On my face some part the beard is not coming and also on my mushtaches before i have it and also it is itching like something eats my hair

If your beard used to come in thick and it's now bald in patches, and you're feeling discomfort, than you really should see your doctor. There could be something medically wrong that's causing this.

I have been picking at my beard for almost 2 years. I went 4 days without touching it. When you touch your beard before growing for at least 30 days. I'm trying to grow one in 2-3 months to the bottom of my neck, 6 months to my stomach, then to the floor. I would try to keep everything away from your beard for 30 days. Using chemicals when it is so short is just another way of not growing a beard. I would also recommend all foods good for your beard. Almost everything I eat and drink is good for my beard. I had a longer beard 3 years ago.

When your hands have soap on them it stops your beard from growing. I try not even to have a blanket touch it cause of detergent on it.
