In hair care, peptides help support the growth phase of the hair cycle, strengthen follicle structure, and promote a healthy scalp environment for fuller-looking hair.
Selected for their specificity and biological relevance, peptides allow for targeted support at the follicle level while mimicking natural processes in the body.
Peptides are short chains of amino acids—the building blocks the body uses to create essential structures and functions. While amino acids form larger proteins, smaller peptide chains act as powerful biological messengers.
Because of their size and structure, peptides can interact with cells to regulate key processes such as repair, regeneration, inflammation balance, and cellular signaling. Naturally occurring peptides play important roles throughout the body, from hormone regulation to tissue structure and antioxidant defense.
In recent years, peptides have gained attention in medical and aesthetic applications due to their ability to mimic and enhance natural biological processes. When applied topically in scalp care, specific peptides help support the environment around the hair follicle—promoting stronger, healthier-looking hair and helping to optimize conditions for growth.
Peptides are powerful molecules that help stimulate hair growth, strengthen follicles, and improve scalp health. They support the hair cycle, prolonging growth phases and slowing shedding, while promoting collagen and keratin production to make hair thicker and stronger. Some peptides also reduce inflammation, protect against DHT, and improve blood flow to the scalp, creating the ideal environment for fuller, healthier hair.
Plant stem cells are undifferentiated cells found in growth regions of plants, such as roots and buds. Like human stem cells, they support growth and repair—however, unlike human cells, they remain active throughout the plant’s lifespan.
While plant stem cells do not function as human stem cells in the body, their value lies in the powerful bioactive compounds they produce. Through specialized harvesting and culturing, these cells yield concentrated antioxidants, peptides, polyphenols, and growth-signaling molecules. These compounds help protect against oxidative stress, support circulation, and promote healthy cellular function—all with a strong safety profile.
At Deeply Rooted Hair Lab, we believe healthy hair begins at the root—and that meaningful results come from respecting the biology beneath the surface.
