This study found that using intraoperative platelet-rich plasma in follicular unit extraction hair transplantation significantly improved graft survival, accelerated hair regrowth, and increased patient satisfaction compared to the procedure without PRP.

This study operationalizes a four-step workflow for selecting donor hair for capsule extensions, translating surgical trichology insights into an extension-specific protocol to enhance natural hair optics and biomechanics, suitable for premium extension services.

GFC is more effective than PRP for treating hair loss.

In this study, microneedling followed by topical 2% chitosan significantly improved hair growth parameters in patients with androgenetic alopecia, comparable to results with 5% minoxidil, but a small sample size limits definitive conclusions on their relative efficacy.

This study explored the effects of TTFE on male androgenic alopecia, finding that topical application increased hair density, follicular diameter, and scalp hydration while reducing water loss and sebum production in a 12-week trial.

This study found distinct sex-based differences in the microscopic characteristics of scalp hair among a Nigerian population, providing valuable forensic data specific to this group.

The researchers reported that one-third of women with female pattern hair loss in their study had occipital region involvement, which is important for diagnosing and planning treatment, including hair restoration surgery, as the occipital region is often used as a normal reference.

In this literature review, researchers found evidence that topical melatonin may improve scalp hair growth, density, and thickness in patients with androgenetic alopecia, especially in men.

This chapter reviews the potential of adipose-derived stem cells for skin aging and hair loss treatments but reports no new experimental results; the authors highlight these stem cells as a promising regenerative resource.

Hair health is influenced by genetics, aging, and environmental factors, with proper care needed to maintain it.

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.

In this randomized trial, a solid shampoo formulated with plant extracts was more effective than placebo in improving androgenetic alopecia and reducing hair cortisol and DHT concentrations in men.

This study found that QR678 Neo® significantly enhanced hair regrowth, density, and shaft diameter in males with advanced androgenetic alopecia undergoing hair transplant surgery, compared to a conventional method, making it a promising adjunct treatment option.

In this study, low-level laser therapy showed no statistically significant improvements in hair growth measures, despite some patients experiencing increases in terminal hairs and shaft diameter.

In this study, adults with mild-to-moderate hair damage taking GPVGPS Collagen® daily for 24 weeks showed significant improvements in hair luster, strength, thickness, and density compared to placebo, with no safety concerns reported.

This article proposes a methodology for selecting hair extension technology that aligns with natural hair structure and aesthetic goals, suggesting the best results are achieved by matching technique to hair's mechanical capacity.

This study describes a patient with Rothmund–Thomson syndrome-like symptoms who displayed hair improvement after combination therapy, despite carrying an ANAPC1 gene variant of uncertain significance.

In this study, Eremochloa ophiuroides-derived fractions were found to significantly promote hair regrowth in a mouse model, demonstrating effects comparable to minoxidil and suggesting potential as natural hair growth agents through modulation of follicular activation markers and growth-regulatory factors.

This study found that a polyherbal hair serum improved hair density and shaft quality while being safe and cosmetically acceptable.

In this study, researchers developed and tested a polyherbal hair serum containing several plant extracts, demonstrating its stability, safety, and effectiveness in promoting hair growth and improving hair quality, providing support for natural alternatives to synthetic hair care products.

This review explores the evaluation methods and biological parameters involved in hair growth assessment, highlighting their distinct applications and advantages, but presents no new clinical findings.

This study found that oral minoxidil improved hair density in women experiencing late alopecia due to chemotherapy and/or endocrine therapy, with 74% showing clinical improvement and statistically significant increases in hair shaft density reported in those assessed with trichoscopy.

This study concluded that stromal vascular fraction and topical minoxidil both improved hair characteristics in male and female patients with androgenetic alopecia, but SVF offered a more satisfactory treatment experience.

In this study, 675 nm laser treatment significantly improved hair density and reduced miniaturization in both male and female patients with alopecia androgenetica, showing promising results without side effects after 10 sessions.

Minoxidil solution and foam both increase hair growth, but the solution works better than the foam.

In this study, personalized PRP therapy significantly increased hair density and diameter in a patient with androgenetic alopecia, highlighting its potential benefit but emphasizing the need for broader clinical trials.

In this study, PRP-derived exosomes significantly outperformed minoxidil in promoting hair regeneration in a murine model of androgenetic alopecia, with the combination of both treatments showing enhanced follicular regeneration and increased markers of tissue proliferation and Wnt signaling pathway activity.

This review article evaluates new treatment techniques for androgenetic alopecia, including low-level laser therapy, platelet-rich plasma therapy, microneedling, and topical growth factors and peptides, reporting positive outcomes such as hair regrowth and improved hair density and thickness.

This pilot study found that Optical Coherence Tomography can non-invasively resolve hair follicle density and hair shaft and follicle diameters in patients at varying stages of hair loss.

In this study, intradermal injections of QR678 were found to significantly reduce hair fall in men with androgenetic alopecia over 6 months, with superior improvements in hair density and thickness compared to PRP.
