Hair Serum

Hair serum is a lightweight, oil-based product that you apply to the hair to provide a variety of benefits, such as:

  • Protection from heat styling damage

  • Moisture and shine

  • Frizz control

  • Split end repair

  • Hair growth stimulation

Hair serums typically contain a blend of oils, silicones, and other ingredients to penetrate the hair shaft and coat the hair cuticle. This helps to protect the hair from damage, seal in moisture, and make the hair look and feel smoother and shinier.

How Does It Work?

The specific way that hair serum works depends on its ingredients. However, in general, hair serums work by:

  • Coating the hair cuticle to protect it from damage

  • Sealing in moisture to prevent dryness and frizz

  • Providing nutrients to the hair shaft to promote growth and repair

Importance of Hair Serum

Hair serum provides so many benefits to your hair! In addition to making your hair smoother, more manageable, and moisturized, it benefits your hair in several ways.

Hair serum protects your hair from the heat of styling tools, such as blow dryers, straighteners, and curling irons. It also protects your hair from the harmful UV rays of the sun, the same way sunblock shields your skin. This protection prevents damage to the hair shaft and reduces the risk of split ends.

Moisture and Shine

Hair serum adds moisture to the hair and makes it look and feel smoother and shinier. This is especially beneficial for dry, damaged hair.

Frizz Control

Hair serum controls frizz and flyaways. It coats the hair cuticle to smooth out hair strands and allows the hair to retain moisture, even in humid climates.

Split End Repair

Hair serum provides nutrients to the hair shaft and helps seal the cuticle, potentially repairing split ends.

Hair Growth Stimulation

Some hair serums contain ingredients that appear to stimulate hair growth. However, more research is needed to confirm the effectiveness of these ingredients.

Types of Hair Serum

Come one, come all! There's a hair serum (or four) that can benefit everyone. Are you looking to control your frizz, protect your hair from the heat of styling tools, or promote hair growth? Find the right kind of serum for your needs.

Heat Protectant Serum

Heat protectant serums work by coating the hair shaft with a layer of silicone or oil. This layer reflects heat away from the hair, protecting it from damage. Heat protectant serums are especially important for people who use heat styling tools on their hair regularly or spend time in the sun.

Moisturizing Serum

Moisturizing serums use oils, butters, or humectants that attract water to the hair. They prevent dry, damaged hair while making the hair look and feel smoother and shinier. Anyone who doesn't struggle with greasy hair could benefit from a moisturizing serum.

Frizz Control Serum

Frizz control serums coat the hair shaft with a layer of silicone or oil. This layer helps to smooth out the hair strands and reduce frizz. Frizz control serums are especially helpful for people with curly or wavy hair — or anyone who has a poodle look they can't contain!

Split-End Repair Serum

Split-end repair serums fill in gaps in the hair shaft. They typically contain proteins or amino acids that strengthen the hair and prevent split ends from forming. Split-end repair serums improve the overall appearance of the hair and make it look smoother and healthier.

Volumizing Serums

Add some body to your hair with a volumizing serum. These products contain lightweight ingredients that don't weigh down the hair but give a fuller, more voluminous appearance. If you struggle with flat hair, try one of these serums to bring some life back to your look.

Color Protectant Serum

Protect your hair color from fading with a protectant serum. These serums contain antioxidants to neutralize free radicals that damage the hair color. If you color your hair or have color still lingering on your strands, these products are necessary in your hair routine!

Anti-Dandruff Serum

Anti-dandruff serums kill the fungus that causes dandruff. They typically contain ingredients such as zinc pyrithione or selenium sulfide. If you struggle with dandruff flakes or an itchy scalp, use an anti-dandruff serum to help your scalp recover.

Hair Growth Serum

Stimulate your hair follicles to recover balding spots or thicken your hair with a hair growth serum. These products contain ingredients such as minoxidil or finasteride to stimulate the follicles. Promote hair growth and prevent more hair loss with the proper serum, such as The Ordinary Hair Serum or Divi Hair Serum.

The founder and CEO of the popular haircare brand Ceremonia, Babba Rivera, says, "Scalp health is hair wealth! Customers are becoming more interested in the care and wellness aspect of haircare and are starting to connect the dots that healthy hair and growth ultimately begin at the scalp. I anticipate more demand for scalp scrubs, scalp serums, and oils to combat itchiness, remove buildup, and accelerate hair growth."

Stay ahead of the latest products in hair care by getting a serum that promotes a healthy scalp and hair growth! In August 2023, experts recommended a scalp massager to stimulate the follicles.

