I initially used Neil George Intense Illuminating Conditioner with the shampoo from the same line. Eventually, I ditched the shampoo (I didn't like it; it seemed to leave my hair greasy) but used the conditioner to its last drop.
This product consistently left my highlighted hair exactly as promised -- smooth, luxurious and tangle-free. Plus, a little goes a long, effective way. By conditioning my hair every other day, one bottle lasted three months.
Bottom line: Skip the shampoo, but splurge on this conditioner -- it's excellent. The product sells for $24 at C.O. Bigelow, Easton Town Center. --Kristy Eckert
