This article discusses the benefits of herbal hair serum for hair growth and scalp health but reports no new clinical results.

This study found that lower serum testosterone levels were significantly associated with an increased prevalence of kidney stones in men over 40, but not in those aged 20–40.

In this laboratory study, researchers found that human platelet-rich plasma (hPRP) significantly improved the proliferation and hair-inductive capacity of human dermal papilla cells (hDPCs) compared to fetal bovine serum, suggesting hPRP as a potential substitute for FBS in expanding hDPCs for clinical hair regeneration therapies.

In this study, applying deer antler velvet extract-loaded niosomes and microspicules serum to the scalp significantly improved hair growth, melanin content, and skin hydration over 14 to 30 days without causing skin irritation.

This review highlights the potential of flaxseed as a natural hair care ingredient, noting its moisturizing, strengthening, and nutritional properties that may improve hair health and texture, though more clinical studies are needed to confirm these benefits.

In this review, the authors provide a comprehensive overview of Equisetum arvense (horsetail) as a promising natural ingredient in cosmetics, highlighting its antioxidant, anti-aging, anti-inflammatory, and wound-healing properties, while also noting challenges related to standardization and clinical validation.

This review examines the use of horsetail extract in cosmetics, highlighting its antioxidant, anti-aging, and skin-enhancing properties due to its rich phytochemical content, but notes that standardization and clinical validation remain challenges.

This study found that flaxseed-olive oil-based herbal formulations may be effective and multifunctional for scalp protection and hair health, showing strong antioxidant and antibacterial properties.

This study found that the expression of the protein SOX2 is associated with the potential for beige adipocyte formation and adipocyte plasticity in both human and mouse models.

In this exploratory randomized controlled trial, participants using a combination of Centella asiatica-derived extracellular vesicles with recombinant growth factors showed significant improvements in hair thickness, density, length, and reduced hair loss and scalp sebum content after 56 days, compared to placebo.

This study found that a hair tonic containing 10% mesenchymal stem cell secretome significantly increased hair density in volunteers with alopecia after eight weeks, suggesting its potential as an effective treatment option for hair growth stimulation.

This study found that a hair tonic containing 2% green tea extract significantly reduced scalp sebum in 20 volunteers over 28 days without causing skin irritation, suggesting its effectiveness and safety for managing scalp greasiness.

In this study involving Japanese women, researchers found that higher scalp oil levels were linked to weaker hair structure and increased scalp inflammation, suggesting that plant-derived compounds might mitigate these effects by reducing inflammation at the genetic level.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

In this systematic review, an increase in hemoglobin and hematocrit was associated with testosterone therapy, especially within the first year, and factors like serum testosterone levels and therapy specifics were linked to erythrocytosis development, highlighting the need for further research to guide clinical practice.

This study investigated various synthesized 5-reductase inhibitors and found that compound 6 had the highest anti-androgenic activity and receptor affinity compared to finasteride, showing potential due to its improved efficacy and bioavailability for further research in treating lower urinary tract symptoms.

Retinoids are effective for acne but can cause serious side effects.

This study investigated the sub-acute toxicity of Eclipta alba extract in Wistar albino rats, finding generally comparable hematological and biochemical parameters to controls, but noted mild morphological liver and kidney changes at the highest dose, highlighting a key area for further safety research.

This study found that Ajuga reptans leaf and root extracts, when incorporated into cosmetic products, improved skin hydration, elasticity, pore size, hyperpigmentation, and wrinkle depth.

This article discusses the mechanisms by which Cutibacterium acnes contributes to acne vulgaris and mentions potential triggers like UV light and tobacco, but it reports no new clinical results.

This study found that domestic and imported finasteride tablets were bioequivalent in terms of their pharmacokinetic parameters and relative bioavailability in human volunteers.

Topical finasteride is promising for hair loss with minimal side effects but needs more research and approval.

This study found that 2% ketoconazole shampoo improved hair density and anagen follicle proportion in androgenic alopecia similarly to minoxidil treatment, suggesting a potential role for Malassezia in inflammation.

This study found that applying a topical scalp essence with Centella asiatica extracellular vesicles and growth factors significantly improved scalp health and hair growth compared to a placebo after 56 days.

This study found that the peptide derivative beta-Ala-Pro-Dab-NHbenzyl may reduce wrinkles and sebum production in human skin by inhibiting dipeptidyl peptidase 4, suggesting potential for acne and skin inflammation treatment.

This study reported that BRL 7660 significantly reduced sebum secretion and acne symptoms in human studies with topical administration, but the placebo effect and commercial pressures halted further investigations.

This review highlights that polyherbal anti-dandruff shampoos, which use combinations of medicinal plants like neem and aloe vera, are promising alternatives to conventional shampoos due to their multi-targeted therapeutic actions and fewer adverse effects, offering a safer and holistic approach to managing dandruff.

This study found that oral contraceptives, particularly those combining ethinyl estradiol with progestins like drospirenone and cyproterone acetate, are effective in treating androgen-related skin conditions such as acne, hirsutism, and androgenetic alopecia by reducing excess androgens and sebum production.

Hair grows like a crystal at a solid-liquid interface without cell division.
