Hair Growth Serum — KGF, Caffeine & Peptides | WhollyKaw
DESCRIPTION
KGF or Keratinocyte Growth Factor + caffeine + saw palmetto — three follicle activating mechanisms in one serum. No alcohol and no silicone. 50ml airless pump. Beard and hair care serum that include peptides, amino acids, vitamins and moisturizing components.
Hair loss has one primary driver: DHT (dihydrotestosterone) binding to follicle receptors and shrinking them over time. This serum targets that process from three independent angles simultaneously.
Caffeine - penetrates the follicle and directly counteracts DHT's suppressive effect on hair fiber growth.
Saw Palmetto- inhibits 5-alpha-reductase, the enzyme that converts testosterone to DHT, blocking production upstream
KGF (Keratinocyte Growth Factor) - a bio-identical growth protein that stimulates follicle differentiation and promotes the anagen (active growth) phase. Present in fewer than 5% of commercial hair serums.
Supporting cast: Biotin (keratin structure), Maca Root (Wnt/β-catenin pathway activation), Polypeptides (cellular growth signals).
No alcohol. No parabens. No silicone.Â
| Ingredient | Mechanism | What It Targets |
|---|---|---|
| KGF (Keratinocyte Growth Factor) | Bio-identical growth protein — stimulates follicle differentiation | Hair thickness, density, and length; anagen phase extension |
| Caffeine | Counteracts DHT suppression at the follicle level | Hair fiber diameter and growth speed |
| Saw Palmetto | Inhibits 5-alpha-reductase — blocks DHT production | DHT-driven follicle miniaturization |
| Polypeptides | Bio-identical proteins stimulating cellular growth signals | Follicle differentiation and regeneration |
| Biotin | Improves keratin infrastructure | Follicle activation and structural integrity |
| Maca Root Extract | Activates Wnt/β-catenin pathway | Maintains anagen phase duration |
Â
Size: 50 ml or 1.69 fl. oz. airless pump
Science
Science backed beard and hair care product to:
- Promote hair growth
