i bought this product after developing a bit of frizz on my hair, most probably due to over-straightening. Usually i am wary of serum type products because i really dont want my hair to be looking too greasy so i approached this product with caution. However, it has to be said that this product really does work! if you hold it about 20cm away from hair and give a spritz then a very fine layer is transferred onto the hair which is just enough to tame any annoying fly-away hairs that one can get after straightening or blow drying. It really doesnt take a lot of spray to tame my frizz, i guess people with naturally very frizzy hair may want to try a stronger product but if you are looking for a slight gloss without greasiness then this is perfect! it really does just finish hair off nicely after styling and i like it so much ive added it to my repeat buy beauty products!
