[Shasown]

ok the real reason, she went in with hair extensions in, she didnt take care of them properly, they eventually came out removing some hair with them, then her hair has still been growing, it hasnt been cut properly nor thinned down, so it will look patchy and badly cut at the moment.

Any further hair loss on her behalf may be caused by the stress of having a bad hair month or two (alopecia)

Or it could be her end of summer moult as I previously suggested.
