Redensyl is a cosmetic active complex (containing dihydroquercetin-glucoside/DHQG, EGCG2, glycine, zinc and meta-bisulfite) designed to stimulate hair follicle stem cells and promote hair growth and density. It is marketed as a topical alternative to pharmaceutical hair-loss treatments.
| Reported effect | How often | Notes |
|---|---|---|
Scalp irritation or redness | Uncommon | Mild localized irritation can occur, often related to the formulation base rather than the active itself. |
Contact dermatitis / allergic reaction | Rare | Sensitization to components such as metabisulfite has been reported in susceptible individuals. |
Itching or scalp dryness | Uncommon | Transient and typically resolves with discontinuation or reduced frequency of use. |
Burning or stinging sensation | Rare | Usually mild and short-lived, more likely with higher concentrations or sensitive skin. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
