Why is my hair straight on top and curly underneath

Why is my hair straight on top and curly underneath?

The top layer of your hair is straight and curly underneath because you probably have a mixed hair type. That is, your top layer is straight, and your bottom layer is curly.

To fix this, you can choose to either have a straightening or a perm done on both of the layers.

If you don’t want to follow these procedures, here are some alternatives: always use specific products for straight hair, protect it from external agents like heat and sun and adopt some healthy habits such as regular haircuts.

You may be here because you’re dreading the thought of having two types of hair: one that’s straight and curly, and another that’s very different underneath.

Do you have curly hair?

I have news for you. Your hair may not be as straight as you think. You may feel that the top layer is straight and the bottom layers are curly. That is because you have mixed hair.

But other factors make your hair straight, such as the products you use, the water you wash it with, and even the sun.

When you use heat tools like curling irons, blow dryers, and straighteners, the top layer of your hair becomes thinner and less curly . It’s also more likely to frizz.

Do you want to change your straight top layer?

You won’t achieve it by magic. So, stay with me, because I’ll tell you:

  • Why the top layer of your hair is straight and curly underneath
  • What type of treatment should I use and how can I unify the textures of my hair?
  • Some alternatives to try that seem to have worked for others


There are many types of hair out there, but the point is figuring out what kind your hair is. What exactly does it have to do with the straight hair layer?

There are four main types of hair – straight, curly, wavy and afro.

But in this life, there are also gray areas. So, there’s also mixed hair.

If you have curly, wavy or straight locks, you are in for a diverse set of arrangements. Afro & straight combinations are different from the other two because the difference between layers is easier to notice.

In the world of hair, nothing is quite as it seems. For example, straight hair can have some natural movement.

That’s why you have to know your hair type to find the right solution.

Mixed hair is the most common type of natural hair in women, particularly those who live around the world. It can be curly on top and straight on bottom or vice versa.

Find out what specific treatments for your hair type


Want to unify the two textures of your hair without undergoing too much effort? A perm or straightening can do the job. This will even out your hair strands and you won’t have to deal with any split ends in the future!


If you comb your hair making sure all parts of your hair are relatively aligned, the bottom layer will be curl and the top layer straight.


If you prefer to wear your hair curly, you can opt for a perm on your top layer to match the bottom layer.

On the other hand, if you don’t like to perm or straighten your hair, you can improve its look by working with the top layer. That’s what this section is about.


What are your hair care habits?

Many people don’t realize that they should use hair products that are tailored to their hair type in order to properly care for it. I’ve noticed this in my own experience.

One of the interesting things about water is that in some areas, it has a higher weight because it contains many minerals or even lime.

Hair fibers contain minerals which make them heavy. The upper layers of such hairs are straight while the lower ones are wavy.

Why is that?

Bottom line: The upper layers are more exposed

It’s important not to overreact by moving from the area. However, you can choose some products that counteract the harm they do.

For example, hair products that don’t have keratin or protein in them. Do you know why?

Curls are more fragile than straight hair, because the molecular composition is lighter. Therefore, your curls need way more structure to behave properly.

If you apply those products to your layered hair, the straight layer will get even straighter due to being weighted down.

What’s the solution?

The use of hair products for straight hair is more effective as they have a lower molecular weight and will leave your hair looking perfect.

There are different shampoos, conditioners, and masks for straight hair people.

Any hair care products you use for straight hair will give the top layer of your hair a curlier appearance and, therefore, will match the rest of your hair.

Now, your job doesn’t end there.


The top layer is the most susceptible to damage by external factors since it’s exposed to everything that comes into contact with the hair.

Contact with chemicals, sunlight, aerosols, perfumes, rain and many other environmental factors can all have a damaging effect.

The top layer of the hair becomes more damaged and frizzy in comparison to the bottom layers. But there are a few tricks you can perform in your daily routine to avoid this without a lot of investment

  • Wear a hat to protect your head from sun damage!
  • Apply a spray of micellar water onto your hair every two or three hours to moisturize it.
  • Use a coconut oil from root to tip to repair your hair and thickens the hair fiber. You can do this a couple times a week
  • Clips are a good option for pulling hair back. They let you put your hair back without affecting its natural shape too much, which might be good if you want to wear it straight later on!
  • Brush your hair from the bottom to the top with a wide toothbrush.

If you follow these guidelines, your top layer will be repaired in a short time and it’ll no longer look straight and frizzy.


The top layer of your hair is straight and curly underneath because you probably have a mixed hair type.

You can choose whether to straighten or curl your hair to make its texture more uniform. We also recommend you make some changes to your hair care routine.

If you have straight hair, try using products made for straight hair and to protect them from external elements.
