Yes! You’re still missing out on one essential product – best hair serum!

Ask me what hair serum is, and I’ll confidently tell you it’s the one-stop solution to all your hair problems (Thanks Korea).

Hair serum is magic in a little bottle; there is no better way of putting it.

Coming with a high concentration of active ingredients, hair serum softens and protects the hair from aggressive environmental threats. Its multi-benefit makes it a must-have if you want to get the best out of your hair.

(You could use the table of contents below to jump to the sections that are most important to you.)

Benefits of Hair Serums

Hair serum doesn’t solve one, but multiple hair problems. And that’s why I refer to it as the one-stop solution for all hair woes.

A few drops of this magic will transform your bad hair day into a good one. You will feel and look different.

Here are a few of its benefits.

1. Protects the Hair

Hair serum forms a protective layer over your hair strands. The layer propels pollution, dirt, dust, heat, and solar damage.

This is why I advise using a heat-protecting serum before hot styling tools.

2. Suitable for Dry Hair

Men with dry and frizzy hair are the biggest beneficiaries of serums. Hair serums add moisture to the hair, making it smooth and shiny.

3. Adds a Shiny Glow

The protective layer formed by the serum also acts as a light reflector.

The result is a lustrous and shiny look. One ingredient of hair serums is amino acids that protect chemically treated and colored hair.

4. Prevents Hair Breakage

When our hair is entangled, we lose lots of hair strands detangling it. This is where hair serum comes in. It acts as a lubricant and makes the detangling process easy.

5. Nourishes the Hair and Makes it Manageable

Hair serum works by filling the follicular cracks and reviving damaged hair. This makes the hair more manageable and easy to style. Save yourself from the hassle of battling entangled damaged hair.

6. Great for Parties

If you want to be the center of attraction at parties, one sure way is to have incredible hair. Hair serum will give you shiny, lustrous hair making you a head-turner at all events.

What of Its Disadvantages?

I don’t want to ruin the party, but there are a few disadvantages associated with hair serum.

  1. Applying hair serum can be a little tricky. Precaution is needed to ensure nothing goes wrong.
  2. Too much hair serum can make your hair excessively oily. You should avoid over-depending on it.
  3. Hair serums that contain silicon as an ingredient might lead to hair fall.

Top 5 Best Hair Serums For Men – Reviews & Top Picks

What are the best hair serums in the market? My long search ended up with these five products. There must be something special about them.

1. Herstyler Hair Repair Serum

Herstyler Hair Repair Serum Review

Herstyler Hair Repair Serum has withstood the test of time and remains to be one of the best serums out there – And for good reasons. The company is known to combine its high-end hair enhancing products with the latest technology.

This gives them the edge over their competitors. They are innovative and always up to date.

What you’re settling for with this serum is an instant makeover, ultra-nourishing treatment for your frizzy hair. Only a few products could combat a bad hair day better than this. It will nourish, moisturize, and improve your hair’s luster.

How do you use the serum?

Apply two or three of its drops to your hair then work it in slow, gentle movements. The formula will repair dry and brittle ends, not to mention reviving dull and damaged hair. It will reduce the tangles, frizz, and split ends present in your hair.

The goodies don’t end there. This product is also highly affordable (the second cheapest on my list). I had to counter-check the price to be sure. You now see why I consider it the best. No product will provide you better value for your money than this.

The only issue with the serum is that some testers found its scent to be a little conk. But who cares when you can use hair perfumes for better hair fragrance?

It’s not every day you land a perfect deal like what you’re getting with the Herstyler Hair Repair Serum. Make the most out of it!


  • Highly affordable
  • Reduces the frizziness and tangles in the hair
  • Makes hair glow


  • Slightly conk scent

2. Biotin Hair Growth Serum

Biotin Hair Growth Serum Review

Who doesn’t love beautiful hair? You can now fulfill your dream of having fuller, thicker, and healthy hair with the Biotin Hair Growth Serum.

The second product on my list does more than just nourish your hair. It contains premium ingredients that strengthen the hair’s roots for thicker and healthier hair growth.

This serum has active ingredients consisting of Pisum Sativa Pea Sprout, which moisturizes the hair and gives it a soft, healthy texture. The icing on the cake is that the product works with all hair types. Be it short or long, blonde or brunette, curly or soft, its advanced formula will bring out the best in your hair.

The secret to this serum’s success lies with its ingredients. The company doesn’t believe in cutting corners. That’s why they use nothing but the finest, natural ingredients for the product.

When applying this serum, allow some time for the serum to absorb fully. Don’t blow-dry it right away. Also, use the serum daily and at night for maximum results.

