Hair care hair loss shampoo I bought with my own money

I purchased Beer Lab Beer Yeast Shampoo because I was experiencing severe hair loss. I wasn't even on a strict diet, but my hair kept falling out, which was very stressful. However, since using this shampoo, I definitely feel like I'm losing less hair. My hair had also become very thin, which was stressful, but I like that it is gradually getting thicker.

I thought the scent would be strange because it contains brewer's yeast, but the shampoo smells nice, so I keep using it.