Choosing the Right Product

There's a hair serum out there for everyone, but you must make an informed decision to ensure you find the results you're dreaming of. Consider these factors on your journey to perfect hair.

Your Hair Type

There are different formulas for different hair types, so carefully choose one that's right for your hair.

Dry Hair

Dry hair needs moisture, so look for a serum that contains moisturizing ingredients, such as argan oil, jojoba oil, or shea butter. Avoid serums that contain alcohol, as it can dry out your hair.

Fine Hair

Fine hair requires a lightweight serum to avoid weighing it down. Find a serum that's oil-free or has a light oil base.

Thick Hair

Thick hair can handle a heavier serum. Look for a product with proteins or amino acids to help strengthen your luscious locks.

Curly Hair

Curly hair is prone to frizz. Select a serum that contains a frizz control ingredient, such as silicone or argan oil.

Color-treated Hair

Color-treated hair benefits from a serum that protects the color from fading. Invest in a serum that contains antioxidants, such as vitamin E or grapeseed extract.

Damaged Hair

Damaged hair needs a serum that'll help to repair the damage. Look for a serum that contains keratin or other proteins to assist you on your hair-healing journey.

Your Hair Concerns

There are hair serums to address any of your hair concerns: frizz, split ends, thinning, and more. Choose a serum to align with your goals:

  • If you need some frizz control, look for a serum containing a frizz-control ingredient, such as silicone or argan oil. These ingredients smooth out the hair strands, lock in moisture, and reduce frizz.

  • For split-end repair, look for a serum that contains proteins or amino acids to fill in the gaps in the hair shaft and prevent split ends from forming.

  • If you're looking to promote hair growth, look for a serum that contains ingredients such as minoxidil or finasteride.

  • If you have colored hair, look for a serum that contains antioxidants for color protection.

  • Repair damaged hair with a serum that contains keratin or other proteins. These ingredients repair damage while making your hair stronger and healthier.

The Ingredients

Choose a hair serum based on its nutritious ingredients. Most hair serums contain a combination of these ingredients (and beware of anything that you're sensitive to).

Argan Oil

Argan oil is rich in antioxidants and fatty acids. This natural oil moisturizes the hair, protects it from damage, and improves shine.

Jojoba Oil

Jojoba oil is a natural oil, similar to the natural sebum produced by the scalp. It hydrates the hair and scalp while preventing dryness and dandruff.


Keratin is a protein and the main component of hair. Hair serums with keratin repair damaged hair to make it stronger and healthier.

Vitamin E

Vitamin E is an antioxidant that protects hair from damage. It also moisturizes and improves shine.

The Price

Hair serums can range in price from a few dollars to over 100 dollars. Choose a serum that fits your budget and needs. You often get the quality you pay for, but there are certainly affordable options that will work wonders for your mane!

How To Apply

Apply hair serum once or twice a day, and sometimes more if your hair is very dry or damaged. Use this routine every time you wash your hair:

  1. Wash your hair with a shampoo and conditioner that's appropriate for your hair type.

  2. Rinse your hair thoroughly with warm water.

  3. Apply a small amount of hair serum to your hands.

  4. Rub your hands together to warm up the serum.

  5. Apply the serum to your hair, starting from the ends and working your way up to the roots.

  6. Be sure to evenly distribute the serum throughout your hair, delicately using your fingers to spread it through.

  7. Style your hair as desired, including with other products you typically use, such as leave-in conditioner or mousse.

Tips To Avoid Common Mistakes

Although the magic of hair serum is clear, you still need to use it properly to reap the benefits. Follow some of these tips to avoid common mistakes:

  • If you wet your hair without washing it, reapply serum to protect your hair and give it an extra boost of moisture.

  • You can apply hair serum to dry hair, but distribute it into your ends and mid-shaft, avoiding your scalp. Use less when your hair is dry, as it's more difficult to distribute.

  • Avoid using too much serum and weighing your hair down. Start with a little, and apply more if needed.

  • Many people apply too much serum to the scalp when they start using these products. Begin at the tips, the most vulnerable part of your hair, and thoroughly distribute it, using whatever is left over for the roots.

  • Don't use heat immediately after applying serum — give your hair a few minutes to absorb the magic stuff. Remember to protect your hair from the UV rays of the sun, too!

  • It's common to buy the wrong type of serum for your hair. Use this guide to figure out exactly what you need, and thoroughly read products before purchasing them.

  • Are you a culprit for ignoring beauty product expiration dates? Pay attention to how long your serum is good for, and replace it when it expires.

  • Make sure you apply your serum regularly to properly care for your hair — that means every day!
