Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.

This study found that the circular RNA circCOL1A1 influences the formation of superior-quality brush hair in white goats by regulating hair follicle stem cell behavior and interacting with the miR-149-5p/CMTM3/AR axis.

This paper compiles previously observed similarities in biomagnetic fields emitted by human hair and mouse vibrissa follicles, with findings supporting distinctive patterns of biomagnetic activity skewed to one side.

In this study, researchers found that washing hair 5–6 times per week results in higher satisfaction and better objective and subjective hair and scalp conditions among Asian populations, with no observed detrimental effects from frequent washing.

This article reviews the condition plica neuropathica, including its manifestations, potential causes, and treatment, but it does not provide new clinical findings.

This pilot study found that examining changes in scalp scales after scraping may effectively distinguish seborrheic dermatitis associated with androgenetic alopecia from fibrosing alopecia in a pattern distribution.

This review discusses various types of hair dyes, their mechanisms of action, molecular structures, application methods, and formulation aspects, but reports no new research findings.

This study found that a ceramide derived from sphinganine can bind to African–American hair, reducing breakage when applied in a shampoo after relaxing treatments.

This paper presents a culturally informed protocol designed to improve the collection of hair samples from African Americans for cortisol measurement, illustrating its application with community-based study data.

This review utilizes clinical vignettes to detail various pain syndromes associated with multiple sclerosis, including their pathophysiology and management strategies, highlighting conditions like central neuropathic pain, Lhermitte's phenomenon, and trigeminal neuralgia as they relate to different lesion types.

This study identified key cells and pathways needed for the development of touch receptor patterns in mouse skin, notably that certain keratinocytes are crucial for innervation patterns, while Merkel cells and BMP signaling have distinct roles.

This study found that Wnt signaling, crucial for lung development, may be disrupted in severe asthma, potentially affecting cell proliferation and senescence through complex mechanisms.

This study found that bleaching, dyeing, and UVA/Vis radiation caused significant cuticle damage and protein loss in both Caucasian and Afro-ethnic hair, highlighting the aggressive nature of these treatments.

This review discusses the effects of chemical hair straighteners and reports associated side effects like scalp inflammation and hair damage, noting the variability of findings and the need for further research.

This study found that washing hair with surfactants reduces the internal density of hair due to cuticle lifting, and suggests that a cuticle-sealing strategy can inhibit this effect and maintain hair homeostasis.

This study found that alcoholic extracts of Blumea eriantha DC exhibited significant hair growth activity, primarily attributed to the phytoconstituent Dimethyl sulfone.

This study presents two case reports where patients experienced hair loss during treatment with the SSRI sertraline, highlighting this rare but potential side effect.

Lye relaxers don't significantly change hair cortisol levels.

This study evaluated a hair mask containing rice germ oil GX-N and ferulic acid on damaged hair and found that rice germ oil GX-N improved hair characteristics after bleaching, UV, and heat exposure, but adding ferulic acid did not provide extra benefits.

This case report observed that multiple sclerosis treatments were associated with worsening alopecia in a woman, highlighting the importance of informing patients about this potential side effect.

In this study, researchers developed cationic liposomes encapsulated with keratin to improve the recovery of UV-damaged hair, finding that these liposomes significantly improved keratin penetration and reduced protein denaturation and lipid peroxidation, resulting in smoother hair surfaces compared to keratin solution alone.

This article discusses hair loss disorders, underscoring the recent therapeutic advance of ritlecitinib, approved for severe alopecia areata in individuals aged 12 and older, and the ongoing need to manage expectations given limited treatment options.

This article highlights that trichorrhexis nodosa, a common type of hair breakage, is influenced by factors like heat styling and chemical treatments, with potential FDA action on formaldehyde usage in hair products potentially altering its treatment approach.

This study found that the topical application of DA-OTC-002, a combination of synephrine and tyramine hydrochloride, significantly reduced immediate hair shedding in women by 62.5% compared to a placebo, without any observed adverse effects.

In this study, researchers analyzed internet and social media content related to hair loss, finding widespread misinformation about its causes and treatments, including unfounded criticisms of conventional therapies and promotion of alternative remedies.

This study reports that acute telogen effluvium, characterized by sudden hair loss occurring 2 to 3 months after a physical stressor, is not widely caused by daily life stress, with spontaneous regrowth usually happening within 3 to 6 months unless the trigger recurs.

Platelet-rich fibrin is becoming popular for medical and cosmetic uses like hair growth and natural fillers.
