I purchased the vaata hydrating shampoo and conditioner, and I noticed my hair was soft and more manageable on first use I used it a few times however I had some bad news now I'm not sure if it is the shampoo or stress related, each time I use the shampoo alone and nothing else I come out with so many spots in my head and it's never happened before, it's only when I use the shampoo it's quite itchy spots it does happen if I use wrong shampoo and conditioner, I don't want to say it's this because people have had good results but just incase it is this can you recommend me what to do please. I'm going to take a allergy tablet so the spots go away, once they go away I will try that shampoo again after some time and test it if it is the shampoo or not. I spend £18 which is a lot of money for a small shampoo and conditioner please can you guide Thank you
