Nose shed? Algae, and scales scratched?

[Reality]

So I was just wondering about my dragon and all of a sudden I thought....Nostrils. So I checked to see and I saw his left nostril has covered up by i'm guessing is shed. 1.) Wanted to know if this looks all fine and natural to you?
2.) The right nostril got me a bit worried its not as "open" as i thought, maybe the same thing is going to happen to it soon, just in progress? Please let me know your thoughts, thanks!

Now in my last post I had a HUGE problem with algae, which now is down to a minimum. Though he does have some in/around his "ear hole." 3.) Have any idea on how to take the remaining off without it hurting my dragon, or just wait for her to shed her skin? I've been using a toothbrush to gentle brush it off, but in the ear area i'm scared to get a string inside her ear and hurt her or damage something else.

Last thing I wanted to talk about is on top of his head, piece or pieces of her scales are grey-ish white. I thought it would be urates. Though when I tried to clean it off, it stayed. 4.) What could it be? Did she scrape the top of her scales off?
5.) If she used to have algae on her skin
, if shed comes to play will her new skin be some greenish color?
6.) Also the tip of her mouth on the top is some greenish color as you can see in picture #1 & 2. It looks like it is algae but does not come off, can it be algae but stuck for good until it sheds again maybe? Cant wait until she becomes pretty again! To treat her with love, and most of all be more careful and wary of what I do!

Awesome
Bonus!
How often would a 3-4 years old bearded dragon shed in a year? (For Ex: 3 to 4 months, etc)

I was just wondering about this guy the other day. Glad you got the algae off! I think at this point you might just have to wait for the next shed for the rest to come off but I would continue with the baths and gentle scrubbing. I don't really think that when he sheds the scales under are going to be green. The algae just covered the top scales. As for the white scales on top of his head, have they been there for awhile? It kinda just looks like stuck shed. You could try rubbing pure aloe on it at night when the lights go out to see if that loosens it.

As they get older they don't shed as often. Plus they only shed small parts of their bodies at a time. Right now my 3 year old is shedding one of her little shoulder pads and that's it!

I also was wondering how she was doing.. looking really good!! the rest will come off in the shed, sounds like your doing a great job! The greyish scales on the top are you talking about those white ones or is it the 1 in the middle her 3rd eye? if it's the white ones those should come off when she sheds her head if it's the 1 scale in the middle that will stay greyish...
yea the shedding slows down as they are older just bits and pieces here and there
