Hola Alberto:
I can see a difference in your beard, and it is getting darker. Since your beard is curly, you will not notice length, because it is filling in. That is why you would feel the density even before seeing it. You are looking great. As always, make sure to focus on the strengths. Your mustache, your chin and the area under your mouth are perfecto. Your underneath photo shows that both your right and your left side are coming out strong. Just keep up the good work, and enjoy the ice cream in your beard and all the little things that 18 month old hands can put in it. Enjoy the feeling yourself.
Tom
