Hair

Unlike normal skin, scar tissue doesn't contain any hair follicles. New research now indicates that when such follicles are transplanted into scar tissue, that tissue changes to become much more like uninjured skin.

Scientists in China researching advanced treatments for a common form of hair loss have found success through a novel microneedle patch, which was used to tackle oxidative stress and regenerate hair in bald mice.

Scientists studying the way hair follicles take shape in the human body have found new success in the lab, demonstrating a way of growing fully matured forms of them in culture with hopes of pioneering advanced treatments for hair loss disorders.

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.
