Unfortunately disappointed .... and allergic reactions

Hello There,
What I get is already gray temples with my 52 and I like I have worried this special shampoo my hair darker carrying. I used it three months and now canceled my subscription to and disposed of my remainders.
I have previously used Alpecin C + (the caffeine) and was very pleased with the shampoo. Now the tuning on the market, because I thought it's worth a try.
Conclusion after 3 months:

per: my hair felt while using strong at

Cons:
- After 2 weeks of use I noticed a tentative pattern baldness, which I have never been able to observe with me.
- My hair has turned darker not
- I've got small pimples on the head up to the neck - even though I'm allergic to anything really
- When applying, I felt a slight burning sensation on the scalp, pushing this on the effect of caffeine

So I go back to my Alpecin caffeine without Tuning
