Acetyl Tetrapeptide-3 for Hair Growth
Acetyl Tetrapeptide-3, also known as Folixyl® or Capixyl®, is an anti-hair loss peptide derived from a growth factor. It plays a key role in stimulating hair growth by promoting the synthesis of collagen and laminin within the hair follicle. Because these structural proteins are important for strengthening the follicle, also supporting healthier and fuller hair.
Capixyl Peptide Anti-Hair Loss Mechanism
This active ingredient works by:
- Enhancing collagen I and III synthesis to reinforce hair follicle anchoring.
- Stimulating laminin to improve cell structure and follicular stability.
- Supporting dermal papilla renewal to combat the stiffening of hair follicle sheaths — a common cause of hair thinning and loss.
Clinical studies have shown Capixyl peptide anti-hair loss activity by increasing hair density in as little as 7 days, therefore outperforming other common treatments.
Folixyl Peptide Benefits for Skin
In addition to its scalp benefits, Folixyl peptide also supports skin rejuvenation:
- Enhances extracellular matrix support.
- Promotes cell adhesion and tissue repair.
- May improve elasticity and firmness in topical applications.
Capixyl vs Minoxidil Hair Regrowth
In clinical comparisons:
- Capixyl was shown to offer faster visible results in hair density.
- Unlike Minoxidil, Capixyl works by improving follicle structure naturally without hormonal interference.
- Capixyl is better suited for sensitive scalps due to its low-irritation formula.
