Common side effects
- Scalp irritation, itching, dryness, or burning
- Changes in hair texture or oiliness

Important warnings
- For external use only; avoid contact with eyes and broken skin.
- Stop use and seek medical help for swelling, breathing difficulty, or a severe rash.
- Persistent or worsening symptoms may need medical assessment.
- Follow the product label; treatment schedules can vary by condition.
Pregnancy
Scalp absorption is low, so significant exposure is unlikely; available evidence has not identified a clear risk.
Breastfeeding
Scalp use is unlikely to expose a breastfed infant significantly. Avoid applying to the breast or allowing infant contact with treated skin.
Interactions
- Interactions are unlikely with shampoo use because little medicine enters the bloodstream.
- Tell a clinician about topical or oral steroid use; stopping steroids suddenly can worsen scalp inflammation.
