Glossary Collagen Type VII

protein crucial for anchoring skin layers together

Collagen Type VII is a specific type of collagen protein that plays a crucial role in anchoring the outer layer of the skin (epidermis) to the underlying layer (dermis). It forms structures known as anchoring fibrils, which are essential for maintaining skin integrity and preventing blistering. Defects in Collagen Type VII can lead to a genetic condition called dystrophic epidermolysis bullosa, characterized by fragile skin that easily blisters and tears.

1 citations , May 2024 in “Journal of Dermatological Science”

In this study, KC-AD-MSCs were found to increase COL7 deposition and anchoring fibril formation at the dermal-epidermal junction in a RDEB mouse model, suggesting potential for improving skin integrity in recessive dystrophic epidermolysis bullosa patients.

research Changes in fibronectin, laminin and type IV collagen distribution relate to basement membrane restructuring during the rat vibrissa follicle hair growth cycle.

45 citations , August 1992 in “PubMed”

In this study, researchers found that changes in the extracellular matrix components, particularly fibronectin, laminin, and type IV collagen, during the rat vibrissa follicle growth cycle, suggest dynamic remodeling related to dermal-epidermal signaling.

research Mesenchymal stem cell-derived exosomes promote scalp rejuvenation through type XVII collagen regulation via the miR-21-5p/DKK2/Wnt pathway

April 2026 in “Frontiers in Cell and Developmental Biology”

This study found that exosomes from human umbilical cord mesenchymal stem cells reduced hair follicle aging and promoted hair regeneration in models by upregulating COL17A1 through the miR-21-5p/DKK2/Wnt/β-catenin axis, outperforming existing treatments like minoxidil.

research Regenerative Hair Pigmentation via Skin Organoids: Adaptive Patterning Mediated by Collagen VI and Semaphorin 3C

July 2025 in “Advanced Science”

A user shared their positive experience with a hair transplant at Wimpole Clinic, performed by Dr. Malkani, and discussed using finasteride at a reduced dose due to side effects. They also mentioned avoiding minoxidil due to heart pain and taking supplements like biotin, marine collagen, viviscal, and krill oil.

community Collagen peptides: Yay or nay?

5 upvotes 6 years ago

Collagen peptides may help with hair growth, but results vary; some users noticed less hair fall and improved nail strength. Minoxidil is suggested for regaining hair thickness lost from accutane.

community Collagen peptides(powder) i highly recommend

7 upvotes 1 year ago

Collagen peptides are recommended for hair and skin benefits, with users noting improvements in hair and skin health. However, evidence on their effectiveness for hair growth is inconclusive.

community Summary of Procapil video by Haircafe

2 upvotes 1 year ago

Procapil is marketed as a natural hair loss treatment but lacks strong evidence and is industry-biased. Minoxidil and Finasteride are the only FDA-approved treatments for androgenetic alopecia.
