Dermaroller - Hair Growth Stimulator

This Derma roller is a handheld percutaneous collagen induction (PCI) device designed for advanced scalp and skin therapy. It features an ergonomic handle equipped with a rotating cylindrical barrel embedded with 540 ultra-fine, medical-grade titanium micro-needles measuring 1.00 mm in length.

Clinical Mechanism: How Microneedling & Hair Oils Work Synergistically

The scalp's primary outer barrier, the stratum corneum, significantly limits the absorption of topically applied compounds. Combined therapy with 1.00mm needles works via two main pathways:

1. Transdermal Microchannel Formation (Enhanced Delivery)

• Deeper Micro-Pathways: At 1.00 mm, the micro-needles fully pass through the epidermis and penetrate deeper into the dermis layer.

• Maximized Bioavailability: Creating these deep, physical micro-channels circumvents the stratum corneum barrier, allowing bioactive compounds in topical hair oils (such as castor, peppermint, or rosemary oils) to bypass skin surface resistance and reach deep hair follicle bases.

2. Physiological & Cellular Cascades (Follicle Activation)

• Enhanced Growth Factor Release: Micro-injuries at the 1.00mm depth trigger a robust wound-healing cascade. Platelets release critical signaling proteins—including Vascular Endothelial Growth Factor (VEGF) and Platelet-Derived Growth Factor (PDGF)—which promote local microvascular circulation and oxygenation around dormant hair follicles.

• Follicle Phase Transition: Mechanical stimulation triggers stem cell activity in the follicle bulge area, signaling hairs to exit the resting (telogen) phase and enter the active growth (anagen) phase.

• Nutrient Synergism: As local vasodilation and tissue remodeling occur, the deeply absorbed oils supply targeted essential fatty acids, antioxidants, and anti-inflammatory compounds directly to the active dermal target zones.

Usage & Clinical Protocol Guidelines

1. Sanitization: Disinfect the derma roller with 70% isopropyl alcohol before and after every session.

2. Application Order: Gently roll the device across the targeted scalp areas in four directions (horizontal, vertical, diagonal) applying light-to-moderate pressure. Apply topical hair growth oils immediately afterward to take advantage of the open micro-channels.

3. Frequency: Because 1.00 mm needles penetrate deeper into the dermal tissue, use the device only once every 7 to 10 days (or once every 2 weeks). This extended interval gives the deeper scalp tissue adequate time to complete its structural repair and collagen remodeling phase safely.
