Beyond that landmark study, the evidence base includes research showing GHK-Cu enlarges hair follicle size, extends the anagen (active growth) phase, stimulates dermal papilla cells (the cells that control follicle activity), promotes angiogenesis (blood vessel growth) to the scalp, and reduces the DHT-related inflammation that causes follicle miniaturization in androgenetic alopecia
It depends on your baseline
It actively inhibits the activation of Nuclear Factor kappa B (NF-B), a master transcription factor that resides in the cytoplasm of cells
It has been widely studied in preclinical models for its potential to support tissue regeneration , angiogenesis , and inflammation modulation
It has also been discovered that the chromophore phycocyanobilin (PCB), which is abundant in cyanobacteria and blue-green Spirulina like Spirulina , severely inhibits this enzyme complex (Abu-Taweel et al
But is there evidence to back up these claims
