Did you mean Stress Response?

Glossary Stress 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 observed that in both mouse and human models of alopecia areata, T cells exhibit a stress response involving heat shock proteins and other regulatory markers, suggesting their potential as targets for therapeutic intervention in this autoimmune skin disease.

research Evaluation of Personalized Skincare Through in-silico Gene Interactive Networks and Cellular Responses to UVR and Oxidative Stress

11 citations , October 2022 in “Clinical Cosmetic and Investigational Dermatology”

In this study, SNPs in genes affecting skin pigmentation were linked to each skin type's unique response to environmental stress, suggesting potential for personalized skin care products.

research Genome-wide p63-Target Gene Analyses Reveal TAp63/NRF2-Dependent Oxidative Stress Responses

7 citations , January 2024 in “Cancer Research Communications”

This study found that TAp63 and ΔNp63 isoforms in the p63 family interact with different transcription factors to regulate distinct transcriptional programs, affecting various biological functions like metabolic pathways, oxidative stress response, and epithelial morphogenesis in mouse epidermal cells.

research Increased expression of the gene for the Y₁ receptor of neuropeptide Y in the amygdala and paraventricular nucleus of Y₁R/LacZ transgenic mice in response to restraint stress

22 citations , April 2004 in “Journal of Neurochemistry”

In this study, acute restraint stress increased Y1 receptor gene expression in the amygdala and PVN of transgenic mice, but this effect was not due to elevated neuroactive steroid concentrations, indicating a potential ligand-induced mechanism.

research Deletion of vitamin D receptor with calcium sensing receptor in keratinocytes promotes epidermal tumorigenesis by limiting dna repair and oxidative stress response genes

March 2026 in “The Journal of Steroid Biochemistry and Molecular Biology”

This study found that mice lacking both vitamin D and calcium-sensing receptors in epidermal keratinocytes are predisposed to developing squamous cell carcinoma as they age, due to impaired oxidative stress response and reduced DNA repair capabilities.

community Intermittent fasting reduces hair growth?!? :(

35 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?

34 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 1 year 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 A stress hormone has been found to signal through skin cells to repress the activation of hair-follicle stem cells in mice

30 upvotes 5 years ago

Stress can lead to hair loss by affecting hair-follicle stem cells, and this loss is harder to recover from if one has male pattern baldness (MPB). Treatments like finasteride and minoxidil are used to address hair loss, but stress-related hair loss differs from androgenic alopecia.

community I am about to cry, umI hate my gens

in Chat 58 upvotes 1 year ago

Hair loss affects confidence, with discussions on treatments like finasteride, minoxidil, and RU58841. Emphasis is placed on self-acceptance and building confidence beyond appearance.
