This study found that pretreatment with KP-Cryst fusion proteins effectively protected Asian and Caucasian virgin hair from thermal damage by maintaining higher water content and preventing structural changes during heat application.

This study tested the effects of protective pre-treatments on African hair and found that these treatments, combined with moderate grooming, may help maintain cuticle integrity.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

This review discusses the impact of various external factors like cosmetics, traction, and radiation on hair health and color, but reports no new findings.

This chapter discusses the chemical changes and possible heat-induced hair damage from thermal straightening, as well as controversies surrounding the safety of keratin straightening treatments, but it reports no new clinical results.

This study examined the thermal conductivity of human hair using the Modified Transient Plane Source method, highlighting how frequent thermal, mechanical, and chemical treatments can damage hair by weakening its structure, particularly through changes in keratin that reduce elasticity.

In this study, researchers used the Modified Transient Plane Source method to measure the thermal conductivity of human hair, highlighting that common heat treatments can damage hair structure by altering its protein composition, emphasizing the importance of understanding thermal properties to mitigate such damage.

In this report, a 17-year-old boy received successful scalp reduction surgery for alopecia due to a thermal burn, achieving excellent cosmetic results without hypertrophic or keloidal scarring.

This study developed a biobased copolymer called SELP::KP, showing improved hair strength, elasticity, and conditioning properties while being a safer alternative to conventional chemical treatments, based on application to human hair in a laboratory setting.

This chapter explores the causes and management of hair damage, highlighting effective repair strategies such as protein and lipid replenishment with keratin peptides and citric acid, and identifies social media's role in consumer preferences for protective and conditioning products.

This study reports that a new topical solution, AB-102, containing a high concentration of a weak α1 agonist, significantly reduces hair shedding during brushing by up to 77% without causing cardiac or hemodynamic adverse events.

This study investigated various proteins as eco-friendly hair perming agents for Asian hair and found that bovine serum albumin and keratin achieved perming results comparable to commercial products, while also increasing hair moisture, indicating a protective effect during heat styling.

This study found that modern styling cosmetics can significantly alter hair structure through changes in interfacial chemistry and cohesion, particularly when applied to already damaged hair.

This study found that selected polymeric pretreatments on hair can significantly reduce breakage and protect against thermal damage from hot flat irons by maintaining cuticle integrity and moisture.

Hair damage shows as fragility, dullness, and discoloration, varies by ethnicity, and is worsened by cosmetic procedures and diseases.

This chapter reviews the anatomy and structure of hair, discusses hair damage and analyses, and explores methods for processing hair changes, but presents no new research findings.

In this study, BTP-loaded solid lipid nanoparticles were developed and shown to protect hair from heat-induced damage by enhancing cuticle integrity and thermal resistance in simulated thermal straightening conditions.

This study found that keratin-based particles were able to recover and enhance the mechanical properties and thermal stability of virgin and overbleached Asian hair, improving its strength and smoothness by around 40%, and demonstrated safety in human skin keratinocytes.

This study developed mathematical models showing that heat penetrates individual hair quickly but takes longer to reach the center of hair bundles, helping understand potential damage from high-temperature styling tools.

This study found that thermal hair straightening in Asian women was associated with various signs of scalp and hair damage, including CCCA-like hair loss.

This study found that a sucrose-based crosslinker can effectively straighten hair and maintain durability in high humidity and through repeated washings without affecting the hair's tensile properties or causing surface damage.

Environmental, chemical, mechanical, and personal health factors can all damage hair and contribute to hair loss or changes in hair quality.

Hair straightening methods have advanced to improve effectiveness and reduce damage, but still rely on heat and chemicals.

This review discusses the causes of hair shaft abnormalities and highlights the role of cosmetic products in treating hair disorders, though it reports no new clinical findings.
