If you're looking for something more budget-friendly I can recommend the Nature's Gate conditioners. I've liked almost all that I've tried, my favorite being the Chamomile, Herbal (strong smell) and Jojoba one. I haven't tried the Biotin one but that one looks good. That one has the most amount of protein I think. I've found them at Whole Foods for around $6.50 or you can get them on iherb.com for $5-$7. Search - nature's gate conditioner - iHerb.com
If you've never ordered from iherb.com before you can also use my discount code, it's in my siggie! It's $5 off any order under $40 or $10 off for orders over $40.
I do like the NG conditioners. I think they're high quality for a good price.
