Best Eyebrow Growth Serum for Bolder Brows

Best Eyebrow Growth Serum

Gone are the days where we'd over-pluck our poor eyebrows to a mere pencil-thin line, now the new #browgoals are thicker, fuller, and borderline-bushy brows that you'll often see on supermodels and celebrities all through Instagram feeds. With this comes the desire for everyone to spruce up their brow game into a full, bold arch, which is where the best eyebrow growth serum comes into the picture.

There's a whole line of the latest non-prescription brow serums that are designed to strengthen and enhance the thickness of your brow hairs. So now you can have some little help in nudging things in the right direction, stimulate new hair growth in the relatively sparse areas.

With all these new and improved non-prescription brow growth serums, you no longer need first to see a doctor for a prescription as you'd do with the Lash and brow enhancer, Latisse. Instead, consistently follow their directions for application, and some could show results as early as 2 weeks in.

Do Eyebrow Serums Actually Work?

Rationally, yes and no. The efficiency of the best eyebrow growth serums will totally depend on your goal and idea of ' it works. Your random high school friend might swear by some brow serum that's going to 'transform' your skimpy arches into full Zendaya-level brows? Nope, nada! But will they enhance your existing brow hairs, making them look fuller, thicker, and much healthier? Definite yes.

The best eyebrow growth serums are formulated using great ingredients such as hyaluronic acid, vitamins, and proteins that condition existing brow hairs. Creating this happier place makes brows healthy and, in turn, creates the ideal environment that stimulates new growth. Just like hair on your head, brow hairs will need to be nurtured to stimulate growth and thrive, and the best brow growth serums can help with that.

The only brow serum that's FDA-approved growth is Latisse, an eyelash growth serum that's only available by prescription. Among other effective ingredients, Latisse contains Bimatoprost, which is known to help grow lash and brow hairs. But, it also comes with potential side effects, which include irritation and rashes, so you'll need to see a doctor first before using it.

Even though the best eyebrow growth serums are formulated to improve the thickness of each brow hair follicle, and in the long run, stimulate improved growth, don't expect the results overnight. Most cosmetic and clinical research suggests that best results could take anywhere between 3-6 months before you notice any visible changes.

Experts suggest looking for non-prescription brow serums with formulas that contain biotin and panthenol, amino acids, keratin, antioxidants, hyaluronic acid, and peptides. And because we know you don't have the time or energy to ravage through millions of product labels for the best on this list, we went ahead and did it for you.

What Factors to Consider for The Best Eyebrow Growth Serum?

A) Does it Contain Peptides?

Peptides are amino acids in the form of synthetic strings that penetrate deep into your hair and skin to boost and promote hair growth by producing proteins such as keratin and collagen. For example, many eyebrow growth serums use a peptide complex that uniquely blends different peptides that work together to get the brow job done.

B) Does it Contain Hydrators?

Hydrators such as Hyaluronic acid, panthenol, glycerin, and vitamin B5 are great ingredients to look out for in your brow enhancing serum, especially if you have fragile hairs that are in dire need of hydration.

C) Does it Contain A Conditioner?

Seed and fruit oils such as castor, hemp, or rosemary help soften brow hairs and contain essential omega fatty acids to help promote strength and shine.

  •  Castor oil is probably the most common yet effective way to grow eyebrows and hair in general naturally. Organic castor oil contains roughly 90% ricinoleic acid that helps promote hair growth. But some may be allergic to it, so it would be wiser to do a patch test first before applying it to your eyebrows
  • Coconut is another example brimming with the essential nutrients, vitamins, and fatty acids, that stimulate dormant hairs and promote faster brow growth. Regularly massage it around your eyebrows to moisturize and hydrate the area and also prevent further damage to your delicate brow hair

D) Any Vitamins?

Vitamins such as Vitamin E acts as an antioxidant that helps soften and protect hair, while biotin (Vitamin B) helps strengthens it.

  • Olive oil - It moisturizes and nourishes the brows and helps keep the hair from falling. Olive oil helps prevents unnecessary breakage of hair, ensuring that your eyebrows have a thicker, bolder, and stunning look. Additionally, large quantities of Vitamin E also help in giving the eyebrow hair a darker loo, making your eyebrows appear thicker than they actually are
  • Onion juice is also another rich source of sulfur, Vitamins (B and C), Selenium, and minerals, all of which work so well to enhance brow growth. Low levels of collagen cause eyebrow hair to fall out, but the sulfur helps rebuild collagen back and strengthen the follicles that, in turn, help eyebrows grow much thicker and darker

E) Any Proteins?

The best eyebrow growth serums often contain wheat protein, among other strengthening proteins that have been found to effectively help repair the damaged hair bonds of existing hairs and improve their elasticity. So if you struggle with eyebrow hairs that keep falling out, this is definitely worth looking at.

Frequently Asked Questions on the Best Eyebrow Growth Serum

1. How to stimulate healthy eyebrow growth?

  • Eating a healthy balanced diet may help promote optimal growth
  • Eating foods high in iron since iron deficiency causes anemia which is a common cause of thinning hair follicles and hair loss that also affects eyebrows
  • Avoid waxing, plucking, or threading eyebrows
  • Use of products that contain a good amount of ingredients like Castor oil or Biotin
  • Use an eyebrow enhancing serum
  • Check with your doctor for Bimatoprost (Latisse) prescription

2. Does Vaseline help encourage the growth of fuller brows?

Vaseline can help protect and moisturize eyebrows, but Vaseline jelly doesn't contain any ingredients that could help in eyebrow growth or encourage hair growth in general. So no evidence shows that Vaseline can promote hair health or grow eyebrows.

3. Can you regrow your eyebrows?

Naturally, eyebrows will grow back, but your overall health and ag will depend on how fast they regrow. You'll need to be a little patient, avoid waxing or plucking them out, and include items in your diet that help promote regrowth. You should consult a doctor if your eyebrows start to fall out or stop growing for no apparent reason.

4. Why are eyebrows so sparse?

Sparse brows or thinning of hair can either occur on one or both eyebrows. Other than overplucking, other common causes include an infection, hormonal imbalances, dermatological conditions, an overactive immune system, or immune system dysfunction. Frail hairs could also be caused by chronic emotional stress, nutritional deficiency, or physical trauma on your brow area.

5. How to permanently fix thin eyebrows?

  • Stop tweezing - eyebrows may grow a little wild on random spots and seem unkempt, but by not plucking or waxing them out, you'll have a better chance of growing bolder brows
  • If you need to tweeze them, do it in a row method
  • Exfoliate for healthy brows
  • Use eyebrow serum
  • You can also fill them in
