Cheap conditioner

TRESemme Radiant Volume is a collection from the Naturals part. Its conditioner contains orange and lemongrass to help give your hair lots of strength and shine, without weighing you down (see title link). Also has coconut oil and is silicone-free.

Strong hair

If you want strong hair, try sweet orange in a natural spray that adds volume and hold. Tresemme Naturals Finishing Spray contains aloe vera and avocado to moisturize your hair and is even non-aerosol. It's extremely lightweight so you don't feel made up, and the extracts are all organic. Humidity-resistant and dye free, it helps your hair get that natural shine. It's available online for $5.49 (see title link), but I found it at the drugstore for $4.
