They're dormant, waiting for the right signal to wake up and start producing healthy hair again

Blots were incubated overnight at 4 C with HRP-conjugated anti-nitrotyrosine mouse mAb (1:2500 dilution in CanGetSignal solution 1,NKB-101, Toyobo, Osaka, Japan), followed by ECL-detection on a FUSION SOLO.7S.EDGE imaging system (Vilber Lourmat, Marne-la-Valle, France)

Furthermore, as mentioned (Luetic et al., 2017

Unlike harsh chemical ingredients that can cause irritation or damage, GHK-Cu is gentle enough for all hair types, including sensitive scalps, and has been proven safe and effective in numerous clinical studies
