August 2015 in “MOJ proteomics & bioinformatics” This study suggests that epithelial-derived pop-up keratinocytes (ePUKs) may improve regenerative medicine applications due to their specific phenotype and increased expression of proteins involved in regulating cellular movement and wound healing.
This study found that a combined intake of enzyme food and collagen significantly improved various aspects of hair health in middle-aged women compared to taking either supplement alone or none.
September 2014 in “Daehan miyong hakoeji” Adding 2% glycerin or hyaluronic acid to permanent wave treatments reduces hair damage, with hyaluronic acid being more effective.
This study found that oxidized hair undergoes time-related structural changes, resulting in improved thermal and mechanical stability over several months after moderate or intense oxidative treatments.
This study found that applying hair conditioner during a permanent wave process in the middle rather than early or late improves tensile strength, hydration, and maintains healthier hair cuticle structure.
January 2012 in “Human health handbooks” This review discusses the application of low-level light therapy for hair loss treatment, particularly androgenetic alopecia, and reports no new clinical results; the authors suggest consideration of light source characteristics and potential pros and cons.
January 2012 in “Jounal of The Korean Society of cosmetology” Applying conditioner mid-treatment reduces hair damage during perms.
January 2012 in “한국미용학회지” In this study, applying hair conditioner during the middle of a permanent wave operation resulted in better tensile strength, hydration, and cuticle health compared to other application times.
September 2011 in “Daehan miyong hakoeji” Henna orange powder, especially with alkali, protects and colors hair better than oxidizing colorants.
December 2010 in “Journal of Oriental Medicine” This study found that shampoos containing extracts from black bean, wheat, and rice bran enhanced hair growth activity and improved the physical properties of aged hair in laboratory models.
February 2010 in “Acta Obstetricia et Gynecologica Scandinavica” This collection of articles in AOGS includes findings on tetranectin as a possible prognostic marker for advanced ovarian cancer, and the effectiveness of tension-free vaginal tape for recurrent stress urinary incontinence.
January 2010 in “DR-NTU (Nanyang Technological University)” This study found that exposure to chlorine significantly reduced tensile properties in human hair compared to normal, while dyeing only affected some properties but not all.
May 2009 in “International Journal of Cosmetic Science” In this study, permanent waving treatments, especially those using lotion B and repeated procedures, were found to significantly damage hair protein content and physical properties.
January 2008 in “대한미용학회지” This study reports that prolonged UV irradiation causes progressive damage to the hair's keratin structure, leading to increased surface roughness, cuticle destruction, and decreased tensile strength in young women’s hair.
Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.
March 2005 in “Journal of the American Academy of Dermatology” This study found that reintroducing certain depleted amino acids into weathered hair using cosmetic treatments can strengthen the hair, improving its look and feel and reducing damage and breakage.
This study found that anti-keratin antibody from immunized cow milk increases the resistance of damaged hair to stretching and inhibits fracture from excessive brushing.
February 2002 in “Dermatologic Surgery” Best hair transplant results happen when tissues are least damaged.

July 2015 in “International Journal of Dermatology” This study observed that multiple familial trichoepitheliomas commonly presented with a cribriform histopathological tumor pattern, differentiating them from solitary trichoepitheliomas.
June 2026 in “Research Square” This study found that lower vitamin D levels were inversely associated with the severity of female pattern hair loss and patchy alopecia areata, but not with telogen effluvium.
May 2026 in “Journal of Basic and Clinical Health Sciences” This study found that certain trichoscopic features, including hair diameter diversity patterns, helped differentiate female androgenetic alopecia from telogen effluvium in women, suggesting their potential use in clinical diagnosis.
July 2024 in “Dermatology Practical & Conceptual” This study found that patients with SARS-CoV-2 associated telogen effluvium experienced hair loss sooner after infection compared to telogen effluvium from other causes, with distinct dermoscopic findings aiding diagnosis.
August 2017 in “Journal of evolution of medical and dental sciences” In this study, researchers evaluated trichoscopy in diagnosing non-scarring alopecia and found diagnostic value in observing diverse hair diameters in androgenetic alopecia, black dots and broken hairs in alopecia areata, and empty follicles in telogen effluvium, supporting trichoscopy's utility in differentiating alopecia types.
