“…Fourier transform infrared spectroscopy analysis permits the observation of oxidative damage. An increase in the amide I and amide II bands is observed in bleached hair, showing the content of cysteic acid in the hair . The present results showed that the hair treated with formaldehyde and glyoxylic acid did not present oxidative damage since there was no change in the cysteic acid content.…”

Consumers are attracted to the latest fashion trends and different looks. This drives the search for novel hair treatments. Some chemicals present in hair treatment products can penetrate the hair shaft. These materials can either nourish or injure the hair cortex. Different techniques have been used to investigate the mechanism of molecule penetration and the conditions under which penetration occurs. This article reviews the techniques applied for this purpose. Various microscopy techniques are used to capture clear and colourful images to determine the diffusion pathways and the exact location of the molecules under study. However, the laborious sample preparation often leads to sample destruction since cross‐sectioning is often required. While various other techniques have been successfully used for investigating the penetration methods, most of these require different amounts of work to be put in for sample preparation and instrumentation. Several spectroscopic techniques have been used to study the penetration of the molecules because of the high levels of accuracy and the quick response time of these techniques. Moreover, the samples are not damaged during the investigation.

“…The damage on hair after chemical treatment can be assessed using an attenuated total reflectance-Fourier transform infrared spectrophotometer (ATR-FTIR) to detect the presence of characteristic cysteic acid peak at 1040-4 cm −1 [14]. Hair damage assessment is possible because the bonds in hair keratin and their derivatives absorb in the infrared region and produce characteristic vibrational frequencies [14,16,17]. ATR-FTIR is gaining popularity because it is non-destructive to the sample and requires less or no sample preparation [18,19].…”

Background Different hair types respond differently to cosmetic treatments; hence, many options ought to be availed to the consumer. The purpose of this study was to evaluate the use of antioxidant extract from Dicerocaryum senecioides as active alternatives in hair semi‐permanent waving and hair conditioning. Methods The antioxidant phytochemicals were first identified and isolated by thin‐layer chromatography (TLC) and spraying with revealing agents. The antioxidant potency was determined by DPPH antiradical scavenging and ferric reducing power methods. The extract was incorporated in two different formulations to make the extract perm (bio‐semi‐permanent) and the antioxidant hair conditioner (AC). The formulations had their performance examined for hair curling and conditioning on Asian and African hair types. Hair damage was assessed by scanning the surface of treated samples on an attenuated total reflectance–Fourier transform infrared spectrometer (ATR‐FTIR) and by quantifying lost protein on ultraviolet visible (UV‐Vis) spectrophotometer. Results The extract antioxidant had an IC50 of 26.54 ± 0.34 µg/ml exhibiting greater antioxidant potency compared to the controls quercetin (38.84 ± 0.12 µg/ml) and ascorbic acid (35.22 ± 0.07 µg/ml). The extract perm had a lower curling ability indicated by a perm set of 85.10 ± 3.92% and 81.35 ± 2.35% for Asian and African hairs, respectively, while commercial product, ammonium thioglycolate (ATG) had 96.05 ± 1.70% and 93.60 ± 2.21% for the same. The curling of hair with extract perm resulted in less oxidative damage with oxidative peak areas of 3.37 ± 0.09 and 3.71 ± 0.03 as well as lower protein losses of 4.72 ± 0.71 µg/mg and 5.62 ± 0.70 µg/mg on Asian and African hair samples, respectively. The application of AC reduced the oxidative damage peak areas of ATG and extract perm treated Asian hair samples by 1.15 and 0.48 units, respectively. AC was also effective in reducing damage caused by UV radiation on ATG‐treated samples by 1.06 units (African hair) and 1.09 units on Asian hair. Conclusion The results show antioxidant extracts from Dicerocryum senecioides as a promising and safer alternative for hair conditioning and semi‐permanent curling.
