Which Oil is Best to Leave Overnight?

The best oil to leave overnight depends on your needs and whether you're applying it to your hair or skin.

Several oils are excellent for overnight hair treatments. Oils like coconut, olive, and argan are rich in essential fatty acids that repair damaged hair and prevent breakage. Leaving these oils on overnight helps seal in moisture, benefiting those with dry or frizzy hair. However, caution is advised; leaving oil in hair overnight may increase the risk of fungal overgrowth (Reddit discussion on leaving oil in hair overnight).

• Skin type: Select oils suitable for your skin type (e.g., oily, dry, sensitive).
• Patch test: Before applying any new oil to a large area, perform a patch test to check for allergies or adverse reactions.
• Thorough cleansing: Always wash your hair or skin thoroughly after an overnight oil treatment.
