In this study, hair bleaching with ammonium persulfate and hydrogen peroxide caused significant damage to hair structure and severe skin reactions in rats, highlighting the need for cautious bleaching procedures.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

This study found that Synsepalum dulcificum seed oil hair treatment significantly reduced hair breakage and improved hair health indices in women, outperforming both placebo and argan oil treatments.

In this study, researchers found that using 0.75% aspartic acid as an intermediate agent for a permanent wave improved wave formation and retention compared to a control in virgin hair, also reducing cuticle damage and maintaining tensile strength.

This article reviews advanced dermabrasion techniques for acne scars and skin lesions, detailing patient selection and procedural steps to enhance therapeutic outcomes and avoid pitfalls, but reports no new findings.

This article reviews the basics of hair follicle biology, laser/tissue interactions, and hirsutism and hypertrichosis causes, discussing the long-pulsed alexandrite laser's role in hair reduction without reporting new clinical results.

This review discusses the presence of undeclared substances, including androgenic steroids, in sports supplements and emphasizes potential health risks, without providing new results; it advises caution and consultation on supplement use.

This study reported that fermented grapeseed oil may enhance hair permeability and improve strength and color retention in chemically treated hair compared to regular grapeseed or silicone oils.

This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

Alpha-hydroxy acids, like glycolic acid, safely improve skin issues and work on all skin types.

This paper reviews hair structure and damage from grooming and cosmetic exposure but reports no new clinical findings; it suggests collaboration between dermatologists and cosmetic chemists to improve hair care products.

This study found that the Epilight multiple wavelength pulsed-intense light source was effective for long-lasting hair removal, particularly in individuals with dark hair and light skin.

This review discusses the impact of various exogenous agents on hair, such as cosmetics and radiation, but reports no new experimental results.

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 case report describes a 23-year-old woman who experienced hair breakage along her anterior hairline due to the formation of bubbles in the hair shafts from blow-drying techniques.

This study compared the effects of direct heat perms and softening heat perms on hair, analyzing damage and morphological changes to understand their impact on hair fibers and provide foundational data for future research.

This article reviews the potential hair-protective effects of Onion and Aloe vera against damage from hair dyes but reports no new experimental results.

This study utilized advanced imaging techniques to quantify hair damage and dye uptake dynamics, revealing that compound penetration in hair is influenced by molecule size and lipophilicity.
