Protein hair straighteners damage the hair more than hair dyes.

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

Low fluence photoepilation temporarily removes hair by targeting the hair follicle's pigmented area without severe damage.

Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.

The document concludes that both internal stem cell factors and external influences like the environment and hormones affect hair loss and aging, with potential treatments focusing on these areas.

Different hair protein amounts change the strength of keratin/chitosan gels, useful for making predictable tissue engineering materials.

Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.

Black women's unique hair characteristics and styling practices can lead to specific scalp conditions, which require early diagnosis and appropriate treatment.

Loss of Fz6 disrupts hair follicle and associated structures' orientation.

Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.

The herbal cream was found to be a safe and effective alternative for hair growth, similar to minoxidil.

2-iminothiorane hydrochloride improves hair waving permanence without damage.

Shampoo B, which uses water-soluble silicone, is better at detangling hair in wet conditions due to its two-layer conditioning film.

Heat transfer in hair is slower in groups of hair, increasing the risk of damage from high-temperature styling tools.

Hair stiffness is higher when it has more para-like cortical cells.

Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.

Lipids are important for healthy hair, but their exact role is not fully understood and needs more research.

Cosmetic procedures can harm hair, but damage can be minimized with knowledge and care; however, once hair is damaged, it cannot be reliably repaired.

The Rotterdam Study updated findings on elderly health, focusing on heart disease, genetics, lifestyle effects, and disease understanding.

The Rotterdam Study found risk factors for elderly diseases, links between lifestyle and genetics with health conditions, and aimed to explore new areas like DNA methylation and sensory input effects on brain function.

The Rotterdam Study aims to understand disease causes in the elderly and has found new risk factors and genetic influences on various conditions.

Stem cell niches support, regulate, and coordinate stem cell functions.

Microneedles improve drug delivery in various body parts, are safe and painless, and show promise in cosmetology, vaccination, insulin delivery, and other medical applications.

CCCA is a hair loss type affecting African women, possibly caused by grooming and chemicals, with various treatments and needing more research.

Electrospun nanofibers show promise for enhancing blood vessel growth in tissue engineering but need further research to improve their effectiveness.

Most low-level light therapy studies did not accurately report how light was measured, affecting treatment reliability.

Multiphoton microscopy is a promising tool for detailed skin imaging and could improve patient care if its challenges are addressed.

Advancements in creating skin grafts with biomaterials and stem cells are promising, but more research is needed for clinical application.

The conclusion is that we need more effective hair loss treatments than the current ones, and these could include new drugs, gene and stem cell therapy, hormones, and scalp cooling, but they all need thorough safety testing.

Skin aging is largely due to differences in stiffness and elasticity between skin layers, leading to wrinkles.
