I am still losing a lot of hair despite using the Phyto-Caffeine Tonic regularly. Are there some cases in which the product doesn't work?
The efficacy of all products depends on the metabolism of the individual. This is because each individual reacts differently. Some effects are also not perceived immediately, e.g. severe hair loss may be reduced but may still be slightly higher than normal. But you should use the tonic for a sufficient period of time before you make a final judgment. As a rule, you can expect to see noticeable results after about four months.
