This review examines regenerative hair waves and complex hair cycle domains in transgenic mice, highlighting how these dynamic processes contribute to skin regeneration and the physiological regulation of organs, but reports no new experimental results.

This study found that intra-follicular Wnt signaling and dermal BMP signaling oscillate differently during hair cycling in mice, affecting hair wave propagation and phases of hair growth.

This study found that adding rose hip extract to permanent wave solutions increased wave effectiveness and reduced hair damage, although variations in hair type may affect the results.

This study found that the viscosity of silicone oil in hair treatments significantly affects wave curling performance and hair damage, with untreated and chemically treated hair showing different optimal viscosities.

This study found that permanent wave lotion I extracts proteins from human hair, with molecular weights ranging from 5,000 to 65,000, which may elucidate hair damage mechanisms.

Multiple-wavelength radiation helps hair grow by boosting early hair follicle development.

This study suggests that LED light may promote the proliferation of human dermal papilla cells through the activation of specific signaling pathways.

This study developed a double-wavelength laser scanning microphotometer to measure hair shaft and follicle absorbance, improving spatial resolution and reducing light scattering effects in vitro.

This review highlights the advantages of a new "Multi-Wave Punch" for follicular unit extraction in hair transplantation, noting its design reduces follicular damage and improves graft quality by effectively separating hair follicles from surrounding tissue.

In this study, a triple wavelength laser was found to be highly effective and well-tolerated for reducing hair in Indian women with Fitzpatrick skin types III and IV, achieving an average hair count reduction of 86.5%, with only mild and transient adverse effects observed.

This study found that using dual-wavelength low-level laser therapy is more effective for hair regrowth in mice than single-wavelength treatment and significantly better than no treatment, based on 14 days of phototherapy with LED lights.

Adding 2% glycerin or hyaluronic acid to permanent wave treatments reduces hair damage, with hyaluronic acid being more effective.

This study found that aging mice experience slower and more fragmented hair cycle waves, but transplanting aged skin to a young host can partially restore hair cycling, implicating extracellular factors.

The study discusses using red light therapy for hair regrowth, noting red light alone may aid non-inflammatory hair loss, while infrared-red light combination is necessary for conditions like alopecia areata.

This study found that low-level laser therapy with an 830-nm wavelength most significantly stimulated hair growth in rats, compared to other wavelengths tested.

This study found that permanent waving treatment induces structural changes in the cortex proteins of white human hair, significantly reducing its tensile strength without altering the S-S band intensity.

In this study, extracorporeal shock wave treatment for female pattern hair loss resulted in significant increases in hair count and thickness in 20 women, with 85% of participants perceiving improvements in hair volume.

This study found that tamoxifen citrate markedly inhibited castration-induced diffuse hair growth in castrated female mice, while cyproterone showed only slight inhibition in male mice.

This study found that melatonin implants caused male weasels to molt, develop a new white winter coat, and become reproductively inactive, suggesting melatonin affects their neuroendocrine system.

In this study, researchers found that using 0.75% aspartic acid as an intermediate agent for a permanent wave improved wave formation and retention compared to a control in virgin hair, also reducing cuticle damage and maintaining tensile strength.

The researchers reported that lavender shampoo activated alpha brain waves, suggesting calming and memory effects, while geranium shampoo enhanced arousal and memory by stimulating brain waves in the laryngeal lobe.

Among individuals with skin types II and III, this study found the 755 nm laser more effective for axillary hair removal than the dual-wavelength laser, with a better safety profile and enduring results up to 12 months.

This study observed that dandruff-affected scalp skin has increased T-cell infiltration in the epidermis and a reduction in the hair follicle's physiological immune privilege, particularly in the suprabulbar outer root sheath area, indicating a distinct immune microenvironment compared to healthy scalp.

This study reported that using photoacoustic waves to enhance transdermal delivery of encapsulated minoxidil can significantly increase hair growth while reducing treatment frequency and systemic side effects.

In this study, treating hair with thioglycolic acid was found to alter disulfide bond patterns in keratin-associated proteins, shifting them from an ellipsoidal to a near-spherical shape.

This systematic review found that photobiomodulation therapies using ultraviolet and infrared light effectively treated alopecia areata, while red and infrared light treatments were effective for androgenetic alopecia.

This study found that microfibrils play a crucial role in shaping permanent waves by thioglycolic acid, and treating damaged hair with hydrolyzed keratin improved both waving efficiency and hair damage.
