coconut oil mineral oil single-fiber hair testing surfactant wash cycles tensile strength torsional stress hair core penetration

Studysummary This study found that coconut oil significantly increased the tensile strength of twisted hair fibers due to its ability to penetrate the hair core, in contrast to mineral oil.

Research cited in this study

8 / 8 results

research Alternative Protocol for Hair Damage Assessment and Comparison of Hair Care Treatments

7 citations , January 2020 in “International Journal of Trichology”

This study observed that regular coconut oil users have significantly reduced hair irregularities compared to non-oil users, as quantified by a new "hair protection factor" metric, highlighting coconut oil's potential in minimizing hair damage.

research Prevention of Lipid Loss from Hair by Surface and Internal Modification

17 citations , July 2019 in “Scientific reports”

This study investigated lipid loss in hair caused by surfactants and found that surface and internal modifications can significantly protect different lipids from depletion, with internal modification preventing 52.0 to 81.3% of lipids in certain groups.

research The Cell Membrane Complex: Three Related but Different Cellular Cohesion Components of Mammalian Hair Fibers

15 citations , May 2010 in “International Journal of Cosmetic Science”

This review discusses new developments in understanding the structure and properties of keratin fiber cell membrane complexes, without reporting new experimental results.

research Torsional Method for Evaluating Hair Damage and Performance of Hair Care Ingredients

9 citations , March 2005 in “International Journal of Cosmetic Science”

This study found that torsional measurements can effectively distinguish the effects of hair care products on the cuticle versus the cortex of hair fibers, unlike tensile measurements.

research Tensile Properties of Twisted Hair Fibers

1 citations , March 2005 in “International Journal of Cosmetic Science”

Twisting hair weakens it, but strength can be recovered at low twist levels.

research Human Hair: A Unique Physicochemical Composite

203 citations , June 2003 in “Journal of the American Academy of Dermatology”

This article reviews the structure and chemistry of hair across ethnicities and how these factors affect hair properties and treatment responses, but reports no new research findings.

Secondary Ion Mass Spectrometric Investigation of Penetration of Coconut and Mineral Oils into Human Hair Fibers: Relevance to Hair Damage

research Secondary Ion Mass Spectrometric Investigation of Penetration of Coconut and Mineral Oils into Human Hair Fibers: Relevance to Hair Damage

11 citations , June 2001 in “PubMed”

Coconut oil can penetrate hair better than mineral oil, potentially protecting against damage.

research Cuticle Damage and the Tensile Properties of Human Hair

27 citations , February 1991

This study found that extensive cuticle damage from diperisophthalic acid oxidation did not alter the tensile properties of human hair, suggesting that these properties are mainly due to the cortex rather than the cuticle.
