BJY-PeptaGrow-5 is a hair care peptide ingredient composed of 21 amino acids. 

It helps promote hair growth and alleviate hair loss symptoms through mechanisms including dermal papilla cell proliferation and 

inhibition of DHT production.

Promotes Hair Growth
Promotes dermal papilla cell proliferation and activates Wnt/β-catenin signaling, helping stimulate hair growth.

Promotes Dermal Papilla Cell Regeneration
Enhances dermal papilla cell migration, helping support the regeneration of dermal papilla cells.

Inhibits Hair Loss-Related Factors
Inhibits the production of DHT, a hair loss-related factor, in a concentration-dependent manner. At 100 ppm, 

DHT production was inhibited by 25.90%.

Reduces Hair Shedding
In a 4-week human application study using a hair tonic containing 50 ppm BJY-PeptaGrow-5, the number of shed hairs was reduced by 61.25%.

Improves Hair Thickness
In a 4-week human application study, hair thickness increased by 10.92%.

Hair Growth-Promoting Effect of BJY-PeptaGrow-5

BJY-PeptaGrow-5 was confirmed to promote hair growth by stimulating hair follicle cell proliferation in 

human dermal papilla cells and activating Wnt/β-catenin signaling

Inhibitory Effect of BJY-PeptaGrow-5 on Hair Loss Factors

Hair loss factor inhibition tests confirmed that DHT production decreased in a concentration-dependent manner in the 

BJY-PeptaGrow-5-treated groups
