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 the length, so its wiry appearance ends up looking like 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 less water molecules from the air enters your hair shaft in the first place. Next, you should also choose products that smooth hair cuticles: When they lie flat against one another, it becomes harder for water molecules to enter the hair shaft. Another benefit? Shine and resilience are also restored so your hair is healthy, glossy and no longer prone to damage. Here, the best smoothing serums that are suitable for all hair types, under the price of $30:
