research The placebo effect and randomized trials: analysis of conventional medicine
This review examines the placebo response in conditions such as allergies and weight loss, highlighting its significance in both conventional and alternative medicine randomized trials, without reporting any new results.
research Placebo‐controlled dose‐effect studies with topical minoxidil 2% or 5% in male‐patterned hair loss treated with oral finasteride employing an analytical and exhaustive study protocol
This study reported that combined oral finasteride and topical 5% minoxidil treatment in men with male-pattern hair loss improved hair growth by initiating anagen in pre-existing but deficient follicles, yet the growth rates remained unchanged and did not normalize hair productivity.
research The Effect of Platelet-Rich Plasma in Hair Regrowth: A Randomized Placebo-Controlled Trial
This study found that platelet-rich plasma injections significantly increased hair count and density in patients with male pattern hair loss without major side effects, suggesting it may be a safe and effective treatment option.
research The effect of latanoprost 0.005% solution in the management of scalp alopecia areata, a randomized double‐blind placebo‐controlled trial
This study found that using topical latanoprost 0.005% solution significantly increased hair density and regrowth in patients with scalp alopecia areata over 12 weeks, although it did not significantly reduce hair loss area compared to the placebo.
research A randomized placebo-controlled study on the effects of pioglitazone on cortisol metabolism in polycystic ovary syndrome
In this study, pioglitazone treatment in insulin-resistant PCOS patients decreased relative 5alpha-reductase activity without significantly affecting cortisol levels or urinary cortisol excretion.
research The effect of platelet rich plasma (PRP) in the hair re-growth: A randomized placebo-controlled trial
research The effects of ginger (Zingiber officinale) supplementation on the hormonal profile, hirsutism, amenorrhea, dysmenorrhea, and hair loss in women with polycystic ovary syndrome: a randomized double-blind, placebo-controlled trial
In this study of women with polycystic ovary syndrome, 12 weeks of daily ginger supplementation significantly reduced total testosterone and improved menstrual irregularities compared to placebo, suggesting potential as a natural therapeutic approach, although larger studies are needed.
research The effect of autologous activated platelet-rich plasma injection on female pattern hair loss: A randomized placebo-controlled study
This study found that platelet-rich plasma injections significantly improved hair density, thickness, and patient satisfaction in women with female pattern hair loss compared to a placebo.
research A Randomized Double-Blind Placebo-Controlled Pilot Trial on the Effects of Testosterone Undecanoate Plus Dutasteride or Placebo on Muscle Strength, Body Composition, and Metabolic Profile in Transmen
This study demonstrated that testosterone treatment increases muscle strength and alters body composition in transmen, and the addition of dutasteride does not impair these anabolic effects.
research The effects of spinach-derived thylakoid supplementation in combination with calorie restriction on anthropometric parameters and metabolic profiles in obese women with polycystic ovary syndrome: a randomized, double-blind, placebo-controlled clinical trial
This study found that spinach-derived thylakoid supplementation, combined with a calorie-restricted diet, led to more significant improvements in weight loss and insulin sensitivity in obese women with PCOS than calorie restriction alone.
