Glossary Seasonal Changes

variations in environmental conditions due to Earth's orbit

Seasonal changes refer to the variations in environmental conditions that occur as the Earth orbits around the Sun, leading to different seasons such as winter, spring, summer, and autumn. These changes can affect various biological processes, including hair growth cycles, where some individuals may experience increased hair shedding in the fall and spring due to shifts in daylight and temperature.

community Prolactin the Cause of Hair Loss? ABS-201 the Cure?

29 upvotes 2 months ago

Prolactin may contribute to hair loss, but targeting its receptor won't cure androgenetic alopecia. ABS-201 could be a useful alternative or adjuvant therapy, similar to JAK inhibitors, but not more effective than HMI-115.
