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…

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 in

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.

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, tensile

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.

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 and

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.

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 severity
