Alopecia areata, which causes patchy hair loss, is often preceded by stress. Scientists are starting to figure out why through animal studies. When you purchase through links on our site, we may earn ...

Rockefeller scientists uncovered how hair follicle stem cells can switch from growing hair to repairing skin when nutrients run low. The key lies in serine, an amino acid that activates a stress ...

The researchers used mouse skin samples to monitor changes to the fat tissue under the skin, as well as to the hair follicles and the cells that help hair grow, after they caused small injuries to ...

A surprising trigger for hair regrowth may lie in the body’s fat cells. Researchers have shown that mild skin irritation can trigger fat cells to go into panic mode, sending signals to dormant ...

Elon Musk, long rumored to have undergone hair restoration, has become an unlikely symbol of visible rejuvenation—a status marker in the longevity economy. People are becoming biologically younger yet ...

Stress can cause hair to turn gray, or to turn gray earlier than it otherwise would have. This is because of the effect that stress has on melanocytes. Melanocytes are cells that produce melanin, a ...

Researchers have developed a new drug that regrows hair by reactivating dormant hair follicle cells. The approach is different than current treatments, which only slow down hair loss. It reactivates ...

When the skin is injured, a stem cell’s survival instincts kick in. New research reveals that a simple amino acid, serine, helps push stem cells to abandon hair growth in favor of wound healing, ...

While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other parts of the body. For example, when the tiny sensory hair cells in our inner ...

Scientists identify specific genes involved in zebrafish sensory hair cell regrowth, providing new insights that could inform future research into hearing loss treatments. While humans can regularly ...

Zebrafish can regenerate sensory hair cells that humans permanently lose, like those in the inner ear linked to hearing and balance. New research reveals two specific genes that control how different ...
