research New effects of caffeine on corticotropin‐releasing hormone (CRH)‐induced stress along the intrafollicular classical hypothalamic–pituitary–adrenal (HPA) axis (CRH‐R1/2, IP3‐R, ACTH, MC‐R2) and the neurogenic non‐HPA axis (substance P, p75NTRand TrkA) inex vivohuman male androgenetic scalp hair follicles
Caffeine may help reduce stress-induced hair loss.
research 653 Substance P ameliorates epidermal thickness, basal cell density, and asymmetric stem cell self-renewal in skin with decreased sensory innervation
Substance P helps restore skin thickness and cell renewal when sensory nerves are reduced.
research Tissue and serum levels of substance P in trichodynia of androgenetic alopecia patients
Higher substance P levels may cause discomfort in hair loss patients.

research Antioxidation, Anti-Inflammation, and Regulation of SRD5A Gene Expression of Oryza sativa cv. Bue Bang 3 CMU Husk and Bran Extracts as Androgenetic Alopecia Molecular Treatment Substances
Rice husk and bran extracts from the Bue Bang 3 CMU variety can potentially treat hair loss due to their antioxidant, anti-inflammatory, and anti-androgenic properties.
research Probing the Effects of Stress Mediators on the Human Hair Follicle
Stress-related substance P may lead to hair loss and negatively affect hair growth.
research Neuroimmunology of Stress: Skin Takes Center Stage
Stress can worsen skin and hair conditions by affecting the skin's immune response and hormone levels.
research Heme Oxygenase and the Skin in Health and Disease
HO-1 helps skin health and healing but can worsen melanoma; it's a potential treatment target for skin diseases.
research Mast cell deficient and neurokinin-1 receptor knockout mice are protected from stress-induced hair growth inhibition
Certain mice without specific receptors or mast cells don't lose hair from stress.
research Stress exposure modulates peptidergic innervation and degranulates mast cells in murine skin
Stress increases nerve fibers and immune cell activity in mouse skin, possibly worsening skin conditions.
research Hair growth inhibition by psychoemotional stress: a mouse model for neural mechanisms in hair growth control
Stress can stop hair growth in mice, and treatments can reverse this effect.
research Neuronal plasticity of the “brain–skin connection”: stress-triggered up-regulation of neuropeptides in dorsal root ganglia and skin via nerve growth factor-dependent pathways
Stress increases certain chemicals in the skin and nerves, which might worsen skin conditions.
research Foot shock stress prolongs the telogen stage of the spontaneous hair cycle in a non‐depilated mouse model
Stress in mice delays hair growth and treatments blocking substance P can partly reverse this effect.
research Telogen Effluvium: Is There a Need for a New Classification
The paper suggests improving diagnosis and treatment of telogen effluvium but does not recommend a new classification system.
