Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.

This study suggests that corkscrew hairs in tinea capitis result from internal hair damage by Trichophyton violaceum and external resistance from scalp scales.

This study demonstrated that stem cells from the small intestine can differentiate into skin cells and reduce skin damage in irradiated mice, supporting the theory of stem cell plasticity.

This study found that red ginseng oil promoted hair growth and protected against UVC-induced skin damage in mouse models.

This study found that stem cell transplantation effectively reduced acute inflammation-induced testicular damage, suggesting potential for cell-based therapies in addressing male infertility.

This study observed that including cationic minoxidil particles in a shampoo facilitated notable hair growth promotion despite a negative surface charge after rinsing, likely due to ionic interactions with the skin.

In this rat study, bone marrow mesenchymal stem cell therapy reduced mortality and intestinal damage in acute liver failure by alleviating endotoxemia.

In this study, researchers found that specific enzyme activities in young females' hair follicles were correlated with changes in hair shaft structure and properties, and permanent waving was associated with chemical changes that suggest hair damage.

This review discusses manipulating the stem cell niche as a strategy in regenerative medicine to repair damaged tissues, highlighting the potential benefits and challenges but reporting no new results.

This study found that using a Picosecond IR Laser (PIRL) on mouse skin led to less tissue damage and scarring compared to conventional surgical lasers and tools.

This article discusses the role of neurohormones and neuropeptides in hair follicle pigmentation and outlines promising neuroendocrinological strategies to address greying and damage, but reports no new clinical results.

In this study, researchers found that L-cysteine interacted electrostatically with anionic ions on the surface of keratin fibers in human hair, reducing the rate of disulfide bond disconnection at pH 9.0.

In this study, researchers found that hair follicle-derived mesenchymal stem cells, modified to overexpress extracellular matrix protein 1, significantly improved liver function and reduced liver damage in cirrhotic mice by inhibiting hepatic stellate cell activation and TGF-β/Smad signaling.

This study found that chemically modifying hair with 2-iminothiorane hydrochloride improved the permanence of hair setting without damaging the hair by increasing disulfide bonds.

This study found that dual-frequency ultrasound with microbubble cavitation significantly enhanced minoxidil delivery and hair growth in both lab and animal models compared to single-frequency ultrasound, without damaging the skin in mice.

This study observed that hairless HRS/J mice were resistant to Bacillus anthracis infection at the skin's surface, suggesting resistance may be due to increased dermal neutrophils rather than non-functional hair follicles.

This study found that intense pulsed light treatment primarily targets pigmented structures in hair follicles and may damage dermal papilla cells at high energy levels, but stem cells are mostly spared.

FUE can be successfully done on African-American hair by using larger punch tools and careful techniques to reduce hair damage.

In this study, tresses treated with pH 1.0 acid straightener showed better straightening but more damage to hair properties compared to those treated with pH 2.0.

In this study, while young rats fed a commercial standard diet with possibly deteriorated oil showed normal growth, they also exhibited liver surface changes and altered serum lipid levels compared to those on a defined diet.

This review summarizes the link between acne pathogenesis and skin barrier dysfunction, noting that more severe acne correlates with greater skin barrier damage, but reports no new clinical results.

This case study details an elderly patient with multiple nasal vestibular furunculosis leading to severe tissue damage and a nasolabial fistula, which was addressed using an alar advancement flap after allowing for tissue healing.

In this study, researchers found that chemical treatments like bleaching can cause severe damage to the hair cuticle, with previously modified hair showing complete deterioration compared to the partial degradation seen in virgin hair, highlighting the need for mindful cosmetic practices.

This review suggests that combining nanotechnology with herbal components in hair cosmetics may improve the delivery and effectiveness of treatments for issues like damage, dandruff, and hair loss.

This study found that disrupted cholesterol homeostasis impairs hair regrowth in individuals with primary cicatricial alopecia by damaging hair follicle stem cells, highlighting the importance of cholesterol in maintaining stem cell function and hair follicle integrity.

This study describes the development of an herbal hair oil using thirteen ingredients to address various hair problems like baldness, dandruff, and hair damage, although the abstract does not report results or evaluate efficacy.

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.

This review discusses the potential of evaluating hair follicle characteristics as early indicators of vascular impairment and organ damage in pre-diabetic individuals, but reports no new clinical results.

This study suggests that low level laser therapy may promote hair cell regeneration in rat cochlear explants following gentamicin-induced damage.

In this study, treatments using a shampoo and conditioner with hematin helped repair damaged hair by depositing a cuticle-like structure, straightening hair as observed through electron microscopy.
