This article reviews the differences between scarring and non-scarring alopecias and describes diagnostic methods but reports no new clinical findings.

The document concludes that doctors should monitor children's brain development when treating hemangiomas with interferon alfa and consider stopping the treatment if problems arise, while also exploring drugs that might counteract side effects.

In this study, researchers using QM/MM simulations identified key molecular motions and residue interactions in the enzyme SRD5A2 that significantly influence its catalytic efficiency, demonstrating that specific residues play critical roles in stabilizing transition states and reducing activation barriers.

This study found that a specific macrophage subpopulation in the dermis helps maintain hair follicle stem cell quiescence through cytokine-mediated signaling.

In this laboratory study, ASC-conditioned medium showed higher therapeutic potential than extracellular vesicles alone in reducing inflammation and catabolic activity in human chondrocytes with an osteoarthritis phenotype, highlighting its possible use in osteoarthritis management.

This case report describes a serious complication of follicular unit extraction, where donor-site necrosis led to cicatricial alopecia, but was successfully treated with two-stage surgery using tissue expanders.

This study observed that certain herbal extracts may promote hair growth and inhibit hair loss in cell lines by affecting specific protein expressions similarly to minoxidil.

This study found that para rubber seed oil, rich in specific fatty acids, effectively protected human epidermal coculture cells from UV-induced damage by reducing inflammatory markers and enzymes linked to photoaging, indicating its potential as a safe and innovative photoaging treatment.

In this study, researchers developed an innovative training model using oranges to practice designing the scalp's parietal whorl for hair transplantation. They reported that a density of 40-50 follicular units per cm² achieved better results, aiding surgeons in improving their technique.

Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.

This study observed mycobacterial infection with M. xenopi in a pet ferret, noting its resistance to doxycycline, and highlighted the potential zoonotic transmission risk associated with such infections.

This study found that a 3 mm margin around the prostate CTV may be adequate if accompanied by frequent imaging, but superior-inferior displacements were notably greater than in other directions.

This study found that a 0.5-mm microneedle depth was more effective than 0.3 mm for increasing hair density in AGA patients treated with a topical growth factor cocktail.

In this study, researchers developed a biomimetic anti-inflammatory nanosystem (MM-CEP/NLCs) that significantly reduced the severity of acute lung injury in vivo by targeting and accumulating in lung inflammation sites, showcasing its potential for treating inflammation.

In this study, MMF plus prednisolone was found to induce remission in 81% of patients with proliferative lupus nephritis, with fewer adverse effects such as alopecia and amenorrhea compared to CYC plus prednisolone, despite similar overall remission rates.

This study found that microneedling with longer needles (3 mm) showed better hair regrowth in dogs with hair cycle arrest, although most experienced recurrent hair loss during follow-up. Some dogs also developed minor, temporary itching.

This study found that combining microneedling at depths of 0.5 mm or 1 mm with minoxidil tincture significantly improved hair density and diameter in men with androgenetic alopecia compared to minoxidil alone, although the deeper microneedling also led to higher adverse reactions.

This study found that commercially available dyes penetrate up to 1.2 mm into human skin, with Indocyanine Green binding to cell proteins and showing a shift in absorption peak.

This study found that procyanidins effectively alleviate neuropathic pain in mice by significantly inhibiting MMP-9/2 activity.

This study reported that a single treatment using macrofocused ultrasound energy with a 2 mm transducer significantly reduced pore count, pore volume, and pore index in 34 Thai subjects with enlarged facial pores over a 6-month period, with no adverse events observed.

This study measured the lengths and depths of different portions of occipital scalp hair follicles and suggested cutting below 1 mm for hair regeneration procedures to avoid damaging the bulge zone.

In this study, more than 25% of children experienced axial length shortening greater than 0.05 mm/year following repeated low-level red-light therapy.

In this study, microneedling with a depth of 0.6 mm, alongside minoxidil, significantly improved hair count and thickness in patients with androgenetic alopecia compared to minoxidil alone, and was more beneficial than a 1.2 mm depth.

A scalp biopsy is essential for accurately diagnosing alopecia, with a 4-mm punch biopsy sectioned horizontally being the recommended technique according to this study.

This study reports the demonstration of electromagnetic energy transfer from human blood tissue to a human hair follicle through a 1 mm glass barrier, using in vitro experiments.

This study investigated the effects of GFC with FGF5s and NMN at a depth of 0.8 mm using a microneedle for treating hair loss, but the abstract provides no measurable results.

This study observed that in primary extramammary Paget disease, carcinoma commonly spreads to significant depths along hair follicles and eccrine ducts, with a maximal depth of 3.6 mm.

This study investigated a gelatin-based bioink for 3D bioprinting a simplified skin model, finding that a formulation with 15% gelatin and 150 mM calcium chloride supported a homogeneous distribution of viable cells over 14 days, showing promise for drug evaluation applications.

In this study, researchers developed a new classification system for anterior hairline types among Asian males without androgenetic alopecia, finding MM, RM, and ML to be the most common types.

This study presented a hair harvesting robot with an advanced end-effector that improves accuracy and efficiency for Follicular Unit Extraction, showing a precision of 0.014 mm.
