Hidden Hair Damage and the Importance of Multiple Tests

It is of paramount importance for hair researchers to know the history of hair at the time of applying a treatment. The lack of such knowledge can create misleading results. Thus, a stress-strain test in both dry and wet states can provide a rapid means to check the reliability of the information collected, as is shown here.

Replacing Microplastics: Natural Cellulose Offers Gentle and Biodegradable Exfoliation

While cosmetics represent a small source of primary and secondary microplastics in the environment, it is a source that could easily be avoided by using natural biodegradable alternatives. As such, described herein is a research project to identify a natural, biodegradable alternative for peel applications. Plant cellulose was of particular interest.

Zombie Hair and Insights from the Living-dead Connection

"How can we create a synergy between the living and dead part of hair to give consumers the best results? We manipulate the living to improve the dead,” said Thomas Dawson, Jr., Ph.D., during the TRI-Princeton 8th International Conference on Applied Hair Science.

Terminalia Chebula for Preventive and Restorative Anti-aging Benefits*

This paper examines a tannin-enriched Terminalia chebula extract. Discussed are its mechanisms for preventative and restorative anti-aging effects, and skin pigmentation control. A pilot clinical study further confirms the extract’s bioactivity to reduce wrinkles and pigmentation. Improvements in yellowish skin tones also were observed, likely due to glycation reversal.

In evaluating how different solvents may affect the rheology of personal care formulas, it is helpful to consider that different formulation types have distinct relationships between viscosity and elasticity depending on the factors generating their elastic properties.

How Natural Butylene Glycol Advances Market and Rheology Dynamics

Demand for sustainable ingredients in cosmetics and personal care is well-known. Here, a sustainable natural butylene glycol is described to advance this trend and its effects on viscosity and elasticity are assessed in five test formulas.

Keratin Blend Anchors Follicles and Prevents Pollution-induced Hair Fall

Poor scalp health compromises hair quality. As such, the topical application of keratins was explored to increase collagen IV in the scalp skin. Live scalp explants were used to test this approach for improved follicle anchoring and, in turn, protection against environmental assault, hair fall and damage.

Auderset presented a traditional Swiss cow bell to U.S. SCC president Tony O'Lenick as a symbol of the Secretariat's move to New York.

Synesthesia is Music to Our Feel and Taste Receptors

"One of the next (applications) we could see is whether music can improve or boost skin hydration."

To produce a stable emulsion, an emulsifying agent can be added to the oil and water that will either act as a barrier to alter the droplet coalescence rate, or create an interfacial film that can produce repulsive electrical forces between approaching droplets.

Zeta Potential and Particle Size to Predict Emulsion Stability

Emulsions are popular vehicles in skin care due to their affinity for the skin; however, they are thermodynamically unstable systems. This study investigates zeta potential and particle size distribution as potential screening tools to predict instabilities in emulsion-based cosmetic products, to supplement regular accelerated stability testing.
