New Hair Loss Drug Approved: Restores 80% of Hair Loss In Some Alopecia Patients   Science Alert - June 28, 2023

Severe hair loss from the autoimmune condition, alopecia areata, could be reversible in some patients if they take a daily oral drug for several months.




Studies uncover new approaches to combat hair loss in men and women   Medical Express - June 25, 2019
Two recent studies highlight novel ways to combat pattern hair loss in men and women using small molecules such as JAK inhibitors that reawaken dormant hair follicles, as well as stem cell therapies aimed at growing new follicles.




Drug reverses one baldness type; is male pattern next?   CNN - October 19, 2016
In his mid 40s, Mike Thomas went bald. Not a "little bald spot in the back" kind of bald or "receding hairline" kind of bald, but almost totally and completely bald. He was diagnosed with alopecia areata, an autoimmune disease, and he was devastated. He looked, by his own description, like a "freak," with his eyebrows and eyelashes completely gone. He could feel it when people looked at him. Some of them quietly asked whether he had cancer.




First gray hair gene found, plucked out of research   CNN - March 1, 2016
Just like those first silvery strands that stubbornly start cropping up in an otherwise pleasantly pigmented head of hair, the genes responsible for gray hair have been evading science's grasp. Brunettes, redheads, towheads -- they all have snippets in the DNA they can thank, or curse. But for those robbed of their hair color, the genetic suspect was at large. Now researchers may have tracked down the first gene linked to gray hair, a search involving the hair types and genomes of more than 6,000 people living in five Latin American countries. They looked in these populations because they represent a good mix of backgrounds: Europeans and their sometimes fair or curly hair, Native Americans and African-Americans and their characteristic dark and straight or kinky hair.




Can Hair Act as a Sixth Sense, Protecting us from Danger?   Ancient Origins - December 28, 2015
Humans have ever styled their hair in a multitude of creative and symbolic ways, and the various cuts, colors and presentations reflected across the ages are nearly unlimited. But does hair serve us in more ways than providing simple warmth and good looks? There are some who believe that hair is directly associated with sensory power and it serves as an extension of our nervous system.




Are Tweezers the Key to Treating Baldness?   Epoch Times - April 10, 2015
Researchers have demonstrated that by plucking 200 hairs in a specific pattern and density, they can induce up to 1,200 replacement hairs to grow in a mouse. The team showed that this regenerative process relies on the principle of 'quorum sensing,' which defines how a system responds to stimuli that affect some, but not all members. In this case, quorum sensing underlies how the hair follicle system responds to the plucking of some, but not all hairs. Through molecular analyses, the team showed that these plucked follicles signal distress by releasing inflammatory proteins, which recruit immune cells to rush to the site of the injury.




Drug Could Regrow Hair in Some with Hair Loss   Live Science - August 17, 2014
Most hair-loss drugs currently available may stop hair loss, but don't cause hair to regrow. Now, new research suggests that a drug already used to treat people with other conditions could restore hair growth in patients with one disease that can cause hair loss. In a small new study, three people who took a drug called ruxolitinib daily for four to five months saw a complete regrowth of their hair. The patients had a condition called "alopecia areata", which is an autoimmune disease that causes the loss of hair from the scalp or other areas of the body. The drug used in the study is already approved by the Food and Drug Administration to treat people with myelofibrosis, a serious bone marrow disorder.




Wavy vs. Straight: Physics of Curly Hair Teased Out   Live Science - March 3, 2014
The first detailed model of a 3D strand of curly hair has been created, a development that could be a boon for the film and computer animation industries, researchers say. Previously, scientists had no simple mathematical way to describe the motion of curly hair, including the way curls bounce as they move around. As such, many animated characters had hair that was either rigidly straight or only swung from side to side. Now, researchers at MIT, in Cambridge, Mass., and the UniversitŽ Pierre-et-Marie-Curie (UPMC), in Paris, are teasing out the physics of curly hair. To build their model, the scientists used flexible rods to examine varying degrees of curliness.




The physics of curly hair: Researchers develop first detailed model for a 3-D strand of curly hair   Science Daily - February 13, 2014
The heroes and villains in animated films tend to be on opposite ends of the moral spectrum. But they're often similar in their hair, which is usually extremely rigid or -- if it moves at all -- is straight and swings to and fro. It's rare to see an animated character with bouncy, curly hair, since computer animators don't have a simple mathematical means for describing it. But now, researchers have developed the first detailed model for a 3-D strand of curly hair.
