You take caring for your complexion to the next level by incorporating serums and oils into your daily skincare regimen. But when it comes to levelling up your haircare routine with a hair serum, odds are you may shrug it off as an unnecessary additional step.
The truth is, hair serums – which are part of the leave-in conditioner category – are the do-it-all heroes in the hairstyling department. These formulas are mainly intended to help frizzy hair stay smooth under humid conditions (like the Singapore climate).
If you’ve always wanted to learn more about hair serums but you’re not quite sure which one is the best hair serum for you, keep reading to find out what hair serums are all about, plus our top recommendations of hair serums to try in Singapore.
What exactly is a hair serum?

Often made of silicones, hair serum is a styling product that’s designed to coat the hair’s surface to help impart added shine, smoothness, and hydration while offering humidity and pollution protection.
Recent technological advancements have of course enabled brands to create newer, better formulas so fret not, you always have the option to go silicone-free!
It’s easy to confuse hair serums with hair oils since both generally function to keep hair sleek and hydrated, but many hair serums now are created to address styling needs for different hair types (fine, medium or thick), help with hair damage or hair loss, or enhance texture (wavy, curly or straight).
Hair serums of the past also tend to get a bad rap for being too heavy and slick for fine, thin or oily hair types. However, you’ll no longer have this issue with most modern formulas as they’re all made to be lightweight and easy to apply.
Now, only some are intentionally made with more oils as these formulas are meant to be heavy-duty serums for thick, coarse or dry textures.
What’s more, hair serums can be used on wet or dry hair, and also act as both a pre-styling treatment and a finishing product, making it perfect for wash days, in-between washes, and on-the-go touch-ups.
Now that we’ve (hopefully) made the case for hair serums, check out our favourite hair serums ahead that you can easily get in Singapore to give your crowning glory the TLC it needs.
