The researchers reported that a novel leave-on treatment containing caffeine, niacinamide, panthenol, dimethicone, and an acrylate polymer significantly increased the diameter and improved the mechanical properties of scalp hair fibers, suggesting it may help mitigate thinning hair.

This study found that white wax and its extract may promote hair growth in a mouse model of androgenetic alopecia by inhibiting 5α-reductase activity and increasing cell proliferation, with efficacy surpassing finasteride.

This study found that a marine-extract dietary supplement significantly reduced hair shedding and increased hair diameter in premenopausal women with subclinical hair thinning or hair loss after 6 months of use.

This review examines melatonin's potential effects on human skin and hair follicle pigmentation, highlighting the need to confirm findings from cell cultures in physiological tissue contexts.

In this study, topical minoxidil did not show an antiandrogenic effect on androgen-dependent cutaneous structures in the golden Syrian hamster, suggesting it likely does not have this role in humans either.

Trichoscopy helps diagnose and manage different types of hair loss effectively.

Minoxidil effectively treats hair loss, works better for women, and requires consistent use.

This case series reports the experience of using oral minoxidil at 1.25 mg/day in 32 patients with male androgenetic alopecia, noting both therapeutic effects and potential adverse reactions.

This study found that individuals with protein-calorie malnutrition, especially those with kwashiorkor, required significantly less force to pluck hair compared to well-nourished patients.

This case study reports that combining platelet-rich plasma with intradermal triamcinolone acetonide improved hair regrowth and fiber diameter in one patient with alopecia areata compared to triamcinolone alone.

This study reported that fibrosing alopecia in a pattern distribution can occur in patients of color, with clinical and histopathological features allowing for an accurate differential diagnosis.

This study observed no significant improvement of mesotherapy over 5% topical minoxidil for male androgenic alopecia, despite a small increase in hair shaft diameter variation with mesotherapy.

This study investigated the effects of the herbal formulation DA-5512 on hair growth, finding that it significantly promotes dermal papilla cell proliferation and stimulates hair growth in mice while showing efficacy and safety in human trials compared to placebo and minoxidil (3%).

This study found that topical minoxidil 5% gel and spironolactone 1% gel were both effective treatments for androgenetic alopecia, with a combination of both providing the best clinical response and achieving 100% effectiveness among participants.

This study found that 1,550-nm Er:Glass fractional laser treatment increased hair density and shaft diameter in patients with androgenetic alopecia, but did not up-regulate Wnt10A and IGF-1 mRNA expression.

This study found that melatonin combined with bromocryptine treatment in Spanish goats increased secondary hair follicle numbers and extended the cashmere growth phase during spring.

In this study, echocardiographic measures of cardiac function in women with polycystic ovary syndrome were found to be similar to those of healthy women.

The authors concluded that trichoscopy is a valuable noninvasive tool for diagnosing and monitoring nonscarring alopecia, aiding in the identification of new hair signs in difficult cases.

This study found that IPL hair reduction led to significant decreases in hair count and thickness by promoting hair follicle miniaturization, increased telogen phase, and reduced cell proliferation.

This study suggests that early initiation of treatment in fibrosing alopecia in a pattern distribution may lead to a more favorable outcome, as evident in some patients experiencing arrested disease progression and hair regrowth.

This study indicates that sheep prenatally androgenized with testosterone show wool fiber diameter changes that parallel the increased hair diameter in women with polycystic ovary syndrome.

Minoxidil solution applied twice daily improved hair growth in patients with Woolly Hair/Hypotrichosis due to LIPH gene issues, with mild side effects.

This study found that parenteral administration of cyproterone acetate was more effective than high-dose oral treatment in reducing facial hair diameter and improving dermatological parameters in patients with severe hirsutism, despite similar androgen suppression.

This article reviews various types of alopecia, their diagnostic features, and patterns, but presents no new clinical findings; the authors discuss multiple mechanisms and classification challenges.

In this study, QR678® and QR678 Neo® injections significantly improved hair density and thickness in women with PCOS-related alopecia over eight sessions, with effects lasting over a year.

This study found that applying 2% Minoxidil lotion twice daily for four months improved hair diameter and density in individuals with eyebrow hypotrichosis, suggesting it is an effective and well-tolerated treatment; mild side effects like itching and burning were observed in 22.72% of participants.

Hamilton scale imprecise, hair shaft diameter decreases, stem cell transplant regrows hair, ECP ineffective for alopecia areata universalis.

This study reports that quantitative trichoscopy, while noninvasive and convenient, provides less accurate hair density data compared to invasive histopathologic examination, which was demonstrated in a sample of adult Chinese individuals without alopecia.

This study examined 15 female patients with hypothyroidism to investigate the characterization of their alopecia and ruled out other causes, using medical histories, and clinical, trichoscopic, and histologic findings.

This review discusses various hair loss treatments, such as stem cell therapy, laser therapies, and mesotherapy, emphasizing their potential and limitations while highlighting the need for further research to address genetic factors in hair loss.
