TRESemme Shampoo & Conditioner causes Alopecia

In 2008 me and my wife used Tresemme Shampoo and conditioner which was purchased at the local supermarket store in the UK and after using the products first my wife woke up with smooth bald patches on her head in two place, they grew larger and larger as the days and weeks went by until they reached around almost 4 inches in diameter. She was shocked, distressed and distraught by this ordeal. There wasnt really anything we could do about it, after a visit to the local GP she tried steriod gel for the bald patches which didnt improve her hair loss.

Some weeks after i used the same shampoo and conditioner and woke up with the same situation that my wife woke up in but had around 3 patches the size of a 50p coin, after several days the patches starting getting bigger and spreading to different parts of my head, in total i had around 6 in different places.

Its been almost 8 months now and the patches have gone finally however in places the hair is still growing and becoming thicker.

We have contacted Tresemmme and complained about what happened to both of us and they basically fobbed us off and told us after a Full Labatory investigation the samples were in 'completely satisfactory condition'.

I wanted to ask if anyone else out there has used Tresemme Products and had alopecia?

Thank you
