In the mechanical testing world, the tendency for materials to fail under a repeated stimulus is termed fatigue testing, and this article discusses this topic in relation to hair breakage. It will be shown that this alternative testing approach provides considerable insight into the cause of hair breakage, and subsequently allows for the identification of strategies for its minimization; it will also be demonstrated how learning this provides the underlying theory by which anti-breakage and even “strengthening” claims are crafted.

The essential elements of a natural hair styling liquid or gel are: a film-forming substance to keep hair in place, and a base to deliver it. This base may be as simple as thickened water or as complex as a gel or cream.

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.

Nanoporous organosilica particles were developed to swell upon the addition of organic solvents. These are evaluated here for encapsulating and controlling the release of fragrance. Slower, continuous release was observed, suggesting their ability to extend sensory benefits. In addition, the stimulated release of encapsulated lidocaine was studied, and results implicate their use to deliver cosmetic actives.

It is well-known that perfumes can affect the viscosity of bubble bath or shampoo formulations. Usually they have a thinning effect, but they can also cause a viscosity increase. The effect and its magnitude will vary with perfume type and also with the product formulation. Small changes in the latter can cause large changes in a perfume's effect on the viscosity.

Many certified organic shampoos and body washes use soaps such as potassium cocoate as their primary cleansing agent, partially due to a lack of suitable, organically approved foaming alternatives. This article reviews the use of modern surfactants and emulsifiers developed based on a green and eco-conscious philosophy.

This article reviews and assesses damage types caused to hair before and after artificial coloration, i.e., by bleaching, perming, heat treatment, UV exposure and shampooing, to compare how they impact color durability individually and combined. Formulation emerges as the key to designing shampoos that efficiently deliver actives to improve color protection against these and other damage types.
