As the smallest alpha hydroxy acid (AHA), glycolic acid is frequently found in anti-aging products due to its ability to penetrate skin and reduce wrinkles, acne scarring, hyperpigmentation and other conditions. This work describes how it is also able to penetrate into hair and, in doing so, bring about a number of changes to the internal fiber properties.

The most common approach to determine ingredient deposition on hair is to analyze the treated tresses, but this poses several challenges. Instead, the authors describe a novel approach based on determining the amount of ingredient collected in the rinse water, and back-calculating the amount deposited on hair. Development and validation efforts discussed here use polydimethylsiloxane as a model compound.

This work evaluates the impact of applied pressure during sample spreading on the in vitro measurement of UV transmission. The authors work in a range of pressures between 50–200 g and demonstrate that pressure control is a key parameter that should be strictly controlled to ensure the reliability of test results.
