research Crystallin Fusion Proteins Improve the Thermal Properties of Hair
Fusion proteins can protect hair from heat damage.
research The Failure Behavior of the Anchorage of Hairs During Slow Extraction
Growing hairs are easier to pull out than resting hairs due to different anchorage strengths.
research Topological Distribution of Wound Stiffness Modulates Wound-Induced Hair Follicle Neogenesis
The stiffness of a wound affects hair growth during healing, with less stiff areas growing more hair.
research A New Approach to the Bending Properties of Hair Fibers
The new test shows how hair treatments affect hair's bending stiffness by swinging a pendulum through hair fibers.
research Age-Associated Thin Hair Displays Molecular, Structural, and Mechanical Characteristic Changes
Older thin hair is not just thinner but also has different shape, structure, and stiffness.
research Modeling Dynamic Hair as a Continuum
The authors created a realistic and efficient method to simulate hair movement by combining fluid dynamics with individual hair strand behavior.
research The Secrets of Beautiful Hair: Why Is It Flexible and Elastic?
Beautiful hair is flexible and elastic due to its unique double-layered structure and can be enhanced with succinic acid treatment.
research The SYP123-VAMP727 SNARE Complex Is Involved in the Delivery of Inner Cell Wall Components to the Root Hair Shank in Arabidopsis
