Keeping hair smooth and sleek has always been an impossible task without some serious professional help in a humid climate like Singapore. One minute you’re in a room with blazing air-conditioning that dries out your hair (and skin), and the next minute you’re outdoors, exposed to the suffocating humidity and heat.
The thing about high humidity is, while it minimises trans-epidermal water loss from our skin, water molecules in the air become more than happy to penetrate hair shaft. And if your hair isn’t already in the pink of health, this causes the hair shaft to swell unevenly throughout, leaving you with frizzy hair.
This also means that to keep frizz and flyaways to a minimum, you must repair and protect your tresses by replenishing them with nutrients so that water molecules from the air is prevented from entering your hair shaft as much as possible.
Next, you should also choose products that smooth down hair cuticles: When these cuticles lie flat against one another, it becomes harder for water molecules to enter the hair shaft. As a result, your hair is healthy, glossy and no longer prone to damage. Here we have gathered the best smoothing serums that are suitable for all hair types and are under $30.
