“…perming, dyeing, and bleaching) but also by physical or environmental stress in daily life (e.g. brushing, and sunlight-exposure) (1). We confirmed that a combination of both kinds of stress causes severe damage to hair and that oxidative and reductive stress are significant factors regarding hair-damage.…”

Abstract:To confirm the effects of hydrophilic extracts from Rosmarinus officinalis L. (HER) on oxidative and/or reductive hair-damage, we first estimated the HER antioxidant effect by doing a b-carotene decoloring test. We additionally conducted an analysis of the biochemical parameters, for example cysteic acid or chemiluminescence (CL), and observed the morphological changes (snapping and splitting frequency) after chemical and physical hair treatment. Furthermore, we compared the effect of applying HER with the effect of applying no antioxidant or the effect of a typical hydrophilic antioxidant, ascorbic acid (AsA). HER had a strong antioxidant effect in the hydrophilic radical generation system in the b-carotene decoloring test. However, HER exhibited moderate antioxidant effects in the lipophilic radical generation system. Concerning hair-damage, applying HER suppressed cysteic acid in the hair after chemical and physical treatment more than when no antioxidant is applied. In addition, HER and AsA application also suppressed CL intensity in the damaged hair in the system using 2-methyl-6-(4-methoxyphenyl)-3,7-dihydroimidazo[1,2-a]pyrazin-3-one hydrochloride (MCLA). However, HER only exhibited a tendency for CL reduction in damaged hair when we induced CL with short time irradiation of ultraviolet rays (UV) without chemical reagents. Furthermore, HER and AsA suppressed the snapping and splitting frequency in the hair, and the suppression level of HER tended to be stronger than that of AsA. HER demonstrated the antioxidant effect in a hydrophilic radical generation system. Furthermore, HER could prevent oxidation and morphological changes in damaged hair that was subjected to oxidative and/or reductive treatment, such as perming and bleaching, as well as physical treatment, which is postulated to cause hair-damage in daily life.

“…The most common external stress to hair includes not only mechanical/chemical damage, UV exposure, and heat treatment, but also exposure to air pollution. Research on hair care products and ingredients offering protection against air pollution has become a hot topic [1][2][3]. In 2016, Mintel conducted a survey of consumers of hair care products aged from 20 to 49 years, in which 41% of respondents expressed their concern about hair damage by air pollution.…”

“…Its adsorption on hair not only reduces glossiness and moisture, but also causes chemical damage through attached toxic and oxidizing pollutants penetrating inside the hair [5]. Long-term exposure to air pollution can cause damage to both the hair and scalp [1,3,4,6]. There are four methods to protect hair from air pollution: (1) perform deep cleaning to completely remove pollutants from the hair and scalp; (2) reduce air pollution sources, resulting in less solid particulate pollutants becoming adsorbed into hair; (3) provide effective protection for hair to prevent pollutants from entering the hair and causing damage; and (4) neutralize pollutants or the effect by pollutants.…”

Cigarette smoke was used to simulate a polluted environment and an experiment was performed to reveal how virgin and bleached hair are damaged by a polluted environment. The dry/wet combability, surface contact angle, tryptophan content, and cuticle morphology of the smoke exposed hair were evaluated, and compared to unexposed virgin hair. The results showed that pollution exposure can cause significant chemical damage to hair. In particular, virgin hair exposure to pollution can cause damage to the hair cuticles (higher wet/dry combing), protein degradation, and a more hydrophilic hair surface. The experiment also demonstrated that the styling polymer, polyimide-1 (isobutylene/dimethyl amino propyl maleimide/ethoxylated maleimide/maleic acid copolymer), can provide effective protection against such hair damage.
