This product was very hyped about and I am a fan of dry shampoos that are effective for longer than one day. Unfortunately I must have been allergic to something in this formula because although it worked, soaking up oils and leaving my hair with a workable texture, my scalp was very irritated. I had to take it back to Sephora because for 30$ (or any price!) I was not going to use something that was uncomfortable to use.
