So let’s explore the mystery of wavy hair underneath and straight hair on top, and discover the secrets to unlocking your best hair yet.

Hair is a defining characteristic of human beings and an integral part of their personality. However, many people experience different hair textures on different parts of their scalp. This can be perplexing, especially when your hair is wavy or curly underneath but straight on top. In this article, we’ll explore the science behind this phenomenon and provide some practical solutions to help you achieve a consistent look.

Genetics of Hair is Wavy or Curly Underneath

Genetics plays a significant role in determining hair texture. Different parts of the scalp have different hair follicle shapes, which can affect the texture of the hair that grows from them. For example, the hair on top of your head may be straight because the hair follicles are round, while the hair underneath may be wavy or curly because the hair follicles are oval or flat.


Hormones are another factor that can affect hair texture. During puberty, the body goes through significant hormonal changes, which can affect hair growth and texture. Similarly, during pregnancy, hormonal changes can cause changes in hair texture, leading to hair is wavy or curly underneath and straight hair on top.

Heat Styling Is Major Reason For Curly Underneath Hair

Heat styling tools, such as flat irons or curling irons, can damage hair over time and affect its texture. Using these tools frequently can lead to straight hair on top and wavy or curly hair underneath. This is because the heat damages the hair cuticles, making them more susceptible to damage and breakage.

Hair Care Routine

Your hair care routine can also affect your hair texture. Using harsh shampoos or not conditioning your hair properly can make it frizzy or difficult to manage. Similarly, over washing or under washing your hair can lead to dryness or excess oil, affecting its texture.


There are several remedies you can try to achieve a more consistent look: 

  • Embrace your natural texture: Instead of trying to fight against your hair’s natural texture, try embracing it. Experiment with styles that work with your waves or curls, such as braids or loose updos.
  • Use heat styling tools sparingly: If you must use heat styling tools, make sure to use them sparingly and always use a heat protectant spray to minimize damage to your hair.
  • Invest in quality hair care products: Using high-quality shampoos, conditioners, and styling products can help improve the overall health and texture of your hair.

Creative Ideas

There are several creative ideas you can try to add interest and texture to your hair:

  • Try a half-up, half-down hairstyle that showcases your natural waves or curls on the bottom half of your hair.
  • Create a braided headband using the hair on top of your head to accentuate the waves or curls underneath.
  • Experiment with different hair accessories, such as headbands or hair clips, to add interest and texture to your hair.

Loving your hair and boosting your confidence starts with embracing your natural hair texture and finding a hair care routine that works for you. This includes using the right products, protecting your hair from damage, and embracing your unique beauty.
