K-Pak Smoothing Balm 200ml : 1 results priced between £10.00 and £25.00

I've definitely noticed less breakage when using this, however you only need a very small (5p size) amount or it can leave hair feeling a little tacky. But as a thermal-protector, strengthening and straightening(!) this is a pretty good buy. I also highly recommend Kerastase Ciment Thermique as a slightly superior product.
