Originally prescription only in our dermatologist’s office, this hair loss serum uniquely contains Copper tripeptide, a novel molecule that stimulates hair growth. Clinically proven to have similar efficacy to that of 5% minoxidil, stimulating growth without irritation side effects or toxicity. Studies show collagen production is increased, strengthening existing hair and thickening the hair shaft.


[Intensive] Apply 5 drops on the whole scalp twice daily.

[Maintenance] Apply 3 drops on the whole scalp twice daily.


[Once a week] Place the gel cap into the heated mask bar for 10 minutes. While the gel cap is heating up, apply 20-30 drops of Copper Peptide Hair Regrowth Serum using the click open built-in applicator on the scalp to stimulate hair growth. Take this opportunity to give yourself a relaxing head massage using a rose roller for increased serum absorption. After 10 minutes, take the gel cap out of the mask bar and wear it for 15-20 minutes. Be sure to test temperature before use to avoid scalding.
