Hello, Martin.

Thank you for your question.

First, the doctor needs to see the condition of your scalp and hair. If you cannot visit our clinic, please send us some pictures for doctor`s examination.

Answering to your question, usually in case of hair loss using only shampoo is not enough. It should be the combination of internal and external medicine. Depending of your condition treatment period may vary. 

======================================
Can I see the effect (reducing of hair loss) if I use only the shampoo?
