Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Irritation or sensitivity | Very rare | Purified water itself is essentially inert; rare reactions are attributable to contaminants or accompanying ingredients rather than water. |
| Transepidermal water loss aggravation in compromised skin | Rare | Evaporation of water from products may transiently increase dryness in very compromised skin barriers if occlusives are absent. |
| Scalp irritation or redness | Rare | Mild, transient irritation possible at application site, more likely in sensitive individuals. |
| Allergic contact dermatitis | Very rare | Possible sensitization to the botanical extract or accompanying formulation components. |
| Itching | Rare | Localized pruritus reported occasionally with topical scalp products. |
| Contact irritation (redness, stinging) | Rare | Possible in sensitive individuals, generally mild and transient. |
| Mild skin irritation | Uncommon | Transient redness or stinging, more likely at higher concentrations or on compromised skin. |
| Contact urticaria | Very rare | Isolated reports of immediate hypersensitivity reactions. |
| Eye irritation | Uncommon | Can cause irritation on direct contact with eyes, relevant in eye-area products. |
| Skin irritation | Uncommon | Mild redness or stinging, more likely at higher concentrations or on sensitive/broken skin. |
| Contact urticaria (non-immunologic) | Rare | Transient localized hives or itching upon direct skin contact, typically resolving quickly. |
| Pseudoallergic/intolerance reactions | Very rare | Mostly documented with ingestion rather than topical use. |
| Skin dryness or barrier disruption with excessive contact | Uncommon | Frequent or prolonged exposure to water, especially hot or hard water, can disrupt the skin barrier and contribute to transepidermal water loss. |
| Irritation from impurities or hard water minerals | Rare | Reactions are attributed to contaminants, chlorine, or mineral content rather than water itself. |
