Did you mean Stress Response?

GlossaryStress Response

body's reaction to perceived threats, involving hormone release

The stress response is the body's way of reacting to perceived threats or challenges, often referred to as the "fight-or-flight" response. It involves the release of hormones like adrenaline and cortisol, which prepare the body to either confront or flee from the stressor. This response can affect various bodily functions, including heart rate, digestion, and even hair growth, potentially leading to conditions like stress-induced alopecia.

research Skin Gamma Delta T Cell Gene Expression Highlights Stress Response in Alopecia Areata 2258104

July 2026 in “The Journal of Immunology”

This study investigates the role of γδ T cells in alopecia areata, an autoimmune disease causing patchy hair loss. By analyzing single-cell RNA sequencing data from both mouse and human skin, researchers identified that γδ T cells upregulate stress response genes, such as HSP70, HSP90AA1, and others, during alopecia areata. In mice, these cells also increase expression of chaperones like CD74 and receptors like Ly6A/E, particularly around hair follicles and skin layers. The study highlights that T cells undergo significant stress responses, suggesting they could be potential targets for therapeutic interventions in alopecia areata.

community Intermittent fasting reduces hair growth?!? :(

in Research/Science 38 upvotes 1 year ago

Intermittent fasting may inhibit hair growth by triggering a stress response that affects hair-follicle stem cells. Some users believe genetics and DHT play a larger role in hair loss, and treatments like Minoxidil and Finasteride are mentioned as ineffective for some.

community What are all of the lifestyle factors that can speed up MPB?

in Chat 39 upvotes 2 years ago

Genetics mainly cause hair loss, but diet, stress, smoking, and alcohol can worsen it. Treatments include finasteride, minoxidil, and lifestyle changes like a healthy diet and avoiding caffeine.

community It's not fair I'm the one who's supposed to have the most hair.

in Satire 78 upvotes 11 months ago

People discussed hair loss treatments, including finasteride, minoxidil, and microneedling, with varying results and concerns about genetics and hormone levels. Some users shared personal experiences with medication dosages and side effects, while others mentioned the impact of stress on hair loss.

community Going to try and reverse MPB naturally.

in Treatment 55 upvotes 4 years ago

A user is trying to reverse male pattern baldness (MPB) naturally by taking high doses of Vitamin D, improving diet, exercising, reducing stress, and other lifestyle changes, but plans to use finasteride if no results are seen in 60 days. Other users are skeptical, advising medical treatments like finasteride and warning against potential vitamin D overdose and the ineffectiveness of natural remedies for genetic hair loss.
