Did you know your hair care routine can go beyond just using shampoo and conditioner? You can add hair serums to target specific hair woes and fix them at the root — pun intended — cause.
Why you need a hair serum
A hair serum acts as a leave-on hair treatment with a higher dose of active ingredients.
Similar to skincare serums, hair serum is a more concentrated version of your hair care products. This means you get a higher dose of the active ingredients that will help solve your hair problems. It's extremely beneficial if you deal with hair loss or scalp congestion, as these need leave-on solutions to be corrected. You can see why wash-off products, like shampoos, conditioners, and masks may not be as effective.
Now that you know why your mane needs a serum, here are the best hair serums you can get in Singapore.
