Olive Oil- Of all the home remedies for split ends, olive oil was the most effective. It seems there is nothing that olive oil isn’t good for. We found the olive oil to be most beneficial when heated and used as a deep conditioner. All you need to do is heat the olive oil in the microwave, and then massage it throughout your hair. Put a shower cap on, and let the olive oil work into your hair for at least half an hour. After it’s fully soaked into your hair, carefully rinse the product away.
