Applying Tendrone 1% (hydrocortisone 1%) lotion on a baby's head can be safe, but it should only be done under the direct supervision of a pediatrician. An infant's skin is thin and sensitive, which increases the risk of absorbing the medication into their system. If your doctor has prescribed this, apply a very thin layer only to the affected area, taking care to avoid the eyes. If it has not been prescribed, please consult your pediatrician before use. They can safely diagnose the scalp condition, such as cradle cap or baby eczema, and recommend the most appropriate and gentle treatment.