Are there any downsides to it?

As much as I would have loved for this product to be perfect, it isn’t. If your hair isn’t washable daily, then using this serum will be a problem for you.

Remember, it is designed to be used daily for maximum results. This also implies that you’ll be washing your hair daily.


  • Results in thicker, longer, and healthier hair
  • Is of premium quality
  • Highly affordable


  • Not suitable for hair that shouldn’t be washed daily

3. Ultrax Labs Hair Plush

Ultrax Labs Hair Plush Review

Like Biotin Hair Growth Serum, Ultrax Labs Hair Plush is a premium quality serum designed to bring the best out of your hair. Everything with this product lies in its top synergistic ingredients.

A lot of study and research was done before coming up with this product’s formula. Well, all that hassle was worth it as the result is astounding. Its three main ingredients are hydrolyzed keratin, biotin, and caffeine.

Keratin revitalizes the hair, restores its elasticity, and reduces breakage. It reduces hair damage caused by harsh chemicals. The ingredient also coats the hair shaft for noticeably thicker hair.

Biotin, on the other hand, works to strengthen the hair follicle for long, lush hair. Strong hair allows each strand to reach its end growth cycle.

Caffeine is a controversial ingredient. Studies have shown that the powerful ingredient can stimulate hair follicles’ life cycle, thus encouraging hair growth. When the three ingredients combine, nothing will stop them.

The only issue with this serum is that its price is exaggerated, considering it only lasts you one week. There is no balance between amount and price, giving you no value for your money. But if you’re desperate for quick positive results, this shouldn’t be a biggie.


  • Quick results
  • Reduces hair breakage and restores its elasticity
  • Uses powerful ingredients


  • Expensive
  • The serum will only last you one week.

4. Genius Stem Biotin Hair Growth Oil

GENIUS Hair Growth Oil Review

The packaging of the Genius Hair Growth Oil is one to intimidate. The black and yellow combination of its box and bottle makes it look more like a lab chemical than hair serum. But that’s what to expect from a product as powerful as this serum.

Don’t get me wrong; this serum is safe and gentle on the hair. It lacks paraben, gluten, and sulfate, among other harsh chemicals. It is also non-scented for those who despise strong fragrances in their serums.

The ingredients of this serum promote the rapid growth and nourishment of hair. They do so by activating the dormant follicle germ tissue on the scalp. The formula also thickens thin hair and eliminates frizzes and breakage.

This property makes the serum excellent for men with hair loss or baldness.

When applying this serum, add two or three of its drop with shampoo then massage it into your hair. Work from the roots to the tip of the hair using your fingertips. When done, wash it thoroughly with warm water.

Any downsides?

You’ll spend double on this serum than what you would’ve on the Herstyler Hair Repair Serum. Think about it.


  • Non-scented
  • Paraben, sulfate, and gluten-free
  • Promotes rapid growth of hair


  • Slightly expensive

5. John Frieda Hair Serum

John Frieda Hair Serum Review

John Frieda Serum protects your hair from heat damage and weather-induced frizz. Its formula that consists of bamboo extract will transform your dry, frizzy hair to a moisturized one.

But there’s more to its function. The serum repels humidity, smoothen strands, prevents heat styling damage, tames flyaways, and hydrates hair.

In short, there’s nothing that this serum cannot combat. And the good thing is that it does all this at an amazingly affordable price.

This serum is the cheapest on my list. So if you are tight on budget but still want an effective serum to protect your hair, no option could be better.

When applying this serum, apply a drop into your palm then rub it gently around your hair. Do so while avoiding the roots. You can increase the amount depending on your hair’s length and thickness. Unlike other serums, don’t rinse it out. Instead, style your hair to your liking.

You couldn’t be prouder of your hair serum.


  • Excellent for when you’re styling your hair
  • Very cheap
  • Nourishes the hair and gives it a smooth texture


  • The purchase might come with errors.

How Do You Choose the Right Hair Serum?

1. Hair Type

What type of hair do you have?

That should be the first thing to take into account when purchasing a hair serum. Knowing your hair type will assist you to get the best results from your serum. There are serums for different hair types:

Chronically Dry Hair

Excessively dry hair requires nutrition and extra care. The good news is that manufacturers designed hair serums for such hairs that you can apply overnight. Such serums are cream-based and not oily so as to avoid weighing down the hair instead of moisturizing it.

Applying these serums to dry and damp hair will make them shiny and nourished in the morning.

