Strange boa

[Caillaech]

I am new here and I have a strange boa question. I picked up a hypo red tail 2 years ago and she had a couple of weird white scales and in the period I’ve had her she has shed multiple times of course every time she sheds the white scales have spread and now she looks like she’s covered in snow flakes. They feel normal and nothing is wrong with her health wise it’s the first thing I checked. Nobody has been able to tell me anything and she doesn’t look like the snake I bought anymore
