Why do we have curls? Let’s start by saying right away that this question from the world of hair isn’t so easy to answer either. We look into the hairy matter with our colleague Dr. Hans-Martin Haake, Head of Application Technology Personal Care at BASF.

Our hair doesn’t just make us feel and look good, it’s also like a hard drive that doesn’t forget anything. Forensic toxicology makes especially good use of these properties.

Healthy hair, oily hair, hair that is too thin or coarse: descriptions everyone has likely heard before. But porous hair? What does that mean?

Water plays a key role in cosmetic products and how they are manufactured. But what happens if water is downgraded to a supporting role and its proportion of the end product is reduced or eliminated entirely? Liquid cosmetic products become solid products, known as bars. This trend is not new, though.

Many trends in the cosmetics industry are helped along by companies and manufacturers carrying out intensive research, then constantly improving their products. The "clean beauty" movement also benefits from this approach. When it comes to the "no shampoo" trend, though, it doesn't work. The whole idea is to do without shampoo altogether.
