Other forms: conditioners
Conditioner is a cream that softens hair after washing. Rinse out the conditioner, leave-in conditioner, shampoo and conditioner.
Shampoo strips the oil and conditioner puts something back, coating the hair so it lies flat and combs without tearing. Fabric conditioner does the same job for cloth, and an air conditioner is a different sense of the word entirely.
