I have fairly long hair and after having it all dyed blonde for 2 years, i decided to go back brown as the bleach had left it extremly dull, tired and brittle. I started off with expensive shampoo's and conditioner's thinking if i spent more it would do a better job, which wasnt the case at all. Last resort before i got it all chopped off, i tried Herbal Essence's strenghtening shamppo and conditioner. I was dubeous at first, but my hair became soft, shiny and manageable straight away. I found it stopped my hair breaking and becoming frizzy, and soon after a few washes using the product, it became managable all the time. I cant belive how quickly it has worked esp considering what a state my hair was before from all the bleach. I shall definatly never leave herbal essence's now as it does exactly what is says and is very affordable
