Scientific research on natural beard growth oils

💬 Introduction

You've probably heard the claims: "This oil will grow your beard fast." But what's real, and what's hype? The beard care industry is booming, but few people understand the science behind natural beard growth oils — the ingredients that actually nourish hair follicles and encourage thickness.

In this post, we'll break down research-backed components found in high-performing beard oils, explain how they affect your hair growth cycle, and why oils like those in GrindNShine work better than synthetic knockoffs.

🧬 How Beard Growth Works (in 30 Seconds)

Your beard grows in cycles:

  1. Anagen – Active growth phase (can last years)
  2. Catagen – Transition phase (growth slows)
  3. Telogen – Resting/shedding phase

Natural oils work by nourishing the skin and follicles during the anagen phase and helping new hairs stay strong through the cycle.

🌿 Top Natural Ingredients Backed by Science

Here's what the studies and science say about key natural oils and actives:

Biotin (Vitamin B7)

What it does: Supports keratin production and follicle health.

Research: A 2012 study showed improved hair thickness and shine in biotin-deficient individuals after supplementation.

In Beard Oil? Not directly — but pairing beard oil with a biotin-rich diet or supplement boosts overall growth results.

Castor Oil (Ricinoleic Acid)

What it does: Enhances blood circulation to follicles; may reduce inflammation.

Research: Shown to increase prostaglandin E2 levels, which stimulate hair follicles.

In GrindNShine: Present in Level 3 Thickening Oil for maximum follicle activation.

Jojoba Oil

What it does: Closely mimics sebum (skin oil); hydrates follicles and reduces breakage.

Research: Proven to reduce transepidermal water loss and support skin barrier function.

Bonus: Non-comedogenic — won't clog pores under your beard.

Peppermint Oil (Menthol)

What it does: Increases circulation and follicle depth.

Research: A 2014 Korean study found peppermint oil outperformed minoxidil (Rogaine) in hair growth rate and thickness in mice.

In Beard Oil? Yes — a popular essential oil used in growth-focused blends.

Argan Oil

What it does: Rich in Vitamin E and fatty acids for shine and nourishment.

Research: Helps prevent breakage and supports hair shaft elasticity, allowing hair to grow longer without snapping.

In GrindNShine: Found in multiple blends to reduce coarseness and increase manageability.

Moringa Oil

What it does: Antioxidant-rich and anti-inflammatory; protects follicles from oxidative stress.

Research: A 2019 dermatology review highlighted moringa's ability to fight free radicals that damage hair-producing cells.

Exclusive Use: GrindNShine's Level 4 Premium Infused Oil includes moringa as a performance-enhancing ingredient.

🔬 What About Synthetic Growth Oils?

Many products on the market contain:

  • Silicones (only coat hair, don't nourish)
  • Alcohols (dry out skin and cause flaking)
  • Minoxidil (works but with side effects like shedding and irritation)

Unlike natural oils, synthetics often treat symptoms, not causes — and they can disrupt skin health and beard pH levels over time.

🧠 Bottom Line: Nature + Science = Results

Natural beard growth oils are more than grooming trends — they're backed by real research and years of traditional use. When combined in the right formula (like GrindNShine's Level System), they:

  • Encourage blood flow to hair follicles
  • Reduce beard itch and dryness
  • Support thickness and retention
