November 2023 in “Cosmetics” 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.
December 2025 in “The American Journal of Medical Sciences and Pharmaceutical Research” This study outlines how combined ultrasonic and infrared hair treatments may enhance hair restoration and performance by breaking down keratin disulfide bonds for better treatment access and sealing cuticle scales to preserve improvements, with potential applications in salon and home settings.

July 1964 in “PubMed” This study observed that undifferentiated matrix cells at the base of the hair follicle differentiate into the medulla, cortex, cuticle, and inner root sheath cell types through specific morphological changes.
May 2026 in “International Journal of Cosmetic Science” In this study, researchers observed that using an Avena strigosa seed extract on chemically damaged hair significantly improved hair properties, including strength, gloss, and surface quality, by reinforcing keratin bonding and sealing cuticle damage.
March 2026 in “ACS Applied Bio Materials” In this study, a copolymer made from Tung oil and Tung free fatty acids demonstrated improved mechanical and thermal properties for hair repair, with enhanced resistance and flexibility observed in treated bleached hair, suggesting its potential as a sustainable biopolymer for cosmetic applications.
