Hair

As compared to traditional agriculture, hydroponic farming uses less space and less water, plus it requires no soil. It still does require a growth medium, though – and scientists have recently created a better such medium, derived from human hair.

A huge new study looking at the symptoms of long COVID in non-hospitalized patients has identified a diverse set of symptoms, including reduced libido and hair loss, and suggested reclassifying the condition into three distinct groups.

Researchers at UC Riverside have identified a single protein that seems to control when hair follicles die. Armed with this new information, it might eventually be possible to reverse the process and stimulate hair regrowth.

Scientists probing the intricate machinery behind hair growth have uncovered a previously unknown role for a signaling molecule, whose messages were found to be critical to new growth and could be leveraged to address hair loss in humans.

The FDA has followed highly promising results from trials demonstrating the hair regrowth potential of a common arthritis drug with a landmark approval, giving baricitinib the green light as a treatment for severe alopecia areata.

In pursuit of a treatment for alopecia areata, an autoimmune disorder that causes hair loss, scientists have found new success by repurposing a common arthritis drug which proved effective in around a third of subjects.

A new player has entered the hair loss scene promising a new form of treatment that takes a more efficient approach to regenerating lost follicles, by skipping a common step in the production of induced hair stem cells.

A new study has uncovered a previously unknown mechanism whereby stem cells can lose their adhesiveness and become dislodged from hair follicles in aging mice, leading to hair loss. They've also identified genes that could be key to reversing the process.

Scientists in China are throwing a new potential hair loss treatment into the mix that uses a dissolvable microneedle patch to stimulate hair growth, with the technology proving high effective in mouse models of hereditary pattern baldness.

A new study has produced first-of-a-kind scientific evidence of the connection between stress and graying hair, identifying proteins that seem to drive this process while also demonstrating how it might even be reversed.

Harvard scientists have published a paper detailing how stress hormones suppress the regenerative capabilities of hair follicles, adding to our knowledge around hair loss and raising new possibilities around how it might be tackled.

Researchers studying hair loss Japan have shed yet more light on the topic, discovering a new mechanism by which dividing cells can drive hair follicles to exhaustion, subduing their regenerative abilities as we age.
