The article compares hair oil and conditioner, highlighting their unique roles in hair care. Hair oil primarily nourishes and protects hair by locking in moisture and shielding it from damage, making it ideal for dry or brittle hair. It can be applied to damp hair before styling or as a pre-wash treatment. Conditioner, on the other hand, hydrates and softens hair after shampooing, facilitating detangling and reducing frizz. It should be used post-wash. For optimal results, using both products together is recommended, as hair oil provides nourishment while conditioner offers hydration, promoting overall hair health.
