i am also really into trying to use only natural products on my hair/face/body, and have been trying out a bunch of different brands. i've had good experiences with the nature's gate products. i used their biotin strengthening conditioner if my hair needs protein, but i use their aloe vera conditioner everyday. i drench my hair with it, and leave a little in, and you can feel it plump up your hair. it also never leaves my hair feeling weighed down/greasy, and really moisturizes it. i also use aubrey organics honeysuckle rose as i need it, and while heavy, does a great job as a deep treatment, or as a rinse out. i actually don't like the smell of honeysuckle though, so i'll be trying a different conditioner of theirs once i run out.
and i wash my hair everyday with a chagrin valley shampoo bar. i did not like the mud and clay one, but that was my first bar, and my hair had to transition. so far i really like the summer sunshine, and the herb garden is ok. i've also never used an apple cider vinegar rinse after the shampoo bar, b/c i can't deal with the smell or the idea of putting it on my hair, and my hair has adjusted to using them just fine. i never feel any residue/etc afterwards, and my hair never feels dry. it just feels soft and clean. i recommend getting the gift sizes, which are better than the sample sizes b/c they're not cut into weird shapes. i'm also searching for other brands of shampoo bars to try out too, just to see whats out there.
but chagrin valley's products have been great so far. if you're looking to get away from sulfates, but are afraid that the conditioner washes will be too heavy on your hair, then the shampoo bars are a great way to go, especially if you have finer hair. i want a lot of volume in my hair, and so thats what turned me onto the shampoo bars over the co-washes. and i use a conditioner after it, one without silicones, and my hair has been looking pretty good. and i use deva products for styling, b/c they're water soluble, so it doesn't take a harsh shampoo to get them out. hth!
