Are you missing those bushy, well-shaped eyebrows due to excessive plucking, years of shaving, or other reasons? We’ve all been there at some point. Eyebrows are an important feature that frames your face, and the struggle is real when they’re absent or sparse. Well, the good news is, that eyebrows generally take around four months to grow back. Let’s delve into why that is and how you can optimize your brow-regrowth journey.

Why Do Eyebrows Fall Out in the First Place?

Loss of eyebrow hair can happen for various reasons. Some of the most common culprits include:

  • Excessive Plucking or Shaving: Years of shaping your brows can thin them out.
  • Hormonal Imbalance: Conditions like hypothyroidism can also lead to brow loss.
  • Nutritional Deficiency: Poor diet can significantly contribute to sparse eyebrows.
  • Medical Treatments: Chemotherapy is often linked to hair loss, including that of the eyebrows.

Your age, the specific reason behind the loss, and other variables can affect how long it will take for your brows to grow back.

Do Eyebrows Really Regrow?

Contrary to the popular myth that once you lose your eyebrow hair, it’s gone forever, research confirms that they generally do grow back. A study from 1999 showed that shaved eyebrows regrow naturally over time. In this study, photographs were taken at intervals to track regrowth over six months. Except for one participant with light-colored, sparse brows, all subjects’ eyebrows had returned to normal after about four months.

Understand the Growth Cycle of Brow Hair

Eyebrow hair growth follows three phases:

  • Anagen: This is the active growth stage that lasts 30 to 45 days. During this phase, your eyebrows grow at a rate of about 0.14mm to 0.16mm per day.
  • Catagen: Lasting 2 to 3 weeks, this transitional phase sees the hair follicles shrink.
  • Telogen: This resting phase lasts between 4 and 8 weeks and ends when the old hairs fall out, and new hairs begin to grow, thus restarting the cycle.

Methods and Their Regrowth Time


If you’ve shaved your eyebrows, you’re in luck; because shaving only removes hair above the skin’s surface, you’ll likely see regrowth within a week or two.


If you’ve plucked your brows, new hair will regrow, but it could take anywhere from four to six weeks due to the hair being removed from the root.

Waxing and Threading

Both these methods remove hair from the root, and regrowth can take several weeks.


This technique doesn’t inhibit the growth of natural hair; rather, it creates the appearance of additional hairs.

Factors Affecting Brow Regrowth

Several elements can affect the speed at which your brows grow back:

  • Skin conditions like eczema or psoriasis
  • Stress and anxiety
  • Hormonal changes like pregnancy
  • Aging and related thyroid conditions
  • Chemotherapy treatments

Strategies for Speeding Up Eyebrow Growth

  • Avoid the Magnifying Mirror: Allow your brows to recover by not obsessing over every tiny hair.
  • Castor Oil: While not scientifically proven, many people swear by its ability to stimulate hair growth.
  • Pluck Post-Shower: Skin is softer and follicles are more easily released.
  • Focus on Nutrition: Consider supplements like iron and biotin after consulting with your healthcare provider.
  • Natural Oils: Vitamin E, olive oil, and coconut oil are good natural options for promoting eyebrow health.
  • Topical Treatments: Products like Latisse and over-the-counter Rogaine could be effective, but consult a healthcare provider before use.


There’s no magic bullet for instant eyebrow regrowth; it’s a slow and steady process influenced by age, genetics, and overall health. A balanced diet rich in essential nutrients can certainly help, as can certain topical treatments. If you’re concerned about abnormal eyebrow loss, it might be worth a visit to your healthcare provider to rule out any underlying issues. After all, eyebrows don’t just grow overnight—but with some patience and care, you’ll be back to your best brow game before you know it.
