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.
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.

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.
