Is Hair Serum Essential? Uncover Its Role in Haircare


Those gleaming locks on glossy magazine covers and the polished strands flaunting on Instagram are not just a product of good lighting. Behind every lustrous hair picture is the magic of a good hair serum. Let's untangle the facts and demystify what good a hair serum can truly do for your hair.

What is a hair serum?

Hair serum is a liquid-based treatment characterised by its light, slightly thick consistency. Unlike heavy oils and creams, hair serums have a clear to slightly tinted appearance and a silky texture. The non-greasy nature ensures smooth application, making it distinct from other hair care products.

What does a hair serum do?

Hair serums are known for their quality of making hair manageable. Let’s explore all the other wonderful benefits:

  1. At the core of hair serum benefits is its power to ward off frizz. With just a few drops, they lock in moisture, ensuring humidity doesn't spell disaster for your hair.
  2. Hair serums are synonymous with shine. Their light-reflecting properties bestow a healthy glow to your hair, making every strand look revitalised.
  3. Think of hair serum as a protective shield for your hair against external aggressors like the sun, pollution, and environmental damage.
  4. Many serums offer a protective barrier against heat, ensuring that your hair isn’t damaged when you use styling tools like straighteners or curling irons.
  5. When pondering over how to use hair serum for shiny hair, remember it's an excellent smoothening agent. It aligns hair cuticles for a sleek finish. Moreover, if you’re struggling with knots, hair serums can be your saviour, making combing easier and reducing breakage.
  6. Serums provide that extra dose of hydration, making them perfect for dry and lifeless hair. They're not a substitute for conditioners but are a great addition.

Do you need a hair serum?


Absolutely! Every hair type, whether straight, wavy, or curly, can benefit from a hair serum. It acts as an armour against daily stressors, making it a must-have hair serum for daily use. From imparting shine to straight hair to defining curls, its benefits are manifold. With rising pollution and frequent heat styling, it's not an indulgence but a necessity.

Your simple 3-step hair care routine


If you’re wondering how to apply hair serum or how to incorporate it in your current routine, here’s a detailed guide:

  1. Cleanse: Start with a deep cleanse using a suitable shampoo. A proper cleanse rids hair of dirt and preps it for further treatment.
  2. Condition: Hydrate with a conditioner or a mask. Ensure it penetrates the hair shafts for maximum benefits. Focus on mid-lengths and ends.
  3. Protect and Shine: The final yet pivotal step revolves around protection and enhancement. And this is where our Elixir Ultime L'Huile Originale Serum shines brightly. This hair serum is suitable for all hair types and provides a protective barrier against external damages such as heat, pollution, and UV rays. Its regular use ensures that your hair remains resilient and looks salon-fresh, day in and day out.

Here’s how to use the Kérastase hair serum:

  1. Step 1: Apply 1-2 pumps of the leave-in hair serum on damp or dry hair. Start from mid-lengths and work to ends.
  2. Step 2: Style your hair as desired after using the serum of your choice.

If the next thought in your head is, ‘How often should I use a hair serum?’ the good news is that you can use this nourishing, lightweight leave-in hair serum every day. Incorporating these three steps into your daily routine ensures a holistic approach to hair care. While each step has its unique benefits, together they form a synergistic trifecta, ensuring your hair remains at its healthiest, most radiant best.

In conclusion, hair serums aren’t just another product to add to your shelf; they are game-changer in your hair care routine. Their ability to protect, nourish, and transform the texture of your hair is unparalleled. Whether you're battling frizz, seeking shine, or just wanting to give your hair an added layer of protection, a hair serum steps up to the task.
