Does nothing for dry hair
I bought this shampoo in conjunction with the conditioner and the serum.  While I have no issues with the serum, the shampoo and conditioner were a huge disappointment, especially in light of all the rave reviews.  The shampoo did in fact lather nicely and clean my hair, it did nothing for the dryness or color.  In fact, despite being labeled for dry hair, it was significantly a worse performer in this area than even my general-use shampoo.  My hair seemed more dry and had less control / more flyaway hair strands than before use.  (I have used it for two weeks which is ample time to see results). Do not waste your money.
