a moisturizer! Oil is a sealant. It should be applied after the hair is dry. If you don’t believe me try mixing oil and water.

  2. Comb gently- Avoid detangling when the hair is dry. This can cause breakage and even damage. Instead, do all your detangling after applying your products on your wash day. The best tools for detangling are your fingers, wide-tooth comb, or detangling brush.

  3. Avoid heat styling- Heat styling tools like blow dryers, flat irons, and curling irons can cause damage, sometimes permanent, to curly hair. If you insist on using one of these tools, use a heat protectant to minimize damage.

  4. Trim as needed- Regular trims can help maintain the shape and health of your curly hair by removing split ends and preventing damage. Removing damaged ends will also help to prevent single-strand knots and tangles.


Conclusion:


Having curly hair is a unique and beautiful trait. Understanding the science behind your curly hair can help you better care for and maintain its health and beauty. By moisturizing regularly, combing gently, avoiding heat, and trimming as needed, you can keep your hair looking its best.
