Hair condition help please

Illness and other physical trauma causes hair and skin to be unhealthy because the body neglects it to put extra nutrients into healing.  (stress does the same thing)  Vitamins may help.  Your hair being heavily highlighted makes things worse.  Also, it sounds like you may have overdone the products.  You may try doing a stripping wash to remove build-up, then do a deep conditioning treatment.

I've only used the nexxus emergencee about 3 times in  about 4 or 5 months so not too often. I've not tried the nioxin and I would like too...only trouble is that I live in the UK and would probably need to buy from the USA, this sometimes incurs duty charges which can be quite expensive....and always at the back of my mind is the fear that once again... I will buy another expensive product that won't work for me and I can't really afford to do that...If I was sure that it was gonna work I wouldn't hesitate to buy it but there's unfortunetly no way to be sure. Tell me Julesyjul88....doe's this product make your hair feel supple and soft again too? Mine hair's  kinda like cardboard at the moment and I'm desperate to get it back into condition. Thanks in advance.

I've tried infusium leave in conditioner before but not the shampoo. It was ok I guess but not as good on my hair as I would have liked. However, Since the original posting,  I have not used any straighteners or heat at all on my hair and have been conditioning my hair everyday but only shampooing every alternative day and Its beginning to improve I think. I also think that I had quite a build up of product on my hair which was just making it worse so I used a clarifying shampoo to begin with which made a difference immediately. I also think that over-use of GHD's have been causing breakage and frying the ends of the hair, and this why the hair appears to  be thinning a little and feels rough to the touch. Today it's feeling pretty good and much more  like it used to be... which is a relief. I'll look into getting it trimmed I think and  continue with the softly-softly approach until it hopefully returns to normal. Thanks so much for taking the time to help out though....much appreciated.

GHD hair straighteners. These are professional hair straighteners and get extremely hot but they are the Rolls Royce of hair straighteners....only problem is that if your hair is a little fragile then these will really cause a fast deterioration in it's condition.  Thanks once again for your advice... my hair is looking and feeling much better now.
