Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.

Washing permed hair after using thioglycolic acid helps reform strong bonds, making hair stronger.

Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.

Disulfide bonds make keratin in hair stronger and tougher.

Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.

Permanent wave treatment with thioglycolic acid changes hair structure by altering disulfide bonds.

TGase 3 helps build hair structure by forming strong bonds between proteins.

Using both TGA and DTDG in hair straightening reduces hair damage compared to using TGA alone.

Changes in keratin make hair follicles stiffer.

Hair's strength and flexibility come from its protein structure and molecular interactions.

Different ethnicities and treatments affect human hair strength and structure.

Thioglycolate lotions are the most popular method for permanent waving and hair straightening.

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

The article explains the genetic causes and symptoms of various hair disorders and highlights the need for more research to find treatments.

Chemical treatments and daily stresses damage hair, especially the cuticle layer.

Lipase H is important for hair follicle function and shaping hair fibers.

VEGF helps squamous cell carcinoma grow in ways beyond just blood vessel formation.

Hair and nail conditions can stabilize or improve over time, and new treatments show promise.

The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

Scientists successfully created mouse hair proteins in the lab, which are stable and similar to natural hair.

A new method accurately measures amino acids in treated hair, showing bleaching reduces amino acids while protein treatments increase them.

Small proline-rich proteins and trichohyalin help make epithelial tissues tougher and more flexible.

Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.

Keratin peptides can change hair shape gently without harsh chemicals.

TGM3 is important for skin and hair structure and may help diagnose cancer.

Brazilian keratin treatments can straighten hair but may contain harmful formaldehyde.

Modified keratin binds better to hair, especially bleached hair.
