This review suggests that injectable platelet-rich fibrin therapy shows promise for improving hair density in androgenetic alopecia and enhancing facial skin texture and elasticity, but larger studies are needed to confirm its effectiveness.

This study found that hair with lower levels of keratin associated proteins reduced the foreign body response in mouse subcutaneous implant tests compared to hair with higher keratin levels.

This study found that the petroleum ether extract of Solanum nigrum may promote hair regrowth in testosterone-induced hair loss in rats, as indicated by increased follicle density and anagen/telogen ratio.

This review found that while platelet-rich plasma treatment significantly increased hair density compared to baseline in people with androgenetic alopecia, its effectiveness was not significant compared to placebo in most studies.

This study on diabetic rats reported that Ziziphus spina-christi ethanol leaf extract significantly reduced blood glucose levels and improved liver and kidney function, suggesting possible benefits in managing diabetes symptoms in this animal model.

This study found that an herbal extract from Marking nuts, when compared to a standard drug, effectively inhibited the dandruff-causing organism Malassezia furfur and promoted hair growth on mice, suggesting potential use for dandruff treatment and hair rejuvenation.

Platelet-rich plasma therapy may have benefits and is generally safe, but more research is needed to confirm its effectiveness and safety.

This review suggests that platelet-rich plasma therapy shows promise for androgenetic alopecia and may be effective for some alopecia areata and cicatricial alopecia cases, but more robust trials are needed.

This commentary discusses donor area alopecia resulting from follicular unit excision, noting that numerous small scars can lead to thinning in the donor area, and calls attention to this emerging issue.

This study found that topical application of Sinsun-yukza-hwan extract significantly increased hair density and thickness in a mouse alopecia model and enhanced expression of growth-related genes.

The April 2014 issue of "Fertility and Sterility" discussed various reproductive health topics, including hormone therapy benefits, sperm and genetic factors in male infertility, and the link between PCOS and diabetes.

This study concluded that while transected hair follicles can survive after transplantation in follicular unit extraction, their growth rate is unsatisfactory, and they are thinner than original follicles.

This article offers guidance for hair transplant surgeons on addressing old or poorly executed transplants, focusing on surgical precision and effective use of limited donor hair to enhance cosmetic outcomes.

This study found that Convolvulus arvensis ethanolic extract may promote hair growth and reduce hair loss in albino mice with testosterone-induced baldness by increasing follicular density and the anagen/telogen ratio.

This study found that platelet-rich plasma therapy was more effective in increasing hair count than topical 5% minoxidil lotion in men with androgenetic alopecia.

This meta-analysis reported that photobiomodulation therapy may improve hair density and stimulate hair growth in patients with androgenic alopecia compared to sham treatments, but larger studies are needed to confirm these findings.

Cyclosporin doesn't stop hair loss.

In this study, women with polycystic ovary syndrome showed adverse lipoprotein profile changes that increase cardiovascular risk, which were found to be more closely related to androgen levels than body weight.

This review discusses the use of platelet-rich plasma for treating female androgenetic alopecia, reporting that it shows high patient satisfaction and improved quality of life in affected women.

This study found that a 16-week dermal application of rice bran extract significantly increased hair density and diameter in male androgenic alopecia patients without causing adverse reactions.

In this systematic review, researchers found that nanotopical systems like nanoparticles and liposomes significantly improved hair density, thickness, and follicular regeneration markers in alopecia treatment, sometimes surpassing traditional therapies like topical minoxidil, though methodological limitations remain such as insufficient long-term clinical trials.

This paper highlights the need for a comprehensive red ginseng monograph to provide standardized information on its components, certified functionality, efficacy, action mechanisms, and safety, especially given its widespread use as a health functional food in South Korea and interest in its benefits worldwide.

In this study, oral administration of Crataegus pinnatifida extract was associated with hair growth promotion in mice by inducing anagen phase and enhancing cell signaling related to hair follicle development.

This study found that platelet-rich plasma significantly increased hair diameter in both men and women with androgenetic alopecia but improved hair density only in men.

This review discusses the role of scalp imaging techniques in trichology for researching drug delivery and toxicology, without presenting new clinical results.

This review concluded that LED-based photobiomodulation is generally safe and effective for certain dermatologic conditions, though consumer devices often show less efficacy compared to professional systems.

In this simulation study, higher cannabis exposure was associated with increased hair shedding severity and reduced follicular density, with greater effects observed in female-assigned profiles, but these associations are based on modeled data and not clinical observations.

This study developed a novel system that can automatically estimate hair loss parameters from images without expert input, reporting satisfactory results from testing on samples collected in Kolkata.
