Ok first of all, this is the worst post as we dont have a comparison. The other picture isnt clear nor is it showing the same part of your head.
However, I would say looking at the quality/density of your hair, it seems like your hair is thicker, which in itself looks like you are getting results 1.5 months in. If this is in fact the case, I think after 3 months, you should see even better results!
