I have just a few staples now, all natural:
1. Shea Moisture Restorative Conditioner: I use it as regular conditioner, deep conditioner, and mixed with aloe juice & jojoba oil as a leave-in. I buy it at Target but I think Walgreens carries it too. I LOVE this stuff. It's about $10 for a bottle that lasts a long time, it's very moisturizing, and I can use it for a lot of different things. (I've also been dying to try the deep conditioning masque from this line but haven't yet.)
2. Nature's Gate Conditioners: They come in a lot of different flavors but all the ones I've tried are good. I use this for co-washes and especially to co-wash out my henna. For some reason it works great for that. Nice and creamy. It's about $6-7 at my Whole Foods.
3. Aubrey Organics GBP Conditioner: I use this mild protein conditioner as a DC every once in a while (like after I texlax), mixed with my Shea Moisture. I think this one is $10-11 at Whole Foods.
4. Terressentials Organic Mud Wash: I've been using this for about a month and I love, love, love it. I can't buy it on the ground but to me it's worth it to order online. I really cleans my hair, no stripping, and leaves it moisturized and relatively tangle-free. It's about $13 a bottle (I think?) and shipping is about $8.50. I order two at a time to offset the shipping cost.
That's it! I've also tried and liked Jessicurl Weekly Deep Treatment and Burt's Bees Avocado Pre-Shampoo Treatment (I don't even know if they make it anymore, it's been a long time).
Hope you find some stuff you like! Hair type and stuff are in my siggy.
