Heated styling appliances, such as straightening irons, have grown in popularity in recent years, as have hair products such as heat-protection sprays. In this study we investigate whether the water in a heat-protection spray can affect the level of damage caused by heat styling. Tryptophan damage from heat styling was measured using fluorescence spectroscopy, and structural damage was investigated using light microscopy and single-fiber tensile testing. Hair samples were heat treated with… Expand
Measurement of hair thermal diffusivity with infrared microscopy enhanced Ångström's method
Abstract While heat acts as an essential component of various hair care processes, the thermal properties of hair are little studied and these properties dictate how heat is spread and stored inExpand
Measurement of Hair Thermal Diffusivity with Infrared Microscopy Enhanced Ångström's Method
While heat acts as an essential component of various hair care processes, the thermal properties of hair are little studied and these properties dictate how heat is spread and stored in hair. Here,Expand
Crystallin Fusion Proteins Improve the Thermal Properties of Hair
The results proved the capacity of the fusion proteins to bind to hair and protect it against high temperatures', supporting the development of new formulations based on the KP-Cryst proteins. Expand
Linear and nonlinear relations between DSC parameters and elastic moduli for chemically and thermally treated human hair
Against the practical context of thermal straightening, hair samples were obtained with a chemical (bleaching) as well as a cumulative thermal history (0–800 s, 200 °C). On these samples, tensileExpand
Kinetics of the changes imparted to the main structural components of human hair by thermal treatment
Abstract Thermal straightening of hair is a wide-spread consumer practice, which will impart specific hair damage. For practically relevant, cumulative conditions of thermal treatment (straighteningExpand
Quantifying hair shape and hair damage induced during reshaping of hair.
Spectroscopic imaging techniques and fluorescence spectrophotometry are introduced as tools to assess the biochemical state of the hair fiber as a result of hair shape modification regimens. Expand
Integrating Design Methodology, Thermal Sciences, and Customer Needs to Address Challenges in the Hair Care Industry
Although the hair care industry is a multi-billion dollar industry, there still remains a dearth in the available technologies and research methods to answer one simple question: What temperature andExpand
Hair weathering, Part 1: Hair structure and pathogenesis
H air weathering is the manifestation of hair shaft defects due to cosmetic or environmental factors including physical or chemical trauma from hairstyling procedures and external factors such as UV radiation, wind, humidity, sea salt, chlorinated water, dust, pollution, and friction. Expand
Clinical Signs of Hair Damage
The environment causes daily damage to the hair shaft that cannot be repaired and is more evident in the distal part of long hair. Clinical signs of hair damage depend on type of damage and severityExpand
Using Do-It-Yourself Practitioners as Lead Users: A Case Study on the Hair Care Industry
Lead users play an integral part in helping engineers to identify latent needs of customers, and this approach has been used in a variety of ways within the design community. However, despite theirExpand


Effects of thermal treatments with a curling iron on hair fiber.
Fibers subjected to repeated curling in the dry condition show slight increases in tensile mechanical properties, characteristic of a crosslinked fiber, and conditioners treated with conditioners show an improvement in characteristic life. Expand
Thermal degradation of hair. II. Effect of selected polymers and surfactants
Fluorescence spectroscopy, combing analysis, and texture analysis with a dual-cantilever bending accessory have been employed to study the effect of pretreatments on the thermal damage of hair. TheExpand
The cracking of human hair cuticles by cyclical thermal stresses
Cycles of wetting and blow-drying were applied to hair fibers and resulted in the formation of multiple cracks on the hair cuticles. The peculiarity of these cracks was that they always appearedExpand

acquired trichorrhexis nodosa is the most common hair shaft anomaly in which the hair is fragile and easily broken; on microscopic examination, filaments of the hair shaft can be seen splayed apart (Fig 1). Expand
Chemical and Physical Behavior of Human Hair
At or near its surface, hair fibers contain a thick protective cover consisting of six to eight layers of flat overlapping scale-like structures called cuticle or scales which consists of high sulfurExpand
