Inside Argan Oil Hair Serum – Ingredients Breakdown

As its name suggests, this nourishing serum harnesses the multi-purposed Argan Oil that delivers a shiny, frizz-free finish to your hair. Below we display a full list of the ingredients in the product:
Now, we’ll take a closer look at their key ingredients and how each impacts your hair health.
Silicones (as Cyclopentasiloxane, Cyclohexasiloxane, and Dimethicone)
These substances are at the top of the ingredients list, so it’s safe to say that HerStyler Argan Oil is basically a silicone-based serum.

Silicone can coat your hair shaft, which locks in moisture and tames frizz. Eventually, it improves your hair textures, leaving a silky, soft feel. Silicone is very helpful for people whose hair could not tolerate humidity well.
However, silicone also has some downsides. For instance, long-term use of silicone can build up on your hair, leading to stripping your hair’s moisture and shine. Over time, this could lead your hair to be prone to breakage.
More so, silicone can also prevent good ingredients from going through the cuticles, since it works by creating protective layers. Thus, you won’t be able to get the benefits from those nourishing ingredients.
The silicones in Herstyler hair serum are non-water-soluble, meaning they won’t get rid of water only. You’ll need a clarifying shampoo to help remove the residue of these silicones for a few sessions.
Aloe Vera
Extracted from the aloe plant soothes, aloe vera is a hero ingredient for people with dry hair and scalp.

Aloe vera is very beneficial in terms of hydration as it can lock in moisture and attract moisture from the environment. It also has been shown to help calm itchy and inflamed scalp caused by dandruff, which is great for people with Seborrheic dermatitis.
Vitamin E (as Tocopheryl Acetate)
Loaded with antioxidants, vitamin E is vital to protect your hair from free radicals and sun damage.

It has the ability to create protective barriers on your hair and revive shine. Eventually, this leads to reduced breakage, preserves moisture, and protects hair from damage. Vitamin E is also essential to support your scalp health and provide a strong environment for hair to grow.
Argan Oil
Many people refer to it as “liquid gold” since this oil has been shown to provide abundant benefits for hair and skin.

Argan oil is full of fatty acids which are beneficial to maintain your hair moisture. More so, this oil adds a protective barrier to your hair to prevent breakage during heat styling and reduce damage due to coloring.
After discussing the benefits of each ingredient, let’s find out where you can get the serum.
