They may become active as a result of environmental influences such as nutrition, stress, medication, sickness, or pollution. 

However, other elements all directly impact the number of hormones in the body, but pollution does not. Instead, bad air quality impacts hormones, causing hair texture to change.

Hormones changes

Hormones can also alter muscle tone, including your scalp, which affects the shape and growth direction of the hair follicles. 

Muscular alterations are expected during menopause, adolescence, and chemotherapy because hormones modify the hair follicle’s muscular tone. 

Besides, hormones change daily, notably when you get older. These hormonal fluctuations affect the condition and structure of your hair. 

Factors such as pregnancy, menopause, puberty, and birth control can all significantly impact the texture of your hair.

During puberty, there is a significant fluctuation in the hair’s texture. Pregnant women frequently notice any changes in their hair and skin. 

Even when one person is not pregnant, pregnancy hormones still play a part in these alterations. These hormones are created during each menstrual cycle or once birth control is used.

During menopause, the body undergoes several hormonal changes which begin to manifest on the surface, including the hair getting dry and wiry when you age.

The shift in your hair texture may be dramatic at times. Once the muscles in your hair follicle shaft, the follicle’s shape changes, causing your straight hair to turn wavy or vice versa.

Regarding hormones causing hair to become curlier, androgens are a great example. They are known as male hormones responsible for developing and maintaining male traits; nevertheless, androgen levels rise in both girls and boys during maturation. 

These hormones result in increased body hair and baldness in both genders. An excess in androgens found in females may cause the hair follicle shape to shift from round to flattened, as well as its texture to alter from flat to wavy.

Climate varieties

The same humid conditions that cause straight hair to go flat may also improve your curls or change loosely curly hair into tight curls. It can occur on a very humid and wet day in your usual area, or it may happen when you relocate or travel to a stickier region.


Many people claim to have noticed a permanent difference in their hair after getting a wavy perm. 

Perms use heat and chemicals to enter your hair follicle and restructure the protein connections. This technique can cause long-term harm to the hair follicle, causing your hair to curl from that point forward.


Changing medications for disorders such as switching to nontoxic items, bipolar disorder, or following a new, particular diet can all work to minimize the number of metals in your body.

Although research into these issues is still in its early stages, many people have experienced a difference in their hair and health after determining which metals were overly present in their system. Metals such as copper, for example, have been related to hair curl. 


Several cancer medications like epidermal growth factor receptor inhibitors may affect your hair texture, which causes hair to become wavy or straight.

Like the way hormones can influence hair texture, drugs that impact hormones, like thyroxine or glucocorticoids, can cause hair to curl.

Nutritional changes

A diet deficient in essential minerals and vitamins might significantly impact your overall hair texture. Besides, a rise in minerals in multivitamins and specific diets has been proven in tests to promote wavy hair curls.

Therefore, if you have recently observed that your straight hair turns wavy, check your diet and see if any significant changes have happened.

Environmental exposition

You can avoid chemicals, but it is difficult to protect you from the sun’s dangerous UV radiation. The atmosphere out here is severe, and the hair is in danger of changing texture, lustre, and look in some way.

Exposure to strong sunlight without hydrating the hair causes it to become brittle and dry, resulting in wavy hair over time. 

Can Stress Make Your Hair Go Curly?

Yes, it can. In addition to hormones and aging, stress is the most common reason for changes in your hair quality and texture.

Stress can cause your hair to get curlier. 
Stress can cause your hair to get curlier.

Stress is terrible for your body and even your hair. Once you are stressed, the kind and quantity of hormones existing in the body can cause alterations in your hair texture.

If you are under stress, your body produces the hormone called Cortisol. When the levels of this hormone are too high, it has the potential to abbreviate the Anagen, or growth stage of a hair cycle.

Once this occurs, greater hairs than the usual transition from the Anagen to the shedding phase or Telogen. As a result, your hair becomes thinner and loses volume. Then, your hair may become curlier as less weight pulls down on your hair.

