Hair Follicles: Scars' Unexpected Healers
January 2023
Imperial College London

Introduction
Imagine turning scars into almost brand-new skin with just a few hair follicles! Researchers at Imperial College London have cracked a code in scar treatment that sounds like something out of a sci-fi novel. By transplanting hair follicles into scarred skin, they've seen scars begin to act like their unscarred counterparts—regaining cells, blood vessels, and even changing their genetic tunes. This groundbreaking study not only promises a new dawn for those with visible scars but also hints at future treatments for internal scarring. Dive into this fascinating research and see how a bit of hair can make a big difference!

Healing Beyond the Surface
Imagine having a scar that doesn't just fade away but transforms back into skin so healthy, it's like the injury never happened. That's not a snippet from a sci-fi novel but a real possibility, thanks to groundbreaking research from Imperial College London. By transplanting hair follicles into scars, scientists have started turning scarred, lifeless skin into vibrant, functional tissue again. This isn't just about looking good; it's about feeling good, inside and out. Scars can affect how our organs work, how we move, and how we perceive ourselves. So, understanding and potentially reversing scarring can change lives globally, from improving organ function to boosting confidence. For you, this could mean a future where the marks of past injuries don't dictate your skin's story.

Collagen remodeling
The process by which the structure of collagen, a key protein in connective tissue, is altered, affecting tissue stiffness and function.

Gene expression
How information from a gene is used in the synthesis of a functional gene product, like proteins, that determine cellular structure and control cell function.

Normotrophic scars
A type of scar that forms level with the skin, typically after surgery, which doesn't cause a significant change in tissue elevation.

Biopsy
A medical test involving the extraction of sample cells or tissues for examination to understand disease presence or the condition of tissues.

Dermis
The thick layer of living tissue below the epidermis that forms the true skin, containing blood capillaries, nerve endings, sweat glands, hair follicles, and other structures.
