Your shower is causing your hair fall
It’s a shower, you clean yourself and let’s be honest you should be doing it everyday if not twice if you’re a little obsessive.
Clean up your bathroom!
Go get all the bottles now and start by putting in the bin the ones you have actually finished, the ones that are almost empty put in the bin! Before you buy anything else this all needs to be used up or given away. The shampoo and co dictionary your using now is not the same as it was 2 years ago.
Once your done and finished with all these bottles or found a home for them, then it’s time to get into the salon and plan your hair care regime with intention. But until you make the effort in the bathroom nothing will follow suit.
