This gives incredible body but hair gets greasy pretty quickly. The travel size is ridiculously over priced.Been using the Full Shampoo and Conditioner a few weeks. Was recently diagnosed with Telogen Effluvium and wanted to try the one month supply of these items before going on to their other products. It's really nice shampoo and conditioner. Lathers really well. Smells nice. My gray hair came out shiny and soft. As I used it more, my hair seemed to get a bit fuller which is really important at this time. It's pricey for sure but given my situation, if it's works I'm willing to pay the price. Have definitely gotten better results than using the bigger name, pricier salon products. Maybe its the keratin, I don't know, but I'm happy with the results so far.I ordered the travel size for my vacation and was disappointed that the bottles were half full and also that they did not have any covers to remove. Will not purchase this shampoo again. I have used the full size in past. Shampoo is not worth the cost.The smell is strong & musky. The general feel of it in your hair is globby & slimy - had trouble working it into a lather. Very disappointed. Jennifer Garner backs this line - but she must not care that it stinks.This shampoo made my hair flat with no volume at all. Could just be the type of hair that I have.Very good shampoo, my hair feels so clean and soft.I love this product!! I have fine hair that has not been doing well thanks to female hormones and this, plus the conditioner have made my hair incredibly soft. A little goes a long way too! I also have the full size, but this is great for travel.I’ve got poker straight hair that needs volume and this shampoo delivers (and then some!) best volume shampoo ever
