This study found that deslorelin may promote hair regrowth in intact male dogs with hair cycle arrest, but had no effect on neutered females.

This study reports an unusual finding of plucked anagen hairs with intact hair papilla and connective tissue sheath in various scalp disorders, suggesting further documentation is needed.

This study found that 17α‐estradiol increases aromatase activity in female hair follicles, which may explain its beneficial effects in treating androgenetic alopecia.

This study observed that in privately owned, intact cats, male cats exhibited significantly higher long-term hair cortisol concentrations compared to females, while environmental and behavioral factors did not significantly impact cortisol levels, suggesting individual traits may influence stress markers more than external factors.

This study suggests that keratin 15 and Id3 proteins play distinct roles in epithelial and dermal cell activities during the regeneration stages of rat vibrissae hair follicles.

This study found that proteolytic activities in murine skin vary with hair cycle stages, with significant collagenase activity during the early anagen phase.

In this study, researchers identified gremilin-2 as a highly specific gene to the dermal sheath cup, suggesting it plays a key role in maintaining its properties.

In this study, mouse sebaceous glands were found to require nerves for growth during active hair cycles, suggesting a nerve-dependent sebaceous gland cycle coordinated with hair growth.

A method was developed to grow hair follicles in a lab for research on hair growth and health.

In this study, a single deslorelin acetate implant led to substantial and sustained hair regrowth in two sexually intact male keeshonden with hair cycle arrest.

In this study, researchers developed a novel periodate oxidation method for extracting keratin micro-units from waste hair and feathers, achieving yields of 31.28% and 20.64% respectively, enhancing the stability of oil-in-water emulsions and suggesting potential for sustainable biomaterial production.

Topical thyroid hormones may boost hair growth.

This study concluded that the inner root sheath inhibits the expression of certain differentiation markers in hair bulbs, with calcium-induced changes paralleling those seen in hair follicle mid-segments.

This study introduced hair capacitance mapping as a promising technique for assessing hair surface moisture dynamics, revealing that weathered hair loses moisture more quickly than intact hair.

This article describes a modified follicular unit extraction technique using a reverse rake scalp elevator, which may reduce follicular transection rates in hair transplantation from the lower occipital donor region.

This study reported that a treatment serum containing ingredient blends with panthenol, licorice extract, and red clover extract significantly improved hair volume, scalp coverage, and reduced hair breakage over 6 months in individuals with thinning or damaged hair.

Deslorelin can help regrow hair in most intact male dogs with alopecia.

An intact skin barrier is crucial to prevent infection in cases of tether-induced tenosynovitis.

In this study, rat vibrissa follicles transplanted into mice demonstrated survival, partial sympathetic nerve reinnervation, and increased norepinephrine levels 37 days post-implantation, suggesting potential for hair growth despite not returning to normal nerve function.

This article reviews recent hair restoration techniques evaluated in case studies at WHS/ISHRS workshops but reports no new clinical results, highlighting the need for further research with larger study groups.

This study found that bimatoprost, when applied daily at a 0.03% concentration, promoted significant hair growth in C57/black 6 mice, including earlier and faster regrowth of shaved fur.

This study demonstrated that intact adult human dermal papillae can induce hair growth when implanted into mouse hair follicles, highlighting their potential for advancing hair follicle biology and therapeutic approaches.

This study found that intact pilosebaceous units were more effective than truncated hair follicles at regenerating a multilayered epidermis in a de-epidermalized dermis in vitro.

This study demonstrated that human hair shafts can be anatomically separated to obtain intact micron and nano keratin filaments using solvents like performic acid and urea.

This study reported that X-ray microscopy provides more intact images of hair's internal structure compared to transmission electron microscopy, particularly for observing fine details like cuticle coarsening and cortex cracks.

This study reports that a new DART-HRMS method can effectively analyze intact hair for drug use timelines, with cocaine detection aligning with forensic standards and identifying multiple drugs from high-resolution data.

This study found that cyclophosphamide-induced hair follicle damage in C3H mice could be remodelled into intact anagen hair follicles with topical cyclosporin A, especially in anagen IV stage follicles.

This article discusses the concept of "Follicular Units" in hair anatomy and suggests that maintaining intact follicular units may enhance the survival and growth of hair grafts, but reports no new clinical results.

In this study, researchers observed that more hairs are extracted from the follicle with intact root bulbs than breakage occurring along the fiber in treated versus untreated hair.
