The Science of holi (growth): How Copper Peptides, Redensyl, Spermidine, and Botanicals Support Stronger, Fuller Hair

Healthy, radiant hair starts at the scalp. At Agent Nateur, we believe beauty rituals should merge ancient wisdom with modern science. holi (growth) was formulated to awaken hair at the root, protect the follicle, and nourish both scalp and strands with a symphony of clinically studied actives and plant extracts.

Here’s a look at the hero ingredients that make holi (growth) so effective:

Copper Peptides: The Cellular Rejuvenator

  • What it is: Copper Tripeptide-1, a naturally occurring peptide found in the body.
  • Why it matters: Copper peptides stimulate fibroblasts and increase blood flow to the scalp, supporting stronger, thicker hair. They also encourage collagen and elastin production, which helps maintain scalp health and elasticity.
  • Benefits: Revitalizes dormant follicles, reduces breakage, and promotes denser hair over time.

Redensyl: Awakening the Follicle

  • What it is: A patented complex featuring Larix Europaea Wood Extract (from larch) and Camellia Sinensis (green tea) extract.
  • Why it matters: Redensyl targets hair follicle stem cells and fibroblasts, reactivating growth while reducing hair fall. In clinical studies, it has shown results comparable to traditional hair-loss treatments, without harsh side effects.
  • Benefits: Encourages new growth, increases hair density, and visibly improves thinning areas.

Spermidine: Cellular Longevity for Hair

  • What it is: A polyamine compound found in plants and whole foods, now researched for its anti-aging properties.
  • Why it matters: Spermidine supports autophagy (the body’s natural cellular renewal process), protecting hair follicles from premature aging. It helps maintain the growth phase (anagen) of the hair cycle, leading to longer, healthier strands.
  • Benefits: Prolongs hair growth, reduces shedding, and improves scalp vitality.

Botanical Allies

Rosemary

A time-honored remedy for hair vitality, rosemary oil stimulates circulation to the scalp, helping deliver nutrients to follicles. It’s also known for balancing sebum production and soothing scalp irritation, creating the ideal environment for strong growth.

Astragalus

This adaptogenic root, revered in traditional Chinese medicine, is rich in antioxidants and polysaccharides. Astragalus helps combat oxidative stress at the follicle level and supports resilience, both of which are essential for maintaining healthy hair in the face of modern stressors.

The Supporting Cast

Each element is carefully chosen to create synergy:

  • Cucumber Extract & Glycerin → hydrate and refresh the scalp.
  • Zinc & Glycine → essential cofactors for keratin and collagen production.
  • Milk Proteins & Inositol → strengthen hair fibers from root to tip.
  • Botanical Oils (Jasmine, Ylang Ylang, Sandalwood, Copaiba, Lavender, Peppermint) → provide sensorial luxury while calming, nourishing, and balancing the scalp microbiome.
