Key Points

  • Dry hair occurs because of genetics, scalp sebum, diet, styling habits, environmental factors, or the structure of your hair shaft.

  • Prevent dry hair or improve your hair by avoiding heating tools, using the right shampoo and conditioner, getting regular trims, and incorporating a hair serum into your routine.

  • Ingredients like argan oil, coconut oil, shea butter, and honey absorb into your hair to provide moisture and seal your cuticle.

  • Apply a bit of hair serum for dry hair every day when your hair is damp, starting at the ends and working up to mid-shaft.

Don't leave your hair sad, dry, and frizzy. Nourish and moisturize your hair with these incredible serums to lock in moisture and prevent more damage.

Challenges of Dry Hair

Dry hair is a common hair problem that affects people of all ages. It's caused by a lack of moisture in the hair shaft, making it look dull, frizzy, and unmanageable.

It's more challenging to detangle dry hair, which can be painful and frustrating as you try to run a brush or comb through it. When hair lacks moisture, it's more prone to breakage because it's not as strong as healthy hair. This is incredibly challenging if you have long hair, as it makes your hair look shorter and thinner. Fragile, dry hair develops split ends much faster.

If your hair is already dry, it's more prone to damage from heat styling, coloring, and other environmental factors. This makes dry hair even more dehydrated, and your hair is likely visibly unhealthy and damaged. Additionally, dry hair doesn't hold color as effectively as healthy hair due to the porous cuticle.

It's more difficult to style dry hair because it doesn't hold shape as easily as healthy hair. It's frustrating when you try to style your hair differently, but your hair doesn't stay put. Dry hair is also more prone to static electricity, which makes it appear puffy and unkempt.

What Causes Dry Hair?

The biological and scientific reasons for dry hair aren't fully understood. However, it's thought that the lack of moisture in the hair shaft is due to a combination of factors, including:

  • Production of sebum: Sebum is an oily substance produced by the sebaceous glands in the scalp. Sebum helps to keep hair moisturized. However, people with dry hair often produce less sebum, leading to dryness.

  • Structure of the hair shaft: The hair shaft has three layers: the cuticle, the cortex, and the medulla. The cuticle is the outermost layer that protects the hair from moisture loss. In people with dry hair, the cuticle is likely damaged or missing, which can make the hair more prone to dryness and damage.

  • Environmental factors: The environment can also play a role in dry hair. Dry weather, hot water, and exposure to the sun or wind can all strip moisture from your hair.

  • Genetics: Some people are simply more prone to dry hair than others.

  • Hormonal changes: Hormonal changes, such as those that occur during pregnancy or menopause, can cause dry hair.

  • Medical conditions: Some medical conditions, such as thyroid problems and diabetes, can also lead to dry hair.

  • Diet: A diet low in protein or essential fatty acids can contribute to dry hair.

  • Styling habits: Excessive heat styling, coloring, and bleaching dry out hair.

Managing Dryness

If you have dry hair, there are several things you can do to manage it. Try the following tips to give your hair the moisturize it deserves:

  • Use a moisturizing shampoo and conditioner: Look for products specifically for dry hair. These products add moisture to the hair and make it easier to manage.

  • Avoid using hot water when washing your hair: Hot water strips moisture from hair, so it's best to use warm or cool water instead.

  • Use a leave-in conditioner: A leave-in conditioner keeps your hair moisturized throughout the day.

  • Avoid heat styling your hair: Heat styling can damage your hair and make it more dry. If you use heat styling tools, apply a heat protectant first.

  • Get regular trims: Regular trims help to remove split ends and damaged hair, avoiding further damage and tangles.

  • Eat a healthy diet: A diet rich in protein and essential fatty acids helps keep your hair healthy and moisturized.

  • Hair serum: Hair serums nourish the hair and coat the cuticle to lock in the moisture. These serums also control frizz and protect hair from heat exposure.

Utilize a Dry Hair Serum

Hair serum is a lightweight styling product that adds moisture, shine, and protection. Moisturizing hair serums contain ingredients such as oils, butter, and humectants. This combination of ingredients coats the hair shaft and prevents moisture loss.

The cuticle is the outermost layer of the hair shaft, made up of overlapping scales that protect the hair from damage. When the cuticle is damaged, it can make the hair dry and frizzy. Hair serum smooths the cuticle and makes the hair healthier and appear shinier, reducing the inevitable frizz of dry hair while protecting it.

Heat styling is harmful to dry hair. Heat damages dry hair even more severely than it does healthy hair. Hair serum protects the hair from heat damage by creating a barrier between the hair and the heat styling tool.

Choosing the Right Serum

There are countless kinds of hair serum available on the market, such as those for volume, balanced color hues, combating frizz, promoting growth, and more. Check out The Ordinary Hair Serum and Divi Hair Serum to encourage hair growth.

If you need to combat dry hair, look for serums formulated specifically to treat dry hair. Consider these additional factors when choosing a dry hair serum.

Hair Type

If you have fine hair, you'll need a lightweight serum that doesn't weigh your hair down. Look for serums labeled as "weightless" or "oil-free." You may need a heavier serum that provides more moisture for thick or coarse hair. Look for serums labeled as "rich" or "intense."

If your hair is color-treated, look for serums formulated for color-treated hair. These serums will protect your hair color from fading while providing the necessary nourishment.


Looking for the "for dry hair" label is a great place to start when selecting a hair serum. Take it a step further and learn which ingredients are most beneficial; look for some of these ingredients or other nourishing oils and butters when picking the right dry hair serum.

  • Argan oil: This natural oil contains antioxidants and fatty acids. It's very moisturizing and can improve the condition of dry hair.

  • Coconut oil: Another natural oil rich in fatty acids, coconut oil has moisturizing properties that protect the hair from damage.

  • Shea butter: It's natural and rich in fatty acids and vitamins. Shea butter's moisturizing properties smooth the hair shaft and reduce frizz.

  • Honey: This natural humectant attracts moisture to the hair. It's also antibacterial and protects the hair from damage.

  • Hydrolyzed proteins: These proteins are broken down into smaller molecules. They repair damaged hair to make it stronger and more resilient.
