Tame Your Mane With These 9 Best Hair Serums

Messy hair, don’t care? Let’s be real—we care a lot! We’re always on the lookout for beauty products that help us achieve that effortless, low-maintenance look without the hassle. If you’ve ever wished for smooth, shiny hair that doesn’t require a salon visit, hair serums are your secret weapon. After testing a variety of options, I’ve rounded up the 9 best hair serums in Singapore that cater to different needs and hair types. 

What is hair serum?

Hair serums are concentrated, lightweight treatments designed to improve the health and appearance of your hair. Unlike regular conditioners or hair oils, hair serums are formulated with a blend of active ingredients that target specific hair concerns. They typically come in a liquid or gel form and are meant to be applied after washing your hair or whenever you need a touch-up.

Best hair growth serums to combat hair loss

1. The Ordinary Multi-Peptide Serum for Hair Density 

After hearing a lot of buzz about The Ordinary’s Multi-Peptide Serum for Hair Density, I decided to give it a go, and I’m glad I did! Upon opening the bottle, I was pleasantly surprised by the lightweight texture. It’s not greasy at all, which is a major plus for me. I appreciate that it feels more like a hair treatment than an oil, making it easy to apply without weighing my hair down. 

The hair serum has a subtle, almost neutral scent that isn’t too much — just fresh enough to feel rejuvenating. I loved that it absorbed quickly, so I didn’t have to wait long before styling my hair. After using it consistently for about a month, my hair felt thicker, and there was a noticeable reduction in hair fall. I even received compliments on how full my hair looked! The Ordinary hair serum definitely lives up to its claims of promoting hair density.

2. Pilgrim Hair Growth Serum

I also had my sister try the Pilgrim Hair Growth Serum as she’s been struggling with thinning hair for some time now. The non-greasy, water-based formula not only seemed promising but also offered the convenience of quick absorption, ensuring that she wouldn’t have to deal with any sticky residue or any oily feel after. It was important to her that her scalp felt comfortable without the need for an extra shampooing step afterwards, making it easy to incorporate into her routine.

With key ingredients like redensyl for promoting hair growth, anagain and zinc for strengthening, and green tea extract for scalp health, this best hair serum in Singapore delivers impressive benefits. After about four weeks of consistent use, she noticed a significant improvement in her hair’s texture and volume, along with reduced hair fall in the shower. These positive changes gave her the confidence to continue using this hair growth serum as part of her hair care regimen.

3. KERASTASE Resistance Serum Extentioniste

What’s next on my must-try list is the KERASTASE Resistance Serum Extentioniste! It’s designed to stimulate and protect the scalp while promoting healthier, longer hair.

4. John Frieda Frizz Ease All-in-1 Original Serum 

The John Frieda Frizz Ease All-In-1 Original Serum is often hailed as one of the best hair serums for dry hair in Singapore, and I was excited to see if it lived up to the hype. This John Frieda serum tackles frizz while providing heat and humidity protection, all while adding a beautiful shine.

5. FINO Premium Touch Hair Serum

The FINO Premium Touch Hair Treatment Oil is the latest TikTok trend I couldn’t resist trying! This daily leave-in oil is designed for flat, dry, or frizzy hair, promising long-lasting airy smoothness and shine. This FINO hair oil features a combination of powerful ingredients like squalane, amodimethicone, and hydrolysed conchiolin, which work together to repair and nourish damaged strands. Its damage sensor function helps to intensively repair each strand, resulting in smooth and glossy hair. Furthermore, the lightweight, non-sticky formula coats the outer layer of hair, reducing frizz too.

For optimal results, I used this best hair serum in Singapore with the FINO hair mask. I found that applying 1-2 pumps on towel-dried hair gave a soft, voluminous finish, while a few drops on dry hair provided that extra shine and smoothness.

I first discovered UNOVE Water Essence Hair Mist during a recent trip to Korea, where it was proudly displayed on the number one bestseller shelves at Olive Young. Intrigued by its popularity, I decided to buy one just for fun and wow was I amazed by the results.

This hair mist creates a moisturising film on dry hair, effectively hydrating and revitalising each strand.
