I don't regularly use honey, other than in my pt every couple of weeks. It's moisturizing, a humectant, and helps increase shine. Used in flaxseed gel, it increases hold. You can add a bit to your conditioner as well, for a little increased moisture, or do the same and add an oil or other moisturizing ingredients for a homemade dt. Mixed with water, it does produce a small amount of natural peroxide, so if you decide to use it regularly and are worried about lightening your hair, zap it in the microwave for a few seconds. Warming it up neutralizes the peroxide.

Coconut oil is one type of oil that can absorb into the hair cuticle. Though it isn't a protein itself, it does increase the hair's ability to retain protein. So, if you're protein sensitive, it can mimic the effect of a protein.

My hair seems to hate straight oils, so I haven't used grapeseed. However, it's a lighter oil that many like to use to seal. It works for some finer haired people where heavier oils weigh them down.
