I read all of the wonderful reviews and was anxious to get both this shampoo and the conditioner in the mail. I opened the package, washed and conditioned my hair as usual, and was already disappointed by the time I got out of the shower. I will regularly leave my conditioner on for 5 or more minutes, but doing so seemed to make no difference. I ended up putting a leave-in after I got out and hoped that it would be better the next time. Two days later I tried again with the same results. My hair was so dry. What was worse is that I was in such a hurry that I forgot my leave-in. When I saw my dad he asked me what was wrong with my hair! I reached up and felt it and it had frizzed so badly that it looked like funky straw on top of my head. Unfortunately it also felt like funky straw.
Also, the bottles are small. Really small. With as much hair as I have I'd go through a bottle of conditioner in 2 weeks with all that I'd need to use. That makes this product very much not cost effective for me. I've used expensive shampoos almost my whole life and this has them beat as far as cost.
The fact is that with beauty products there are rarely times when everything will work well for everyone. I love Bumble & Bumble products so I will keep trying until I find one that I fell in love with as much as the invisible oil.
