Your Hair on Acid: The Influence of Carboxylic Acids
In recent years, the effects of carboxylic acids on hair are becoming better recognized and products touting their benefits are finding their way onto shelves.

Glyoxylic acid treatments are now being pushed as an alternative to Brazilian Keratin products, while a disruptive product claiming to induce new cross-links in the hair is based on maleic acid. This article, published in Cosmetics & Toiletries, explores the efficacy of these materials and presents possible explanations for their effectiveness.
