Quality Control
Each batch is tested under strict QC procedures including:
Identification test → Confirms chemical structure (positive result required)
HPLC assay test → Purity control (target 99% with batch result 99.35%)
Heavy metals (ICP-MS) → ≤20 ppm (result: 5 ppm)
Residue on ignition → ≤0.5% (result: 0.06%)
Loss on drying → Controlled moisture content (0.16%)
Organic volatile impurities → Compliant with pharmacopeia standards
Microbial limits
Yeast & mold: <100/g (result <10/g)

Mechanism of Action
Minoxidil works through multiple biological pathways:
Vasodilation
Improves scalp microcirculation, increasing oxygen and nutrient delivery to hair follicles.
Follicle Activation
Stimulates dermal papilla cell activity and promotes follicle regeneration.
Growth Phase Extension
Prolongs anagen (growth phase), delaying transition into catagen/telogen phases.
Follicle Enlargement
Increases follicle size, resulting in thicker and denser hair strands.
