Tresseme's rendition of the dry shampoo left much to be desired in my experience with it. I had used it just as my hair started feeling slightly oily and to my dismay it actually looked like I had dandruff flakes. I had to wash it off the next day and it did not perform as it claimed to as my hair felt dirty oily and full of dandruff!!! Unfortunately this isn't one that I'll be purchasing again
I'm really not a big fan of this dry shampoo. It merely absorbs the oil, from the dirt. I don't know if it's all in the mind but it actually makes me hair feel dirtier. I have this in my ICE (in case of emergency) stash. I don't use it unless I really, really have to. So this can has lasted me more than 6 months. They say don't spray too much because a white residue will form, in my opinion, this white residue forms rather easily.
I have really thick hair and it takes a lot of maintenance for it to look good, and like most of us, I get lazy days where I don't wash my hair. This helps! BUT, I would recommend washing your hair after using this for a day. It takes away the oily look, but to me, my hair still doesn't feel clean. You also have to make sure you rub it all in at the roots otherwise it will show.
