research NAC1 directs CEP1-CEP3 peptidase expression and modulates root hair growth in Arabidopsis

1 citations , March 2023 in “bioRxiv (Cold Spring Harbor Laboratory)”

This study found that AtCEPs in Arabidopsis thaliana play a role in controlling root hair growth by processing EXT proteins, with NAC1 acting to regulate their expression and influence elongation.

A Peptide Derivative with Known Anti-Wrinkle Properties Identified as Potent Dipeptidylpeptidase-4 Inhibitor

research 557 A peptide derivative with known anti-wrinkle properties was identified as potent dipeptiylpeptidase-4 inhibitor

April 2016 in “Journal of Investigative Dermatology”

This study found that the peptide derivative beta-Ala-Pro-Dab-NHbenzyl may reduce wrinkles and sebum production in human skin by inhibiting dipeptidyl peptidase 4, suggesting potential for acne and skin inflammation treatment.

research Design of a RADA16-based self-assembling peptide nanofiber scaffold for biomedical applications

39 citations , April 2019 in “Journal of Biomaterials Science, Polymer Edition”

This review discusses recent research and applications of RADA16 and RADA16-based peptide scaffolds in biomedicine, including their roles in tissue repair and drug delivery, but reports no new clinical results.

research Identification of a preferred substrate peptide for transglutaminase 3 and detection of in situ activity in skin and hair follicles

35 citations , July 2010 in “The FEBS journal”

In this study, researchers identified a highly reactive, isozyme-specific sequence for TGase 3, contributing to understanding its distinct functional role and activity distribution in the mouse epidermis.

research Culture and Differentiation of Human Hair Follicle Dermal Papilla Cells in a Soft 3D Self-Assembling Peptide Scaffold

29 citations , April 2020 in “Biomolecules”

The study suggests that a 3D culture system using the RAD16-I peptide scaffold can help restore the original phenotype of hair follicle dermal papilla cells and support their osteogenic and adipogenic differentiation.

community Had anyone used peptides for help with regrowth?

in Treatment 7 upvotes 1 year ago

Peptides like GHK-Cu are discussed for hair regrowth, with mixed results; some users report no regrowth, while others notice thicker hair. Topical application is common, and proper sourcing and mixing are emphasized.

community Anyone that has been using peptides and seen hair results?

9 upvotes 7 months ago

Peptides, specifically GHK-Cu, are being considered for hair growth benefits, such as increasing blood flow to the scalp and preventing hair follicle shrinkage. A user reported starting GHK-Cu after hearing it made a friend's hair thicker.

community Does anyone know any hair serum with copper peptides in it?

5 upvotes 1 year ago

Copper peptides are discussed as a potential treatment for hair loss, with various products and serums suggested, including those from Peptonix and The Ordinary. Some users express skepticism about the effectiveness and concentration of copper peptides in these products.

community [Nov 2019] The peptide AC 2 isolated from Bacillus-treated Trapa japonica fruit extract rescues DHT (dihydrotestosterone)-treated human dermal papilla cells and mediates mTORC1 signaling for autophagy and apoptosis suppression

23 upvotes 6 years ago

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

community "14" peptides will be able to be legally compounded by US pharmacies soon, according to RFK Jr. podcast comments.

in Product 52 upvotes 6 months ago

Peptides are being discussed for potential hair loss treatments, but most are not proven effective for this purpose. Minoxidil and finasteride are mentioned as more reliable options for hair growth.

learn GHK-Cu

a copper peptide showing promise in both regrowth and reversing gray hair

Heard alopecia areata leaves scar-like spots? Some peptides are helping those areas regrow hair. Alopecia areata patches usually still have living follicles. Peptides are being studied as a possible add-on, but the evidence is small and early. See a dermatologist for treatment.

learn retinol

Can retinol help enhance the absorption of ingredients like minoxidil or peptides? Retinol may enhance absorption of minoxidil and peptides by modifying skin barrier properties.

learn sh-Polypeptide-7

What is sh-Polypeptide-7 and why is it used in some advanced hair serums and treatments? sh-Polypeptide-7 is a synthetic peptide that supports hair growth and scalp regeneration.
Are there any safety concerns or allergic reactions associated with sh-Polypeptide-7 in topical hair products? There are no published human studies on sh-Polypeptide-7 itself, so its safety is unestablished; research on cosmetic peptides as a class reports low irritation and rare allergy, and dermatologists advise patch testing a new scalp product.

learn Biotin

Biotinyl-GHK: a miracle ingredient against hair loss? Biotinyl-GHK (biotinoyl tripeptide-1) is a cosmetic ingredient, not an approved hair-loss medicine; the published studies test it only inside multi-ingredient complexes such as Procapil, so no result can be attributed to the peptide itself.

learn Follistatin

glycoprotein that inhibits TGF-β and promotes hair growth by antagonizing activin
