Unlike pattern baldness, this represents physical injury rather than biological process

This represents a massive increase in bioavailability, potentially elevating topical applications to levels approaching injectable delivery

Optional addition: Weekly microneedling with topical GHK-Cu on non-injection days for combined systemic and local effects

GHK-Cu alone provides regenerative peptide signals that support follicle function

For GHK-Cu specifically, some researchers prefer morning administration to align with natural growth hormone patterns

Genetic factors affecting receptor expression or downstream signaling may limit effectiveness
