Why Is My Hair Curly Underneath But Straight On Top

You're not alone if you have curly hair on the bottom and straight hair on top. There are a few reasons this may be the case. Keep reading to find out more about why your hair might be like this.

Why Is My Hair Curly Underneath But Straight on Top?

There can be many reasons for having curly straight hair. One of the main reasons for this is genetics and there is pretty much nothing you can do about your genes. Many people's hair consists of both curls and straighter, wavier layers.

Dealing with two types of hair can be frustrating because they often need different levels of care. It's also hard to style straight or curly hair when you have a mix of both textures on your head.

If you have a mix of curly and straight hair, you probably know why. But if you want to get the top layer to curl more, here's how.

Top Reasons Why Hair Curly Underneath Straight On Top

While damaged hair is often characterized by being straight on top and curly underneath, there could be other issues at work.

Here are a few reasons why your hair may be curly at the bottom but straight on top:

  • Genetics. The gene for frizz is recessive. The genes can remain inactive for some time until it becomes active and changes the shape of hair follicles. This, in turn, affects the new hair that grows from them.
  • Lifestyle. Heredity, stress levels, and other lifestyle choices can all affect your hair pattern.
  • Health Stats. Your fitness levels can also affect your hair styling. For example, people with thyroid disease may have thinning hair that doesn't curl due to hormonal imbalances.
  • Bedding. If hair frequently comes into contact with pillows and other surfaces, it can lead to the top layers losing their curl pattern.
  • Excessive Sun. Sun overexposure may lead to straightening of the top layer and weaken your curly hair.
  • Excessive heat styling can damage the top layer of curly hair and cause it to lose its curl.
  • Product Use. Styling products such as gel and mousse can weigh down your hair, making it appear straight.

Included in this article is an explanation of how to preserve your hair's natural curl, as well as a list of products and procedures you should avoid.

How Can You Get The Top Of Your Hair To Curl Like The Bottom?

If you want your entire head of hair to curl, use a curling iron or hot rollers; get a perm or chemical relaxer.

Please be cautious- if not done correctly, some of these methods could damage your hair beyond repair. Before you start, speak with a professional who will be able to help you get the look you desire without harming your strands.

Anyone can achieve curly hair, even if you have naturally straight locks. You only need a bit of time and patience to sleep with your hair in braids or twists. Usually, people will see at least a minor change in their hair's curl pattern 

What Makes Someone Have Curly Hair?

There are a few things that can affect the curl pattern of someone's hair. The shape of the follicle, the amount of sebum produced, and weather conditions can all play a role in how curly or straight someone's hair is.

The genetics of curly hair is still not fully understood. What we do know is that the gene for curly hair is recessive, meaning that both parents must have the gene for a child to inherit it. Additionally, the gene can remain inactive for some time before becoming active and changing the shape of the hair follicle.

Sebum is an oily substance produced by the sebaceous glands that prevents hair from drying out and breaking. Usually, people with curly hair have less sebum production than those whose hair is straight. As a result, their locks are often dry, frizzy, and tough to manage.

Finally, weather conditions can also affect the curl pattern of someone's hair. High humidity levels can cause the hair to swell and lead to frizz, while low humidity can cause the hair to become dry and brittle.

What Causes Straight Hair To Become Curly?

When females have an increase in androgens, it can cause the shape of their hair follicle to change from round to flat. This transformation also changes the texture of the strands from straight to curly.

How To Make Your Hair Curly Naturally?

Either let it air dry or diffuse it. Create natural waves by allowing your hair to air dry for about 90% of the time, then blow-drying with a diffuser on the lowest setting.

For more defined curls, hold strands of hair in the palm of your hand and scrunch upwards while blow-drying. You can also use a curling iron on poker-straight strands.

What Are The Best Products For Half Curly And Half Straight Hair?

If the top of your hair is curly and the bottom is straight, you might be wondering which styling products to use.. Rest assured, there are a few options available that cater to different types of hair textures. The best product for you will come down to your personal preferences.

If you have naturally straight hair and want to curl it, you can use a curling iron or hot rollers on sections of your hair that are already curly. In addition to this, you can use products that assist in managing frizz and give definition to your curls. These items might be leave-in conditioners, hair masks, gels, hair serum etc.

Although often overlooked, rubber bands can damage your hair if used too frequently.

Your stylist knows best. Discuss with them what style you want and how to achieve it given your hair type. Their expertise will help you choose the products that will give you the desired look.

Wrap Up

Most people's hair falls into more than one category.

Perhaps you know several people with a hairdo that falls somewhere in between curly and straight.

Whether we love or hate our hair, the most crucial thing is that we don’t style it to match someone else’s concept of beauty. Remember, there is no one standard for gorgeous hair.
