research Improved two‐dimensional electrophoretic mapping of Japanese human hair proteins; application to curved and straight Japanese human hairs; and protein identification by MALDI MS and MS/MS quadrupole time‐of‐flight mass spectrometry

April 2020 in “International Journal of Cosmetic Science”

This study found that improved protein extraction methods enhanced the resolution of hair proteins on gels, but differences in protein abundance between curly and straight Japanese women’s hair were minimal and unlikely to affect hair structure.

research A genetic electrophoretic variant of high-sulfur hair proteins for forensic hair comparisons. I. Characterization of variant high-sulfur proteins of human hair.

February 1989 in “PubMed”

This study found a genetic electrophoretic variant in high-sulfur proteins from human hair, which was more prevalent in the Japanese samples compared to Caucasian samples, suggesting an autosomal inheritance pattern.

research Electrophoretic variation of hair proteins.

2 citations , November 1996 in “PubMed”

In this study, a "frequent profile" of hair proteins was observed in 180 of 182 individuals, showing consistent electrophoretic bands characteristic of keratins, with rare deviations in two samples.

research Two-dimensional electrophoretic analysis of human hair keratins, especially hair matrix proteins

10 citations , January 1989 in “Archives of Dermatological Research”

The method effectively analyzes human hair proteins, especially nonfilamentous ones.

research Amino Acid Compositions of Human Hair Fibrous Protein Components Purified with Two‐dimensional Electrophoresis

4 citations , December 1989 in “The Journal of Dermatology”

This study suggests that the amino acid composition of fibrous proteins in normal human hair is similar to that of stratum corneum proteins, particularly in cysteine and glycine content.

community CHECKLIST: Blood and other test before starting treatment

4 upvotes 2 years ago

Before starting hair loss treatment, it's suggested to undergo various blood and health tests to minimize side effects. The checklist includes tests for kidney function, liver enzymes, blood sugar, vitamins, hormones, and more.

community Peptides that Stop Hair Loss? | In-depth Literature Review Video

76 upvotes 2 years ago

Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.

community Protein's role in hair growth is more nuanced than just quantity

in Technology 5 upvotes 5 months ago

Protein's role in hair growth is complex, with specific amino acids like cysteine being crucial for effective hair growth. Users discussed using l-cysteine supplements, noting reduced hair loss and faster growth, though some experienced digestive issues.

community Derm told me that my whey protein usage is speeding up hair loss?

26 upvotes 5 months ago

Whey protein is unlikely to cause hair loss, and some users suggest it might be beneficial if dietary protein is insufficient. Hair loss is generally considered genetic, and there is skepticism about the dermatologist's advice to switch from whey protein to whole foods.

community Whey Protein can cause hairloss in men with AGA as per a doctor

64 upvotes 8 months ago

Whey protein may slightly increase hair loss in men with androgenetic alopecia (AGA) due to elevated IGF-1 and testosterone levels, but the effect is minimal compared to treatments like finasteride and dutasteride. Many users argue that whey protein's impact on hair loss is negligible and that maintaining a healthy lifestyle is more important.
