Is Grey Hair Thicker or Thinner? The Truth Behind Hair Texture and Growth

Is Grey Hair Thicker or Thinner? The Truth Behind Hair Texture and Growth

By Manhattan Grey

One of the most common myths about grey hair is that it's inherently thinner or weaker than pigmented hair. However, scientific research tells a more complex story. A 2011 study revealed that white (non-pigmented) hair can actually be thicker and grow faster than its pigmented counterparts. This is due to an upregulation of keratin and keratin-associated protein genes in grey hair follicles, indicating a biologically active growth process at the root level.

Why Grey Hair Feels More Fragile

Despite these findings, many people with grey curls experience their hair as drier, finer, or more prone to breakage. This is typically due to a thinner cuticle—or outer layer—on each strand, which reduces the hair’s natural moisture retention. As the scalp produces less oil with age, grey hair is more exposed to dryness and environmental stress, which can affect texture and manageability.

  • Thinner cuticle = increased dryness
  • Age-related oil reduction = less natural protection
  • Environmental damage = more susceptibility to breakage

Understanding Hair Texture Change with Age

Grey hair often changes in texture as it loses melanin. This transformation can make it feel wiry, coarse, or even limp—differences that are more about surface structure than the actual thickness of the hair shaft. Genetics, scalp health, and everyday care routines all play a role in how this change manifests.

That’s where a high-quality haircare regimen comes in. For those with grey, curly, or mixed-texture hair, products that restore moisture, strengthen strands, and reduce breakage are a game changer. The key lies not in fighting the nature of grey hair, but in nourishing it into its healthiest state.
