It was an alright product. I don't straighten my hair often because it's very fine and very prone to damage. The spray is a bit too heavy for my hair and makes it look a bit greasy. I have no doubt that it works well for other people but for my particular hair type it isn't helpful.

I don't use heat that often on my hair so I can't really vouch for it's protecting property. I find it does leave residue when I do use it, my hair feels kind of rough, almost sticky. I have a lot of hair which is also very thick so I just spritz until it was coated. I thought I was using too much so I tried less but didn't feel like I got all my hair, the areas where the spray was more concentrated still left a film. I found this feeling was less noticeable when I straightened my hair but when curled you can feel that texture. I feel that the film almost acts like hairspray because I omit hairspray after I curl when using this product and the curls held up beautifully.

I haven't used this product while blowdrying but I imagine it would be a tangly mess.

After I spray this on, my hair feels really dry. Also, it makes my hair greasy within the day. I don't hate this product but it is definitely not one of my favourite.
