I have thick long hair that tends to be oily on my scalp and dry at the ends. I will use head and shoulders once a week to give my hair a good clean (i alternate between H&S and my regular shampoo and conditoner) i use to use selsun blue for dandruff but i hated the smell, H&S is much more pleasent and clears dandruff well.
It does tend to leave my hair quite dry though so i either use my regular conditioner after using H&S shampoo or i use a but of hair oil after washing my hair.
Over all i am happy with this product, it is a bit pricey but the big bottles are great!
I liked the idea of having a shampoo and conditioner in one - as I tend to be a bit lazy. However, I bought this to help with my dandruff.
I used this every time I washed my hair for just over a month. FirstLy I found the smell absolutely repulsive - it's a kind of gross sweet chemical smell. But because I didn't want to waste product I ignored it and used it anyway.
It didn't froth up a whole lot which I found a little odd, but it rinsed out well and my hair felt clean when I got out of the shower.
When I went to comb it, it was super, super knotty and it felt awful. It didn't feel sleek like it usually does after washing it. It was really painful combing my hair because it was so knotty.
When my hair dried it looked really dry and unhealthy. Initially I thought that this was just my hair adjusting to a new shampoo. When this didn't improve over the course of 6 weeks, I decided it was this - as I hadn't done anything different to my hair or diet.
Also my dandruff seemingly got worse. For the first two weeks it was really bad and my sister - who studied hairdressing, said that it is just the shampoo/conditioner getting rid of my dandruff. After this didn't improve I started questioning the shampoo but continued with it as I though it could just my scalp adjusting to it.
Alas, I loathe this shampoo/conditioner combo. It could just be my hair or my scalp not liking it - I'm not sure. My boyfriend swears by this and he has gorgeous shiny hair with no dandruff. But for me this was just awful. It didn't suit my hair or scalp. Based on this I will never buy or use this again, I've had better results using dishwasher liquid (the things you do when camping). I wouldn't recommend this based on my experience with it but my boyfriend has great results with it, so it obviously works for some - just not me.
