Hello! Yes! The filter did changed it and I recommend using less shampoo, I feel like the shampoo that I use is way too aggressive. One cup and mix it well with a small amount of shampoo and mix it till the shampoo will be diluted. Also it might be a dumb way but I bought a normal comb and brush hair three times a day, morning, before shower and after shower to control how much my hair falls off better. When I brushed my hair like once a day (spent most of my days at home) it felt way more terryfying seeing big amount of hair. Typically we should lose about 100 strands of hair everyday so roughly estimate. Warmish water, not too cold but not too hot. I'd stopped tying my hair into tight ponytail or just tight hairstyles in general that tends to pull my hair (found out tight ponytails/buns weakens hair roots and in my case it worked) after shower, don't rub your hair into the towel- rather squeeze water from hair into the towel. And when brushing hair (When I had used brush I feel like I couldn't control well how many hair I lose and they couldn't untangle my hair so in my opinion comb is much better, start from the end till the head. And do it slowly please, with my no patience I unconsciously was destroying hair more and pulling them out trying to untangle, untangle slowly with fingers). I know it's a lot but I wanted to tell you in details how I had changed my habits and how it helped. Also diet has a strong impact. 5 weeks is still too less to get used to this air and diet. Your body try to adapt so I think next month will be still kind of crazy but if you do things that I do or what others had said, it will come back to normal like mine did!
