Verdict

The OGX Thick & Full + Biotin & Collagen Shampoo & Conditioner Set is a solid option if you're looking to add volume and thickness to your hair without worrying about sulfates and parabens. However, the strong scent and potential for dryness might not be for everyone. Users loyal to the previous formula might find the new changes less satisfactory. Consider this set if you're curious about its volumizing claims, but be prepared with a leave-in conditioner to counteract dryness.
