History of my hair, and my current hair care routine

  The year was 2011, I lived in the United Kingdom, my hair was bleached blonde, dry from the everyday straightening and barely hanging onto my scalp. I am a dark brunette naturally, my hair is very wavy and frizzy, and I've been struggling to make it look presentable, for my whole life. I've tried many hair products while living in UK. I moved a few times while living there, but I always ran into the same problem - I had the hardest time washing shampoo out of my hair. Fun fact: Did you know that the same product for example a shampoo might have the exact same packaging but a slightly different amounts of ingredients depending on where it is sold? Companies that make the product take into account the hardness of the water in the country where it is sold.
When I lived in Lithuania, I knew that the water there was hard. It did a good job of washing out excess of moisture, or product out of my hair. The first thing that I noticed after moving was, that tap water in  the UK was very soft. That is supposed to be good for your hair, since hard water contains more minerals that can damage your hair or whatever... The water in UK is hard, but I'm gonna assume that every house I lived in, had a water filter. Still, the hair products in the UK are made for hard water (I am assuming). Nothing worked for my hair... I've tried many hair products, my hair was dry, damaged and horrible, the only products that helped a little were Aussie 3 minute Miracle deep conditioner and Moroccan Oil.
The minute I moved back to Lithuania my hair became way better, I went back to my old favorite products, stopped bleaching as much and I grew it out quite a bit.
3 years later some genius installed a water filter in my house. Coincidentally I have started bleaching my hair again. I've had a bit of a hair disaster (one of many in my life). My hair started to fall out, my favorite shampoo was irritating my scalp, when I washed it, my hair was very dry and no product helped to moisturize it. I was loosing a lot of hair too...

How I saved my hair.

1. I have stopped bleaching it. You'd be surprised how long a blonde can rock the outgrown roots (now I only add a few highlights a few times a year, and pretend that my hair is a stylish ombre balayage).
2. I started investing into some better and more expensive hair care products.
3. I have stopped washing my hair from 3 to 4 times a week to 2. My hair doesn't get as greasy now.
4. I try to put less heat on it, straightening only 2-4 times a month and blow drying only when I wash it before sleep.
5. I don't sleep with my hair wet. I always braid it before sleep.
6. Hair oil. I found a good hair oil that I apply after every wash and sometimes once in between washes if I feel that my hair is getting dry.
7.I try not to brush it wet. I have noticed that if I wait until my hair completely dries and applying some hair oil after, instead brushing it wet I loose way less hair.
8. Brushing the ends of hair first and with small strokes moving up  until I reach the roots. I have never had hair this long and I've read in some article online, that long hair requires more delicate and careful brushing.
9. Praying for the Hair Gods every night before sleep.
10. Trying not to worry as much. It is inevitable that my hair quality will decrease with age. The worst case scenario, I can wear a wig:

As for the products that I use, there's only four:

Best cheap hair mask I have found in drugstore + Aussie Shampoo + Aussie Oil and sometimes I steal a tiny bit of my mom's  hairspray to keep down the flyaway hair.
