How Do Eyebrow Serums Work?

How Do Eyebrow Serums Work

The best brow growth serums contain minerals and vitamins such as biotin, peptides, panthenol, and oils that help moisturize and strengthen eyebrow hairs. These eyebrow growth oils include castor oil, jojoba oil, and argan oil, and they help strengthen hair follicles, hydrate the scalp, prevent breakage, and enhance the growth of thicker eyebrows. While some of these ingredients may not promote the growth of new hairs, they help strengthen existing hairs and prevent breakage. By doing so, the eyebrows appear thicker and fuller once you use these eyebrow growth products.

Do Serums Really Help Eyebrows Grow?

According to Holmes a skin expert, brow serums do work for some individuals. The skin expert says she recommends these brow growth serums to her clients for their daily brow regime. “I suggest starting with a stronger hormone-included eyebrow thickening serum if the client is a good candidate or trying a more nutrient-based and natural serum if the client cannot tolerate certain ingredients,” she explains.

Common Ingredients in the Best Eyebrow Growing Serum


  • Biotin :

    Biotin is a water-soluble vitamin and a form of vitamin B. according to skin expert Imashi Fernando, MD, biotin is a common ingredient in hair growth supplements as it helps promote thicker and fuller hair. Biotin can also be taken orally as a supplement to promote healthy hair and nails, explains the expert.

    According to a review in the Skin Appendage Disorders Journal, biotin is an ingredient that has gained popularity in hair products because of its effectiveness in promoting healthy hair and nail growth, while preventing hair loss.

  • Peptides :

    Peptides are available as dietary supplements and may also be used in skin and hair products. Experts support that peptides in hair products may help improve hair follicle size. As the size of the follicles increases, the hair appears to be thicker and fuller. Most eyebrow growth serums include this powerful ingredient.

    According to the International Journal of Molecular Sciences, fish collagen peptides have bioactive properties, including enhancing the growth of hair and preventing hair loss.

Choice Ingredients for Follicle Conditioning

  • Castor oil :

    Rachel Nazarian, MD, a board-certified dermatologist says that castor oil is nutrient dense and it has many benefits for the hair. This includes promoting hair growth, strengthening hair strands, nourishing dry scalp, and protecting hair breakage. While the hair is nourishing, according to King there is no solid evidence to support that castor oil promotes hair growth.

    A publication in the National Library of Medicine reveals that treating hair with over-the-counter oils like castor oil may help increase hair luster, treat scalp and hair conditions, improve hair quality, and promotes hair growth.

  • Hyaluronic acid :

    Ginger King a cosmetic chemist says, “Hyaluronic acid comes in different forms, and the least expensive version is Sodium hyaluronate, commonly used in hair care products.” According to Bridgette Hill, a certified trichologist and scalp therapist, hyaluronic acid in brow growth serum helps hydrate the scalp, plump the hair, reduce fizziness, restore hair porosity, and hydrate the scalp.

    According to BioMed Research International, hyaluronic acid promotes the growth of new hair follicles, restores cell viability, and improves hair hydration.

  • Vitamin E, D, Jojoba oil Argan oil :

    According to skin and hair experts, eyelash and eyebrow growth serum may include vitamins E, and D, Jojoba oil, and argan oils. These oils are safe and effective in promoting hair growth and enhancing eyebrow thickness. Argan oil and jojoba oil help moisturize and strengthen the scalp and repair split ends.

    According to research done by Autumn Roberts and published in the Polymers Journal, argan oil, and jojoba oil may help treat scalp disorders and protects the hair against oxidative damage.

Ingredient to Avoid :

Hair and skin experts recommend that you research the ingredients in the eyebrow serum to ensure you know what you are putting on your skin. Some ingredients may irritate the sensitive skin around your eyes. Jamilan, a skin expert, warns people against using eyebrow enhancement serums that have synthetic prostaglandins as they may irritate the skin. Avoid eyebrow growth products that have Trifluoromethyl Dechloro Ethylprostenolamide, Isopropanol Phenyl-hydroxyl-pentene Dihydroxy-cyclopentyl-heptanoate, Isopropyl cloprostenol, and Dechloro Dihydroxy Difluoro Ethylcloprostenolamide. Ensure you select a safe product made in TGA-approved labs and FDA-certified facilities since they will be free of any irritant chemicals.

How to Choose the Best Eyebrow Enhancers Serums?

Before buying eyebrow enhancement serums, there are some factors such as application method, formula type, ingredients, and other personal factors that you need to put into consideration. Here are some of the factors:

1. Ingredients :

Before buying a brow serum, check on its active ingredients. Active lipid compounds such as prostaglandins are common in eyebrow and eyelash growth serums as they help prolong the active phase of hair growth. However, they may cause hyperpigmentation, skin irritation, swelling, burning, and redness. Pregnant and nursing women should not use products with these ingredients. Natural eyebrow serums are gentler as they contain ingredients that do not have any side effects.

2. Formula :

As with skincare serums, the best brow serums should be lightweight in consistency to allow easy absorption into the skin. A brow serum that is too thick will not deeply penetrate into the skin layer and may not reach the hair follicles. The right consistency of a brow serum helps stimulate hair growth and support thicker brows.

3. Application :

Application is important when it comes to makeup, skincare, as well as brow serums. Skin experts recommend that before you apply your eyebrow serum; ensure you clean your face thoroughly to remove any makeup. Wait for the face to dry completely as water may dilute the serum and interfere with efficiency. Apply the serum on the eyebrows. Give it three to five minutes to dry and then you can apply other skincare products.
