This is the same pathway broadly implicated in dermal papilla cell regulation across the hair-biology literature, and it's worth being precise here: the connection between GHK-Cu and follicle-specific Wnt activation is still an area of active study rather than settled fact, and most of the strongest data so far comes from cell culture and animal models rather than large human trials
Reported side effects are typically mild and may include: Mild nausea (usually with oral forms) Temporary dizziness Gastrointestinal discomfort Injection site reactions (with injectable form) Most users report no significant side effects, making it an attractive option for those concerned about adverse reactions to traditional medications
