This study found that PGF2alpha analogues and PGE2 stimulated hair follicle activity in mice, with PGF2alpha analogues also linked to potential side effects like poliosis when used as eye treatments.

In this laboratory study, researchers found that a methanol extract of peach kernel improved the growth and viability of human hair follicle dermal papilla cells, suggesting its potential efficacy for hair growth and care through cell proliferation and signaling pathways activation.

This study found that a hair-coating polyphenol complex significantly enhanced the mechanical strength, UV protection, and antistatic properties of damaged hair, suggesting potential benefits for hair treatment.

This article introduces the Progressive Loss (PL) Scale, aimed at helping physicians communicate the long-term cosmetic risks of hair restoration surgery to patients.

This study suggests that Ptprq in the hair bundles may exist as multiple isoforms that are differentially expressed throughout development and affect the organization of stereocilia in the chick inner ear.

This study found that combining a thulium laser with intra-perifollicular PDRN injections significantly improved hair thickness but not hair counts compared to mesotherapy and PDRN in patients with pattern hair loss.

In this study, a 26-year-old woman with polycystic ovarian disease and advanced hair loss (Ludwig Grade III) showed reduced hair shedding and improved hair density after four sessions of platelet-rich plasma combined with microneedling, with no reported adverse effects.

In this study, phosphorus starvation in Arabidopsis thaliana roots strongly affected stress-induced cytosolic calcium ion modulations, which were reversible with phosphorus resupply.

This case series observed that macular changes from popper use can resolve completely after cessation, even in individuals with chronic use.

This study found that inhibiting prolactin secretion during the telogen phase can reduce the number of activated secondary hair follicles and the width of hair bulbs.

This study observed that POMP is strongly expressed in the root sheath hair follicles of Liaoning Cashmere goats and its expression can be regulated by certain factors, which may influence cashmere growth.

This study identified peripheral myeloid cells as the earliest dysregulated immune cells in PINK1 KO mice with Parkinson’s-like symptoms following intestinal infections, suggesting that PINK1 regulates gut immune functions linked to early Parkinson’s disease mechanisms.

This reported case of lichen planopilaris in siblings suggests a potential genetic predisposition, supporting the hypothesis of inherited susceptibility in this condition.

In this study, ALP knockdown significantly impaired the hair follicle-inducing capacity of human dermal papilla spheres, highlighting a critical role for ALP in hair follicle neogenesis.

This study developed a biobased copolymer called SELP::KP, showing improved hair strength, elasticity, and conditioning properties while being a safer alternative to conventional chemical treatments, based on application to human hair in a laboratory setting.

This study demonstrated that using lead-doped keratin film as a calibration standard allows for accurate tracking of lead distribution along hair strands, revealing different exposure patterns among workers in a battery manufacturing factory in Thailand.

This study suggests that KRTAP2-3 may serve as a novel biomarker to identify cells in the polyaneuploid cancer cell state, which is linked to therapy resistance and poor prognosis in prostate cancer.

This study shows that NIPP1 deficiency in mouse epidermis leads to hyperproliferation, hair loss, and chronic skin inflammation, which can be partially alleviated by dexamethasone treatment.

In this pilot study, PDLLA scalp microinjections showed improvement in physician-rated Global Aesthetic Improvement Scale scores over 12-24 weeks for 90% of patients with non-scarring alopecia, with no serious adverse events reported, although findings remain preliminary due to methodological limitations.

This review analyzes PDRN's molecular mechanisms and therapeutic applications in anti-aging dermatology but reports no new clinical results, highlighting the need for more standardized protocols and long-term evaluations.

This article examines the PCPT study on whether daily finasteride can reduce prostate cancer incidence, describing its methodology and findings but reporting no new clinical results.

This review discusses the application of PRP therapy in pediatric settings and highlights the current lack of sufficient data for its widespread clinical use.

This study found that elevated 1-hour plasma glucose in women with PCOS was associated with increased risk of metabolic disorders and gestational diabetes, indicating it may be a useful marker for adverse metabolic status.

This case study reported on a 49-year-old male with muscle weakness and low potassium levels, suggesting a diagnosis of thyrotoxic hypokalemic periodic paralysis.

This study reports that controlled release PRP therapy using dalteparin and protamine micro-particles may be effective for hair growth and skin rejuvenation in women.

This study found that in a large cohort of chronic kidney disease patients, nonprogression or regression of the disease was more common than progression or kidney failure, especially with advancing age.

This study found a significant association between prolactin levels and polycystic ovary syndrome (PCOS), recommending precise investigation of prolactin levels in PCOS patients to identify causes of hyperprolactinemia.

This study reports that the peptide GPIGS, found in Bacillus sp. M18 conditioned medium, may promote hair growth through the PI-3K/Akt pathway and accelerate hair regrowth in mice.

This study found that 21 out of 39 patients with alopecia areata experienced more than 50% hair regrowth after six months of DPCP treatment, with better outcomes observed in those treated at 3-week intervals compared to weekly intervals.

In this study, a 26-year-old woman with polycystic ovarian disease and severe hair loss showed reduced hair shedding and improved hair density following four sessions of platelet-rich plasma combined with microneedling, with no adverse effects reported.
