Hi I have posted about thinning hair recently and I have done a lot of reading on the subject.
By chance I came across a thread on mumsnet about greasy hair where someone mentioned dry shampoo as a possible solution, and then another mumsnetter said "Beware of dry shampoo, it thinned my hair a lot".
That sentence stuck to my mind, because I have been using the dry shampoo Baptiste (probably in excess) for the past few years.
When I say in excess, I mean every single day (expect on the day of washing my hair and the day after), but then I would only wash my hair once a week or less
thinking that it would be much better for the health of my hair.
I heard so many times that washing your hair often was bad for it, but now I'm wondering if a dry shampoo could have done some harm instead.
My hair has less volume than it used to have, but is definately showing signs of thinning more on the areas where I used to spray the dry shampoo. 
I read somewhere on the internet that dry shampoo soaks up the grease and gathers it to your scalp and it then clogs the pores which makes regrowth difficult.
I was wondering if anyone had experienced a thinning of the hair after using dry shampoo excessively?
P.S: I did do all the blood tests and they came back normal.
