The secret to nutritious and flawless hair is using the best hair care products. Besides taking the perfect shampoo, deep conditioning, and comb-drying your hair, the best hair serum is the trump card to ward off your hair concerns. Be it hair loss, brittle hair, or frizz, hair serum is one of the essential hair treatment steps you cannot skip.
Going for the right pick of hair serum is not going to disappoint you. We have collected outstanding hair serums for every hair type to cater to your specific hair concerns. Before we go into details, let’s find out what is the usefulness of adding a hair serum to your routine.
Why is Hair Serum so Important?
Hair serum goes beyond your basic hair care. From enhancing hair growth to repairing breakage, the serum is a real Holy Grail to restore your hair health. Hair serum can benefit your hair in different ways depending on the type of hair serum you take.
Here’s what hair serum can do:
Protects against damage
Hair serum is a leave-in treatment, meaning it will coat your hair for some time before you rinse it. At that time, the serum helps to protect and even repair your hair effectively from damages caused by:
- Environmental factors like UV exposure,
- Heat damage from flat iron or hair dryer, and
- Chemical processes like bleaching, coloring, relaxing, or perming.
You can choose a hair serum that acts as a heat protectant, which you have to apply before using hot tools or pick a serum for chemically-treated or damaged hair.
Control frizz
Hair serum contains silicone that can help to reduce frizz and dryness caused by weak and damaged strands. Silicone adds substance to weak and porous strands, making it beneficial to control frizz. It also can define the curls and waves of your hair.
Boosts smoothness and shine
Besides reducing frizz, silicone is beneficial to soften your hair, making it shinier than ever before. Some types of silicone may reflect light, which will improve the shine and sleek appearance of your hair.
Reduces tangles
Conditioners may do this job in the shower, but hair serum will double the effectiveness with its detangling effect. It leaves your hair sleek and smooth, making it easier to comb and more manageable.
Now you know the benefits of hair serum, let’s take a closer look at what to consider before investing in hair serum.
How to Choose the Right Hair Serum
When it comes to hair serum, what you will pick depends on what your hair and scalp need. Buying the right hair serum that fits your hair condition may do wonders. Below are how to choose a hair serum for you:
Hair type and ingredients
A silicone-based hair serum may be the best choice to tame frizz and detangle, and picking the right one that compliments your hair type is very helpful. Here are the hair-loving ingredients based on your hair type:
- Dry and frizzy hair should look for a hair serum that contains silicone. It acts as an occlusive which blocks water evaporation and keeps hair more hydrated. Since silicone only sits on top of your strands, kindly wash your hair thoroughly after applying this type of serum.
- Color-treated hair needs intense hydration, which should consider a hair serum with a nourishing oil (jojoba oil, almond oil, argan oil), chemical-free ingredients, and cream-based formulas.
- Curly hair loves hydrating ingredients that keep the curls stay intact and bouncy, be it baobab seed oil, jojoba oil, or avocado oil.
Frequency of use
Lightweight serum can be used as a daily routine to protect your hair against damage from environmental stressors or heat styling tools. Thicker and oilier hair serum should be applied once or twice a week for deep nourishment and repair. Read the instructions given carefully to ensure the frequency of use and the recommended amount.
Pick an alcohol-free hair serum
It’s best to avoid using hair serums that contain alcohol as these can dry out your hair, which is the opposite of what you’re trying to achieve with serums. Choose a serum that is rich in natural oils to restore your hair integrity and health. Now, let’s check our best hair serums to nourish your hair.
