My favorite shampoo is expensive, so I was looking for a cheap shampoo to use as a backup, and I bought this shampoo that a YouTuber recommended. I had never had a good experience with a shampoo that wasn't sold at a beauty salon, so I didn't have high expectations, but it was 100 times better than I expected, and I'm excited to have found a shampoo that I want to buy again after a long time! By the way, my hair is thick, voluminous, easily dries and hardens, and is medium to thick in thickness.
