research Characterization of the Promoter Regions of Two Sheep Keratin-Associated Protein Genes for Hair Cortex-Specific Expression

14 citations , April 2016 in “PloS one”

This study found that the promoter region of the sheep KRTAP11-1 gene drives specific transcriptional activity in wool follicles, suggesting it may regulate hair keratinocyte specificity.

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 New method of dyeing keratin fibers using poly(ethylene imine) and its coloring mechanism

6 citations , October 2003 in “Journal of applied polymer science”

This study found that using poly(ethylene imine) as a counterion reagent improved the colorability and shampoo fastness of bleached human hair when dyed with an acid dye.

research Mapping the accessibility of the disulfide crosslink network in the wool fiber cortex

22 citations , November 2014 in “Proteins Structure Function and Bioinformatics”

In this study, researchers mapped cysteine accessibility in wool keratins and KAPs, revealing that certain cysteines in keratin end domains and Types I and II rod domains are accessible and likely involved in forming disulfide bonds.

community Dec 2024 vs now (min + fin/dut)

in Progress Pictures 27 upvotes 10 months ago

The user experienced hair thickening and reduced shedding using minoxidil, finasteride, and dutasteride, with a switch from finasteride to dutasteride due to ineffectiveness. They also use a saw palmetto shampoo and take vitamin D3 supplements, while considering potential underlying causes like vitamin deficiencies and hard water buildup.

community Nice product I discovered, thought I would share.

in Treatment 456 upvotes 1 year ago

A product that makes hair look thicker and healthier without promoting regrowth. Discussions include treatments like minoxidil, finasteride, red light therapy, and a serum with caffeine and peptides, with mixed effectiveness opinions.

community Keratin fibers vs. Gossypium Herbaceum Hair fibers

1 upvotes 2 years ago

The conversation is about comparing keratin hair fibers to Gossypium Herbaceum hair fibers for diffuse hair loss. The user prefers keratin fibers for their durability and is seeking a bulk purchase option.

community I use Hair Fibres pretty much everyday, is that okay?

in Product 12 upvotes 1 year ago

Using hair fibers daily is generally fine, but it's important to choose a quality keratin-based product to avoid scalp irritation. The user combines hair fibers with a regimen of finasteride, minoxidil, microneedling, and ketoconazole.

community Using Toppik to fill bald spots while waiting on Finasteride

7 upvotes 3 years ago

User started Finasteride for hair loss and uses Toppik to cover bald spots. They wonder if Toppik's keratin fibers will block follicles and affect hair regrowth.
