TLDR

  • Human hair, primarily keratin, offers protection, sensory input, and reflects overall health, according to specialists.
  • Hair follicles host a microbiome that aids in protection and can influence hair growth and color.
  • Hair serves as a biological record, with a centimeter reflecting about a month of information about substance use, toxin exposure, or stress levels.

In Uruguay, El País delves into the fascinating science behind human hair, moving beyond its aesthetic appeal to explore its crucial biological functions. The article highlights how our hair acts as a protective layer, a sensory organ, and even a health indicator, drawing insights from cellular biologists and dermatologists.

una persona posee alrededor de 100.000 folículos pilosos en el cuero cabelludo, cada uno capaz de producir cabello y pigmento mediante un proceso comparable a una “impresora 3D”.

— Maksim PlikusExplaining the biological process of hair production.

We learn that the scalp's 100,000 hair follicles are intricate biological printers, producing hair and pigment. More than just strands, they harbor a complex microbiome—a community of bacteria, viruses, and fungi that shields us from infections and influences hair characteristics. This microbial ecosystem is vital for our well-being, a fact often overlooked in everyday life.

— Ralf PausDescribing the function of the hair follicle microbiome.

The article emphasizes the hair follicle's role as a sophisticated sensory network, connected to the brain's emotional centers. This explains why we get goosebumps and why hair removal can be painful. It transforms our hair from a simple covering into a biological sensor, alerting us to the slightest touch or air movement, much like our eyelashes.

Furthermore, the piece reveals hair's function in skin healing, with stem cells from follicles migrating to repair wounds. It also touches upon the hair's internal clock regulating growth cycles and its potential as a biological logbook, capable of revealing past exposures to toxins or stress. This deep dive into the science of hair underscores its multifaceted importance, offering a perspective that values biological function as much as appearance.

este ritmo está sincronizado con el ciclo circadiano, lo que influye en la velocidad de crecimiento capilar a lo largo del día.