Thick and Textured Hair

Thick hair requires a hard-working product that provides it with extra hydration. There are hair serums specifically for this purpose. Such serums contain Moroccan and argan oils as their main ingredients.

Split-end Rid Hair

Split ends make hair prone to breakage. That’s why you must use serum to improve its appearance. Hair serum for split-end hair contains keratin as its main ingredient. Keratin is popular for preventing hair strands from splitting.

Colored Hair

You don’t want to apply a product to your colored hair only for it to bleach to another color. For this reason, the market has serums specifically for colored hair. These serums are lightweight and cream-based and contain coconut, argan, and jojoba oils as their main ingredients.

Curly Hair

Curly hairs get frizzy and become difficult to manage. These hairs require serums with intense moisturizing properties.

2. Ingredients

There are two important aspects of serums when it comes to ingredients.

First, ensure that the ingredients used should match the intended purpose of the serum. For instance, hair serum for split-end hair must contain keratin whereas that of colored hair should have jojoba, coconut, or argan oil.

Secondly, ensure that the product you’re settling for doesn’t contain any synthetic or harmful agents. Such ingredients can be toxic for the hair and body. Avoid phthalates and paragons which are known to cause allergic reactions.

3. Needs

Why are you buying hair serum?

Is it for your split-end hair or thick and textured hair?

The hair type plays a major role when it comes to your need. Having this information will assist you to purchase a product that will give you the best results.

How to Apply Hair Serum?

Are you loving the idea of hair serums but aren’t sure how to add them to your daily hair routine? I have broken down the application process into five simple steps. You can now benefit fully from your hair products without making rookie mistakes.

  1. Use your serum on damp hair – not soaked (dripping wet) hair but damp hair.
  2. Flip your hair to the front.
  3. Add a few drops of the serum to your hand. Blot it between your palms to heat it up
  4. Start applying from the end, moving upwards towards the scalp.
  5. When done, brush your hair to get the desired effect.

Here is a video further illustrating how to apply hair serum (source).

Precautions to Take While Applying Serum [Pro Tips]

Here are a few things to keep in mind when using hair serum

  1. Be aware of your hair type and hair problem before using hair serum. You can always consult professional assistance if you aren’t sure. It will save you from landing the wrong product and worsening your situation.
  2. Avoid using fingertips when applying your serum.
  3. Don’t use hair serum on the hair roots as it will lead to buildup.
  4. Shampoo your hair before using a serum.
  5. Blow-dry your hair after applying a serum.
  6. Don’t rub the serum in between your palms (like what you do with oil. Instead, blot it gently.

Be cautious with the serum amount that you’re using. Excess serum can make your scalp greasy. Use one to two drops for medium length hair, and three to four drops for long hair.

Frequently Asked Questions

Which hair serum is best for my hair?

There are three different types of hairs: dry, oily, and combination. Other hair types lie in these three categories.

Choose a hair serum that is best suited for your hair needs. Cross-check with my list on the different hair types and their needs.

What are the different types of hair serums?

There are two main types of hair serums.

Serum for repair and nourishment: these serums are formulated to repair damaged hair and bring life to hair that’s exposed to lots of heat.

Serum for aesthetic purposes: The main objective of these serums is to improve the appearance of hair. The serums tame curls and reduce frizz in hair.

What does hair serum protect against?

The main functions of hair serum are to hydrate, shine, and reduce frizz in the hair. However, the hair product is also used to protect hair against external harmful agents.

Such agents include:

Dyes: Dyes and bleaches are harmful to the hair.
Heat styling: tools like curlers and straighteners expose the hair to extremely high temperatures. Hair isn’t meant to withstand such heat. Hair serum creates a barrier to protect the hair from this heat.
Solar radiation: solar is great for Vitamin D, although UV rays can prove harmful to the hair. Hair serum chips in and acts as a protective barrier.

Final Thoughts

Two things sum up the products on my list: incredible performance and value for money. Even though you’ll have to spend a little more on others, they’re worth the extra cost.

Note that different serums have different application methods. Some will require you to mix them with shampoos while others are to be used solely alone. Some are to be applied immediately, while others require some blending period. Some are to be rinsed off with warm water, while others only require styling.

Always counter check with the manufacturer’s instructions before using your product.

Which is the best product on my list? This is a tough one, but after much deliberation, the Biotin Hair Growth Serum won my heart. A huge reason for this was its affordability.

But if you’re tight on budget and still want a relatively good product, the John Frieda Serum is your go-to product. This, however, isn’t to dispute the rest of the products as of lesser quality. 

Bring out the best of your hair with these five incredible hair serums.
