GHK-Cu, also called copper peptide, may support hair growth by encouraging follicle signaling and improving blood flow to the scalp. It’s one of the most researched peptides in cosmetic dermatology and is also valued for its skin-supportive properties.

In topical use, GHK-Cu may help even out skin tone and reduce the appearance of dark spots by supporting healthy cell turnover and calming discoloration—benefits that extend to the scalp as well as the face.

That said, results can vary from person to person. GHK-Cu tends to show the most benefit when used consistently as part of a broader hair care routine, rather than on its own for those experiencing significant thinning.

Zinc thymulin is a peptide-mineral complex that combines zinc and thymulin, a peptide originally linked to thymus gland activity but also found in the skin and hair follicle structures.

In lab studies using cultured human hair follicles, thymulin was shown to support hair shaft elongation and extend the anagen (growth) phase—suggesting its potential to promote healthy hair cycling at the follicular level. Zinc, in this context, helps stabilize thymulin and contributes to scalp health by regulating enzymes associated with hair shedding.

Peptide-based compounds like zinc thymulin are often part of a broader wellness routine. When paired with balanced nutrition, scalp care, and consistent topical use, they can support long-term hair and skin health.
