research Effects of Silicone Oil Viscosity on the Physical Structure and Damage Mechanisms of Hair during Permanent Wave Treatment

February 2026 in “Journal of the Korean Society of Cosmetology”

This study found that the viscosity of silicone oil in hair treatments significantly affects wave curling performance and hair damage, with untreated and chemically treated hair showing different optimal viscosities.

research Intermolecular disulfide cross-linked structural change induced by permanent wave treatment of human hair with thioglycolic acid.

1 citations , January 2013 in “PubMed”

In this study, treating hair with thioglycolic acid was found to alter disulfide bond patterns in keratin-associated proteins, shifting them from an ellipsoidal to a near-spherical shape.

research Effect of Aspartic Acid Intermediate Treatment on Virgin Hair by Permanent Wave

1 citations , April 2021 in “Han'gug miyong haghoeji/Journal of the Korean society of cosmetology”

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.

research Effects of Reducing Hair Damage by Permanent Wave Reductants Added Glycerin or Hyaluronic Acid

September 2014 in “Daehan miyong hakoeji”

Adding 2% glycerin or hyaluronic acid to permanent wave treatments reduces hair damage, with hyaluronic acid being more effective.

research Structural change of keratin protein in human hair by permanent waving treatment

70 citations , June 1998 in “Polymer”

This study found that permanent waving treatment partially disrupts the α-helical structure in human hair microfibrils, primarily during the initial reduction phase, rather than just affecting disulphide bonds.

community Rethinking DHT and Hair Loss: Are We Targeting the Wrong Enemy?

in Research/Science 1 year ago

Blocking DHT is not a cure for hair loss; instead, altering how scalp follicles respond to DHT might be more effective. Current treatments like topical finasteride and minoxidil are temporary solutions, and future approaches may involve gene therapy and bioengineering to change follicle behavior.

community Hair loss research is a money grab

227 upvotes 10 months ago

Hair loss is linked to DHT, with treatments like finasteride and minoxidil being common but not definitive. Economic interests influence research, and there is potential for new treatments like PP405 and RU58841.
