research Protein disulphide isomerase-mediated grafting of cysteine-containing peptides onto over-bleached hair
PDI helps restore over-bleached hair's strength and structure by attaching special peptides.
research Characterization of a gene encoding a cysteine-rich keratin associated protein synthesized late in rabbit hair follicle differentiation
A rabbit gene important for hair development was identified and detailed.
research Characterisation of an Ovine Keratin Associated Protein (KAP) Gene, Which Would Produce a Protein Rich in Glycine and Tyrosine, but Lacking in Cysteine
A new sheep gene, KRTAP36-1, may help breed sheep with better wool by reducing prickle factor.
research Isolation and characterization of genomic clones of human sequences presumably coding for hair cysteine-rich proteins
A new protein linked to hair strength was identified, aiding in understanding brittle hair conditions.
research Application of XANES profiles to X-ray spectromicroscopy for biomedical specimens: Part II. Mapping oxidation state of cysteine in human hair
Perming and bleaching damage hair differently, with bleached hair having more cysteic acid in the cuticle.
research Characterization of transport systems for cysteine, lysine, alanine, and leucine in wool follicles of sheep
Sheep wool follicles absorb different amino acids at various rates and locations, which could affect wool growth based on diet and genetics.
research Determination of Cystine and Cysteine in Altered Human Hair Fibers
Cold waving solutions quickly reduce cystine to cysteine in hair.
research Cystine-thiamin-containing hair-growth formulation modulates the response to UV radiation in an in vitro model for growth-limiting conditions of human keratinocytes
A hair-growth formula with cystine and thiamin helps protect skin cells against UV damage and improves their growth.
research Xenobiotics in Vitro: The Influence ofL -Cystine, Pantothenat, and Miliacin on Metabolic and Proliferative Capacity of Keratinocytes
L-cystine, D-pantothenat, and miliacin together significantly boost keratinocyte growth and metabolism.
research The Influence of Electrode Potentials on the Extent of Reduction of Cystine in Hair Fibers by Reducing Agents
The effectiveness of reducing agents on hair fibers depends on their electrode potentials.
research Dissecting hair breakage in alopecia areata: the central role of dysregulated cysteine homeostasis
Disrupted cysteine metabolism may cause hair breakage in Alopecia Areata, suggesting potential treatments like N-acetylcysteine.
research Cysteine and Glutamine level in hair shaft fractures patients
Cysteine strengthens hair, and glutamine fuels hair growth.

Amino acid supplements may not be necessary for all women with chronic hair loss.
research Isolation and characterization of a sheep cysteine-rich cuticle keratin pseudogene
Researchers found a non-functional sheep keratin gene due to mutations.
research Efficacy of Oral Supplementation with Serenoa Repens, Pumpkin Seed Extract and Cysteine Combined with Topical Minoxidil 5% Vs Topical Minoxidil 5% Alone in Androgenic Alopecia A Randomised Assessor-Blinded 6-Month, Superiority Trial
Combining supplements with minoxidil improves hair growth more than minoxidil alone.
research Reconnection of cysteine in reduced hair with alkylene dimaleates via thiol‐Michael click chemistry
A new method using 1,4-n-butylene dimaleate effectively repairs and strengthens damaged hair.
research Comment on 'A prospective real world study evaluating serum levels of arginine and cysteine in females with chronic telogen effluvium: do we really need blanket prescription with amino acid supplementation?'