Why Is My Hair Curly Underneath But Straight On Top?

Mixed hair type

The first cause is that your hair type is mixed, which means you have a blend of straight and wavy hair textures on your head owing to genetics. 

It is critical to remember that the gene responsible for frizz is indeed not dominant. Instead, it is just dormant for a period before becoming active, which changes the form of the hair follicles. 

Thus, it affects the new hair growing from it. Other factors, such as lifestyle, genes, and anxiety, also influence your hair texture.

You can flatten or perm these two layers to equal the texture to remedy this issue.

Lack of moisture

Aside from flattening damage, the top layers are not curling as much because this part of your hair dries first, whereas the layers underneath remain damp longer, enabling the normal curl pattern. 

Also, it is yet another sign that the hair requires more hydration if you need it to be fully wavy.

Top layer’s nature

Upper layers are more vulnerable to hair-care chemicals than bottom layers. The quantity of products applied to the hair on the top does not reach the bottom. 

As a result, the wavy hair on top can not be maintained and becomes straightened.

Second, when hair becomes longer, it lowers down the top layer, making it look straighter than the rest of your hair.

Furthermore, since the hair on the top is easily touched, once hair comes into frequent direct contact with the sun, pillows, or other surfaces and substances, it loses its curls on the top layers.

Mainly, prolonged sun exposure can straighten the surface layer of your wavy hair and damage it.

What Should I Do When My Hair Turns Curly Underneath But Straight On Top?

Utilizing heat

First, see your hair and decide whether you want it wavy or straight. Once you like wavy hair, use a curling iron to curl the top layer to resemble the structure of your waves. 

However, if you want to keep the hair straight, maintain the top layer and flatten your wavy hair with a high-quality straightener if you want to keep the hair straightener.

Use the proper hair products

Prioritize silicone and sulfate-free hair care products because silicone may weigh down your hair and lead curls to flatten out. 

Likewise, silicone can cause your hair to dry out faster. Sulfates may remove hydration from the hair, causing it unhealthy and dry. They also cause your scalp to become dry and irritated.

The result is that wavy hair might become flat after the top surface dries up.

If you choose to use silicone-based hair products to enhance slides, look for those containing water-soluble silicones. Then, they may result in less build-up, although it is advisable to stay away from these items entirely.

Make use of holding gels

These products can keep your ringlets for an extended period. As a result, always apply a little to your top hair surface. 

Also, you can twist the wavy lock around the finger with holding gel to ensure that it stays curly for a prolonged time.

Use root lifters and curl activators

The roots of your hair are in charge of maintaining the total weight of the hair. As a result, boosting them may result in higher hair volume as well as more distinct waves.

On the other hand, curl activators may assist in activating and shaping your curls. If you want curly hair, we recommend using these two products to enhance the curl structure in the hair.


As previously mentioned, lack of moisture is among the reasons your hair is curly underneath and straight on top. Therefore, moisturizing it is essential.

Once your hair is damp, it is curlier than if it is dry. Therefore, hydrate the hair frequently to preserve the hydration on your top hair surface, which helps a little with keeping a natural curls pattern.

When your hair is still wet, pin it up

When the hair is wet, divide it into little sections and tie it until it dries. So, this procedure will provide a much-needed push to the roots of the hair, leading to more distinct curls.

Have a haircut

When your hair grows longer, it turns thicker and weighs down your head, causing the upper surface to look straighter than underneath. 

Then, a haircut is an ideal remedy to this problem. The hair will lose weight and revert to its curled pattern.

Furthermore, trimming hair reveals the wavy hair pattern beneath while hiding the straight top layer. However, you should not try this on your own because the needed haircut is not easy. 

Alternatively, address the issue with your hairdresser to get an appropriate trim without causing damage to the style.

Stay away from ponytails 

It is due to the fact that keeping a ponytail stretches and bends the front hair strands, enabling curls to come out. 

Therefore, maintaining your hair out of ponytails will help it progressively restore its curls.

You had better stay away from ponytails as much as you can.
