This is by far the best hair serum I've ever used. I have long, thick and dry hair, which has a lot of frizz if I don't dry it properly, and all major brands don't work (John Frieda's Frizz Ease is overrated IMHO). This Silkening Serum is a very light cream with lots of cones (similar in consistency to serum that you would use on your face!). I usually apply just before blow-drying and it leaves my hair really smooth and sleek. Sometimes I use to touch up when the weather is humid and I need to control the frizz. It's also super moisturizing (I sometimes squirt too much and use the remainder on my hands - it's non-sticky, absorbs well and leaves my hands really soft!). Anyway - I think it costed about £3, but I got it on promotion and can't remember the original price. There's loads of product - much more than usual smoothing serums. This is HG for my hair - I hope they won't discontinue this.
