Hair loss can signal serious health issues, not just cosmetic concerns.

Lipocalin-Type Prostaglandin D2 Synthase (L-PGDS) is a protein that plays many roles in the body, including sleep regulation, pain management, food intake, and protection against harmful substances. It also affects fat metabolism, glucose intolerance, cell maturation, and is involved in various diseases like diabetes, cancer, and arthritis. It can influence sex organ development and embryonic cell differentiation, and its levels can be used as a diagnostic marker for certain conditions.

Eating too much or too little vitamin A can cause hair loss.

CO2 laser treatment for aging skin significantly changes immune system-related genes.

Researchers found genes linked to feather growth speed in Shouguang chickens, highlighting two genes that might explain differences in feathering.

Increased FGFR2b signaling, influenced by androgens, plays a role in causing acne.

A protein called IL-36γ causes skin side effects from certain cancer treatments when combined with a common skin bacteria.

Scientists made structures that look like human hair follicles using stem cells, which could help grow hair without using actual human tissue.

B2m-free HLA variants may be a new class of HLA important in immune responses and diseases.

Nanotechnology could improve hair regrowth but faces challenges like complexity and safety concerns.
