research Androgen Biosynthesis and Gene Defects
Gene mutations can cause problems in male genital development.
research Basics of Hormonal Contraception
Hormonal contraceptives are effective for teens but require careful consideration of side effects and individual health.
research Chronic Restraint Stress Inhibits Hair Growth via Substance P Mediated by Reactive Oxygen Species in Mice
Chronic stress can cause hair loss by increasing oxidative stress, but antioxidants may help.
research Sexual Hormones in Human Skin
Human skin makes sexual hormones that affect hair growth, skin health, and healing; too much can cause acne and hair loss, while treatments can manage these conditions.
research Interrelation of immunity and tissue repair or regeneration
The immune system plays a key role in tissue repair, affecting both healing quality and regenerative ability.
research Alopecia areata: A multifactorial autoimmune condition
Alopecia areata is an autoimmune disease causing patchy hair loss, often with other autoimmune disorders, but its exact causes are unknown.
research The Circadian Clock in Skin
The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.
research Androgen actions on the human hair follicle: perspectives
Androgens have complex effects on hair growth, promoting it in some areas but causing hair loss in others, and our understanding of this is still evolving.
research Thyroid Hormones Directly Alter Human Hair Follicle Functions: Anagen Prolongation and Stimulation of Both Hair Matrix Keratinocyte Proliferation and Hair Pigmentation
Thyroid hormones help hair grow, reduce hair loss, and increase hair pigment.
research The blastema and epimorphic regeneration in mammals
Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.
research The Dark Side of 5α-Reductase Inhibitors' Therapy: Sexual Dysfunction, High Gleason Grade Prostate Cancer and Depression
5α-reductase inhibitors can cause sexual problems, higher risk of aggressive prostate cancer, and depression.
