St. John's wort skin oil may increase skin damage risk during radiotherapy.
research Trichodynia (Scalp Dysesthesia)
Many people with hair loss experience scalp pain known as trichodynia, but the causes are unclear and treatments vary.
research Cutaneous manifestations associated with substance use disorders
Skin issues can signal substance use, helping early detection and treatment.
research What factors play a role in unhealthy hair?
Environmental, chemical, mechanical, and personal health factors can all damage hair and contribute to hair loss or changes in hair quality.
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 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 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 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 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 Inhibitory effect of tianeptine on catagen induction in alopecia areata-like lesions induced by ultrasonic wave stress in mice
Tianeptine, an antidepressant, may prevent stress-induced hair loss in mice.
research The role of sleep in telogen effluvium and trichodynia: A commentary in the context of the current pandemic
Poor sleep during the pandemic may increase stress and worsen hair loss conditions.
research Reduced rates of substance use disorder in patients with alopecia: An all of us case-control study
Alopecia may lower the risk of substance use disorder.
research The synergistic effect of phototherapy and active substances on hair growth
Combining light therapy with certain substances improves hair growth in people with hair loss.
research Extractable substances from human hair: a discussion about the origin of the holes
Holes in mature hair are likely caused by the removal of substances during hair care.
research Characteristics of 60 adult chronic hair pullers
Most adult chronic hair pullers are women who started in their early teens, often have other mental health issues, and may pull hair due to underlying psychiatric conditions.
