My hair has been feeling quite porous and fragile after a series of dye experiments so I really needed a product like this. I spray this all over on my damp hair and comb it through, then style. Unexpectedly, this makes my hair very straight without the aid of a straightener (I have naturally wavy hair). After a couple of weeks, I feel my hair is regaining some of its strength and some of my problem areas (rubbery hair) are not so noticeable. I do not use this in conjunction with any other Chi products, just my own favorite shampoos and conditioners. I use other products to give my hair shine and for anti-frizz.
