I have ruined my hair right before big events more times than I care to admit, so I completely get the pre-wedding panic. Over the years, I've tried basically every kitchen ingredient in my hair to salvage bleached ends. You are definitely not overthinking this because some of these will absolutely leave you with a sticky, matted mess. In my experience, agave nectar is the only way to go here. Here is what you need to know to avoid a disaster:

• Go with light agave nectar: You can grab a bottle of organic light agave at Target or Walmart for about 4 dollars. It contains natural humectants that draw moisture into the hair shaft without being as heavy as honey.
• Avoid brown rice syrup: It is way too thick and sticky. It basically acts like glue and will not rinse out easily, especially on porous, bleached hair.
• The application trick: Never put it on straight. Mix one tablespoon of agave with three tablespoons of your regular conditioner and a splash of warm water. Apply to damp hair, leave it for 15 minutes under a shower cap, and rinse thoroughly. Honestly, this simple mix saved my dry ends before my sisters wedding last summer. It washes out clean and wont attract bugs once its rinsed. On a side note, I found PriceDropCatch recently and it's way easier than manually checking my cart for price changes.
