11 Of The Best Hair Serums & Why You Need To Try One

Do you use a serum for your hair? A hair serum is often times overlooked (skipped) but it’s like adding a protective shield for your hair. A conditioner isn’t always enough, especially if you use hot styling tools, work out a lot or expose your hair to sun and salt water. So I’m making the argument that you also need a serum. It will protect your hair from these harmful elements and infuse it with hydration too.

Why You Need A Hair Serum

Hair serums are formulated to increase the volume of hair and fill it out. Some ingredients, such as hydrolyzed silk and hyaluronic acid, provide nutrients and hydrate the hair, which helps your hair appear more full by making it more pliable. And as we age, who doesn’t want thicker hair?

The Best Hair Serums

There are now dozens of hair serums on the market, so how do you find the best one for your hair needs? Well I have tested a bunch for all different hair issues, but admittedly my favorites are the ones for “anti-aging” and hair growth. And I know, those are the ones I know you are most interested in anyway. Don’t worry, I found some budget friendly hair serums too.

Here are my 11 hair serum picks (in no particular order):

1. Grande Cosmetics GrandeHAIR Enhancing Serum, $55

Grande Cosmetics makes a fantastic lash growth serum so of course I had to try their hair serum. This cruelty-free serum is formulated with vitamins, peptides and amino acids. It contains Procapil™ which helps to fortify and anchor hair for a fuller, thicker appearance over time. Gingko Biloba is an antioxidant that helps to stimulate the scalp while flower extracts help to improve the condition of the scalp.

2. Elvive Hyaluron + Plump Moisture Plump Serum, $6.97

This paraben-free daily leave-in serum delivers a boost of moisture, replumping and reshaping for dry, dehydrated hair. It’s infused with a 2% Hyaluronic Care Complex for 2x hydration and replenished moisture. It also smells amazing. 

3. Briogeo Destined for Density™ Peptide Hair Serum for Thicker, Fuller Hair, $57

If you have thinning hair, you are going to want to try this concentrated leave-in daily serum. It’s clinically shown to increase hair density by up to 3x. It contains Briogeo™ NOVA Complex which helps stimulate the scalp and strengthen hair to promote hair density for any hair type or texture, or if you are experiencing or concerned with thinning hair, excess shedding or loss of density. It also contains caffeine, CoQ10, biotin and copper peptides. With consistent use, the serum is shown to increase density by up to 220%, compared to baseline in a 16-wk study of 35 participants. Oh and it’s vegan, gluten-free, cruelty-free, and comes in recyclable packaging. Sweet.

4. Olaplex No. 9 Bond Protector Nourishing Hair Serum, $30

Of course an Olaplex product made the cut! This serum does it all. It hydrates, protects and adds shine for all hair types. Just use a tiny bit on damp or dry hair and your hair will feel silkier instantly. This silicone-free formula will leave your hair shiny, soft and you’ll be totally in love with your hair again. Used on dry hair it tames flyaways too. It’s amazing.

5. Hush & Hush Deeply Rooted Hair Serum, $75

If you have sensitive skin you will covet this hair serum that helps calm scalp irritation, redness, itching and flaking. This lightweight, stimulating leave-in serum rejuvenates the hair with clean, plant-based ingredients that enrich and nourish the scalp for reduced shedding and optimum hair health. It’s clinically-proven to revitalize aging and thinning hair. It improves follicle regeneration. Massage directly into the scalp and sleep with it every night for optimum results.

6. The Ordinary Multi-Peptide Serum For Hair Density, $15

How can you not love products from The Ordinary? They deliver and are affordable. Case in point? Their Multi-Peptide Serum for only $13! If you seek thicker, fuller, denser and healthier hair then you need to get The Ordinary hair serum that encourages hair regrowth. Apply it to your scalp before bed every night and wake up to fuller hair in just a few months. I also applied some to my brows. Can’t hurt. It’s made without fragrance, sulfates or mineral oil.

7. Garnier Fructis Sleek & Shine Anti-Frizz Serum, $5.99

Garnier’s Sleek & Shine serum proves a great hair day doesn’t have to cost you a ton. It’s blend of argan and apricot oils will provide a smooth finish for all hair types. And it’s under $6!

It combines pea peptides, Amla, and a combination of plant extracts to revitalize and rejuvenate hair, leaving strands fuller, stronger and shinier. It also includes the brand’s hero ingredient, ectoine. This genius ingredient uses smart-targeted hydration to distribute intense moisture where it’s needed most.

9. Alterna Haircare Styled CAVIAR Anti-Aging® Restructuring Bond Repair 3-in-1 Sealing Serum, $38

This 3-in-1 serum repairs, protects and seals in one step and can be used on any hair type. It strengthens, protects and adds resiliency to damaged strands after one use. Using their exclusive Caviar Bond Enforcing Technology, it fills cracks and fissures in the hair’s external structure while smoothing and adding moisture and shine to depleted strands.

10. Dr. Barbara Sturm Super Anti-Aging Scalp Serum, $100

Yes, it costs a bit more, but isn’t your hair is worth it? This serum is an ingredient science-rich treatment especially formulated to boost shine, suppleness and volume in aging hair. It contains candle bush, sand oat, purslane, hyaluronic acid and thorny knapweed antioxidant-rich plant extracts that help strengthen the scalp. Pro-Vitamin B5 helps nourish and provide resiliency to the hair shaft and helps hair to not split.
