research Raman spectroscopic analysis of L‐phenylalanine and hydrolyzed eggwhite protein penetration into keratin fibers

12 citations , June 2011 in “Journal of applied polymer science”

This study found that hydrophobic amino acids from egg white hydrolyzed protein and L-phenylalanine effectively penetrate deep into the human hair fiber, increasing specific contents in both virgin and bleached hair.

research Analysis of structural changes in permanent waved human hair using Raman spectroscopy

45 citations , December 2006 in “Biopolymers”

This study found that permanent waving treatment induces structural changes in the cortex proteins of white human hair, significantly reducing its tensile strength without altering the S-S band intensity.

research Analysis of structural change in keratin fibers resulting from chemical treatments using Raman spectroscopy

52 citations , February 2005 in “Biopolymers”

In this study, chemical treatments during permanent hair straightening were found to randomize proteins in the cortex, aiding in the reconnection of disulfide bonds during oxidation.

research Analysis of heterogeneous reaction between reducing agents and keratin fibers using Raman spectroscopy and microspectrophotometry

20 citations , December 2012 in “Journal of molecular structure”

This study found that at pH 9.0, CYS penetrated less and caused less damage to virgin human hair than TG because it barely reached the cortex region.

research Conformational differences in protein disulfide linkages between normal hair and hair from subjects with trichothiodystrophy: A quantitative analysis by Raman microspectroscopy

53 citations , March 2006 in “Biopolymers”

This study suggests that increased amounts of less stable disulfide conformers in hair shafts may be linked to the brittleness observed in trichothiodystrophy.

community Attempting PP-405 topical gel reformulation

20 upvotes 2 weeks ago

A user is attempting to reformulate a topical gel using PP-405 for hair loss, aiming to enhance its effectiveness with additional compounds. They discuss the potential of PP-405 compared to other treatments like Minoxidil and GT20029, and emphasize the importance of proper formulation for efficacy.

community Losing my youthful look: Enjoying it while it lasts

38 upvotes 11 months ago

The conversation discusses hair loss treatments, focusing on the use of finasteride (fin) and minoxidil (min), with some users recommending dutasteride (dut) for stronger results. Many users emphasize that these treatments are affordable and effective, with some sharing personal experiences of hair regrowth and side effects.

community Joined the Dutasteride Master Race

586 upvotes 1 year ago

Dutasteride and finasteride are discussed for hair loss treatment, with users sharing experiences and debating their effectiveness and side effects. Celebrities are noted as common users, and there is debate over which treatment is superior.

community Pyrilutamide just launched internationally, and all you're doing is hating

in Product 2 years ago

The post and conversation are about the high cost and skepticism surrounding pyrilutamide as a hair loss treatment, with comparisons to minoxidil, finasteride, and RU58841. The original poster defends pyrilutamide's effectiveness and criticizes others for dismissing it without proper understanding.

community 0.5mg Dutasteride promotes more “regrowth” than 5mg oral Minoxidil

in Research/Science 117 upvotes 2 years ago

Dutasteride promotes more hair regrowth than Minoxidil. Users discuss combining treatments for better results and share personal experiences with side effects.
