research Original papers A study on efficacy of 308 nm excimer light therapy in alopecia areata
308 nm excimer light therapy may help hair regrowth in alopecia areata with delayed results and no serious side effects.
research Body dynamics, social meaning-making, and scale heterogeneity: re-considering contextualization cues and language as mixed-mode semiosis
Confinement in farrowing crates doesn't increase chronic stress in sows, but hair cortisol measurements may not reliably indicate stress due to hair growth variations.
research Bisphenol-A antagonizes the rapidly modulating effect of DHT on spinogenesis and long-term potentiation of hippocampal neurons
Bisphenol-A (BPA) increases connections between brain cells and boosts their activity, but it blocks the effects of a male hormone on brain cell plasticity.
research In vitro effects of testosterone, dihydrotestosterone and estradiol on cell growth of human hair bulb papilla cells and hair root sheath fibroblasts.
High levels of testosterone and dihydrotestosterone inhibit hair cell growth, while high levels of estradiol promote it.
research Phosphorus-induced change in root hair growth is associated with IAA accumulation in walnut
Phosphorus affects walnut root hair growth by altering auxin levels.
research Evaluation of wavelength-dependent hair growth effects on low-level laser therapy: an experimental animal study
The 830-nm wavelength was most effective at promoting hair growth in rats using low-level laser therapy.
research [Dose/effect correlation in topical minoxidil therapy of androgenic alopecia].
More minoxidil applied topically leads to better hair growth in male pattern baldness.
research Development of an improved method to estimate the days of continuous drug ingestion, based on the micro‐segmental hair analysis
Researchers improved a method to more accurately estimate when and how long a drug was taken using hair analysis.
research Time Perspective as a Mediator of Depressive Symptoms in Patients with Polycystic Ovary Syndrome
Helping PCOS patients focus on hope and control can reduce depression.
research Laser Diodo 800nm and Hirsutism in Darker Skinned Patients: Our Experience on 552 Women
The laser treatment effectively reduced hair growth in women with hirsutism, with temporary side effects.
research Effects of cepharanthine and minoxidil on proliferation, differentiation and keratinization of cultured cells from the murine hair apparatus
Cepharanthine and minoxidil promote cell growth and delay hair cell maturation.
research 054 Post Finasteride Syndrome: Guess Who-Demographics from FDA Database
Younger people (median age 35) experience more PFS-like symptoms with 1mg finasteride; more research needed.
