haven't heard about olive oil. but my mom said mayonnaise won't do anything for your hair except make you smell like a sandwich. i don't care if it works, it's messy and yucky
I love those little deep conditioning tubes that come in my home hair coloring kit from Loreal... are there any deep conditioners on the market right now that are comparable? If I don't find a good one soon, I'll have to resort to ebay since I use the tubes up way faster than I color my hair.
