Common Myths About Beard Growth

There’s a lot of misinformation out there when it comes to growing a beard. Let’s clear up some of the biggest myths:

  • Myth: Shaving makes your beard grow back thicker.

    • Fact: Shaving only cuts hair at the surface—it doesn’t affect the root or speed up growth.
  • Myth: All men can grow thick beards.

    • Fact: Genetics play a major role. Some men naturally have denser facial hair than others.
  • Myth: Beard oils and balms make hair grow faster.

    • Fact: While they keep your beard healthy, they don’t directly increase growth speed.
  • Myth: A patchy beard means you’ll never grow a full one.

    • Fact: Many beards start patchy—growth often fills in over time with proper care.

The Science Behind Facial Hair Growth

Beard growth is influenced by several biological factors:

  • Genetics – Your DNA determines how thick and full your beard will be.
  • Testosterone & DHT – Higher levels of these hormones promote beard growth.
  • Age – Facial hair tends to develop more fully in your mid-20s to 30s.
  • Health & Nutrition – A balanced diet, exercise, and sleep all support healthy hair growth.

While you can’t change genetics, you can optimise your lifestyle to encourage better beard growth.

Proven Ways to Support Healthy Beard Growth

If you want to maximise your beard’s potential, follow these science-backed strategies:

  • Eat a Nutrient-Rich Diet – Protein, biotin, and vitamins like B12 and D support hair growth.
  • Stay Active – Exercise boosts testosterone, which can help with beard thickness.
  • Get Enough Sleep – Rest is crucial for cell regeneration and hair growth.
  • Reduce Stress – High stress levels can slow down hair growth and cause shedding.
  • Maintain a Beard Care Routine – Keeping your beard clean and moisturised helps prevent breakage and patchiness.
