A specific mutation in the K25 gene causes a rare genetic disorder with curly hair at birth and later hair loss, along with dental issues.

Trichocyte filaments have a low-density core and may include proteins for hair structure.

Aging causes changes in hair follicles, leading to weaker hair growth.

Disulfide bonds in keratin fibers break more easily under stress, especially when wet, affecting fiber strength.

Human hair keratins K85 and K35 create unique filament patterns important for early hair formation.

Higher keratin protein levels are important for the wool's shine in Magra sheep.

Hair cuticles remain stable and resilient under stress due to strong protein content and crosslinking.

Beautiful hair is flexible and elastic due to its unique double-layered structure and can be enhanced with succinic acid treatment.

Older thin hair is not just thinner but also has different shape, structure, and stiffness.

Replacing defective mesenchymal cells with normal ones fixes thymic growth issues in 22q11.2DS mouse models.

The genes KRT25 and SP6 affect curly hair in horses, with KRT25 also causing hair loss. If both genes are mutated, the horse gets curly hair and hair loss. KRT25 can hide the effect of SP6.

Researchers developed a new method to clearly see and label hair proteins with minimal errors using advanced freezing and microscopy techniques.

The skin is a complex barrier that protects the body, regulates temperature, and helps with immune responses.

Low-level laser therapy improves hair growth and dermal papilla cell function.

LLPS is crucial for RALF signaling, aiding plant growth and stress resilience.

Curved human hair has different structures on each side, which might cause its shape and is similar to wool.

Curly hair may be caused by a muscle contraction, and muscle relaxants might help treat it.

Cricket nanochitin is denser and stronger than crab nanochitin.

Hair health depends on various factors and hair loss can significantly affect a person's well-being; understanding hair biology is key for creating effective hair care treatments.

Different techniques measure hair properties to ensure cosmetic products work.

CMADK reduces hair damage from bleaching and permanent waving.

Different ethnicities and treatments affect human hair strength and structure.

Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.

Keratin structure in hair is stable at pH 5-6 but disrupts between pH 6-7.

Changes in keratin make hair follicles stiffer.

Antler velvet hair and body hair of red deer have different structures that help with protection and insulation.

Keratin's mechanical properties are influenced by hydrogen bonds and secondary structure, and can be improved with the SPD-2 peptide.

Environmental and cosmetic factors, including heat, chemicals, and sun exposure, can cause hair loss and damage.

Human hair shows promise for non-invasive medical testing, but more research is needed to standardize its use.
