L-cysteine slows down the breaking of bonds in hair due to electrostatic interactions.

The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.

The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.

The study found that thioglycolic acid breaks down hair bonds more consistently than l-cysteine, which is less damaging to hair.

Hair color affects light reflection, with black hair having higher cuticle angles and lighter hair showing less specular reflection.

The effectiveness of reducing agents on hair fibers depends on their electrode potentials.

Human hair has different protein structures in its cuticle and cortex.

Hair shine can be measured by how it reflects laser light.

Fiber implantation for pattern baldness was largely unsuccessful with many complications and is not recommended.

Researchers developed a new model for more realistic computer graphics rendering of hair by considering how light scatters on hair fibers.

Researchers developed a new model for more realistic computer graphics of hair by considering how light scatters on hair fibers.

Chemical hair straightening changes hair proteins and mostly fixes broken bonds.

Chemical treatments change hair surface properties, making it more hydrophilic and able to bind conditioners.

Researchers developed a new method to identify animal hair in textiles, which is effective for various fibers and more reliable than previous methods.

Cashmere fiber diameter in Tibetan goats is influenced by their stress, oxygen, and metabolic adaptations.

Thioglycerol treatment at pH 9.0 with ammonia causes less hair damage and better waving than thioglycolic acid.

Merino sheep have fewer wool follicles at birth than before birth.

The 14-3-3σ gene is essential for preventing hair loss.

Isotretinoin can rarely cause hair to grow curly.

Small amounts of DNA can be found in the hair shaft, especially near the root, but it decreases with hair treatments and washing.

Permed hair degrades faster and shows more damage after protease treatment compared to untreated hair.

The marine protein complex, Viviscal®, was found to effectively reduce hair loss and improve hair, skin, and nails quality in women.

Synthetic hair fibers for hair restoration were controversial in 2009 due to health risks and lack of support from the International Society of Hair Restoration.

Flightless I protein affects hair growth, with low levels delaying it and high levels increasing hair length in rodents.

The document suggests that nerve issues might contribute to hair loss and that testing sensation could predict these nerve problems.

Fusion proteins can protect hair from heat damage.

Hair implants can cause infections, allergic reactions, itching, and scarring.

Artificial hair implantation is generally safe and can restore hair when other treatments fail, but some patients may experience side effects.

Artificial hair implants can still cause side effects despite improvements.

Lichen planopilaris is a rare, chronic condition causing hair loss, mainly in middle-aged women, and early treatment is important to prevent permanent baldness.
