Why Do I Have Straight Hair with Curls at the Bottom?

Not only is your hair one of the best ways to showcase your personality, but also a symbol of seduction and physical attraction. Taking care of your hair is very important because it is a reflection of your identity. However, achieving healthy, happy hair is not always the easiest feat as a variety of external and internal factors affect how it looks, holds a style, and behaves.

Straight hair with curls at the bottom

Straight hair, in particular, is always in style because it is flattering, sleek, and makes one look effortlessly put together. However, those seeking to achieve the smooth and streamlined look straight hair offers are faced with a variety of challenges that can lead to frustration.

In particular, straight hair is often prone to curling at the ends, which not only ruins the look but makes your hair unruly and challenging to manage. Whether this problem is due to your environment, the products you use, or your hair type, follow along to understand the underlying causes of this issue and boost your confidence with smooth and healthy hair.

How climate affects your hair

Factors such as humidity, altitude, pollution, season, and local weather all affect your hair. For example, the hair of someone living in Los Angeles where the air is heavily polluted, warm year-round, and dry will have a much different care regimen than someone living in New York, which is subject to a varying climate and seasonal changes.

One of the greatest calamities to befall those looking to maintain their hairstyles is humidity. Human hair is extremely sensitive to humidity because the extra water in the air causes hydrogen bonds to form between the proteins in your hair. Moreover, the amount of moisture in the air changes the length of your hair, which can trigger curls, frizz, and a bad hair day.

The extra water in the air causes neighboring keratin proteins in your hair to become hydrogen-bonded to each other, effectively pulling your hair into a coiled shape. This problem is particularly bad for those living in humid environments, such as Florida, where it rains nearly every day.

Since human hair is porous, it is prone to absorbing whatever moisture is in the air. Hair that has been chemically treated is often drier than most and particularly susceptible to this issue because it is able to absorb more moisture. If humidity is a problem for your hair, it is best to treat it with a product such as the Living Proof Humidity Shield, which provides weightless frizz control by coating your hair in a deep-conditioning, humidity-resistant polymer.

Dry climates, however, pose a much different challenge to smooth, straight hair. The lack of moisture in the air causes your ends to become thin, coarse, and dry. This can lead to split ends, which take on their own shape and curl or bend regardless of how you style your hair.

If left untreated, split ends will continue to travel up the hair shaft, causing more and more of your hair to curl against your will and break off. Therefore, it is important to trim the very ends of your hair every 8-10 weeks to ensure it stays healthy and curl-free.

Additionally, it is important to treat hair exposed to hot and dry climates with a heat-protectant, such as the CHI 44 Iron Guard Thermal Protection Spray. This product helps to seal the hair cuticle to prevent damage. You can also treat your ends with lightweight hair oil, such as Verb Ghost Oil, to soften, defrizz, lock in moisture, and promote shine in dry hair.

How stress and hormones affect your hair

Stress and changes in hormone levels often do more harm than good to your hair. Excessive amounts of stress can cause spikes in the hormone cortisol, which is responsible for pushing your hair follicles into the telogen, or “resting,” phase. In this phase, hair will not grow. Additionally, high levels of cortisol can cause your hair to fall out and change its texture. Hair can become noticeably thinner, coarse, and dry which promotes curling at the ends.

To counteract the effects of stress, take a supplement such as OLLY Ultra Goodbye Stress Softgels, which contains botanicals such as Ashwagandha, L-Theanine, and Lemon Balm to promote stress relief. Moreover, you can indulge in self-care practices such as daily scalp massages which promote blood flow to the hair follicles and encourage healthy hair. You can also incorporate a hair oil, such as Jamaican Black Castor Oil, to hydrate your hair, encourage growth, and promote a healthy scalp.

How heat styling affects your hair

Hot styling tools such as flat irons, blow-dryers, and curling wands can make your hair look beautiful—but at a steep price. By applying excessive amounts of heat and tension to your hair, it can become coarse and prone to breakage. At high enough temperatures, bubbles can form on your hair and compromise its integrity.

Overusing hot tools will cause your hair to become extremely damaged and curl at the ends no matter what you do. Therefore, it is really important to use heat on your hair in moderation and to ensure you are doing everything possible to protect your hair when you do.

To avoid heat damage, it is recommended that you use tools with ionic or ceramic technology, such as the Conair Ionic Ceramic Hair Dryer. This technology allows you to style your hair at lower temperatures, which minimizes damage. Moreover, you should use the low heat settings on all of your hot tools to ensure your hair does not dry out and break off.

Although you should be air drying your hair to maintain its health, if you want to use hot tools, wait until your hair is at least 75% dry. This ensures your hair spends less time under intense heat for fast drying and less damage.

If you cannot stay away from hot tools, it is recommended that you always apply a heat protectant prior to styling your hair. Heat protectants act as a barrier between your hair and the heat of styling tools which slows down heat conduction and promotes even heat distribution.

To maintain your hair’s health, it is also recommended that you apply a deep conditioning treatment, such as Shea Moisture’s Deep Treatment Masque, every few weeks to promote healthy hair growth, seal the hair cuticle, and add a beautiful gloss and shine which can emphasize the beauty of straight hairstyles.


Your climate, hormones, and styling preferences can all affect the behavior and look of your hair. However, if you are conscious of how you are treating your hair, you can ensure it will look its healthiest. Straight hair is often prone to curling at the ends, so adjusting your styling routine with the weather in mind, maintaining a healthy diet, managing stress, and minimizing heat and humidity exposure can eliminate this problem.

Frequent haircuts, allowing your hair to air dry, using heat protectants, hair oils, and hair masks, brushing your hair regularly, and eating a nutritious diet are all great practices for maintaining healthy, shiny, and straight hair. Your hair will thank you if you take care of your health, are mindful of your environment, and maintain a healthy hair care
