I’ve emailed their support to ask them about that skin reaction, it may just be your skin type as I don’t notice anyone else online mentioning that. Glad to hear it helped the wrinkles on your forehead, would you have before/after pictures if you don’t mind sharing?
That’s some good advice from the other first commenter. I also do scalp massage and use that soap which has helped me. But taking a good supplement is also important and i’m not sure about viviscal, as I haven’t tried it, but by looking at the ingredients I think you are better off buying from a known company that provides good supplements.
Reason for that is, it’s easy to add cheaper quality supplements to boost profit margins for these companies. And often the more expensive supplement you buy (in its plain form like Biotin alone), the more expensive, the better.
