When formulating a hair care product, there is often a need for testing that validates the product’s technical performance. This testing provides guidance to create formulas with appropriate performance, while also communicating the product’s message to the consumer. This article discusses the use of instrumental combing measurements when formulating hair conditioning products.

The quest for PEG-free surfactants and emulsifiers has led to new classes of vegetal-derived, ethylene oxidefree ingredients for environmentally friendly personal care products. Two such ingredients, described here, are based on the combination of olive oil and vegetable proteins with the first derived from oat and the second, with glutamic acid. These materials provide mildness and skin protection benefits.

In this article, several ingredients are reviewed for development of sustainable shampoo formulations. Some of the functional ingredients reviewed are plant-based alternatives to existing, petro sourced ingredients while others are mild, sulfate-free and/ or ethoxylate-free alternatives to existing surfactant systems, thickening solutions for challenging media based on naturally derived polymers and efficacy boosters that reduce the use of non-renewable actives with equal benefit for the consumer.

The use of sulfonated alkyl polyglucosides (SAPG) to replace lauryl sulfates and lauryl ether sulfates in sulfate-free formulations has previously been discussed. These primary surfactants were created with environmental and human safety in mind. The current paper describes more recent work with this material, specifically focusing on the lauryl version of SAPG.

Signal transductions mediated by integrins are shown to be involved in hair growth and development. Here, the authors investigate the effect of a botanical corn extract on the expression of different integrins via in vitro measurements of hair shaft elongation. Scalp biopsies show the daily application of the active may improve hair elongation.
