To a certain extent I agree. It annoys me to see YouTube reviews where the person uses 10 products before they apply the product they are there to review. There's no way to determine if it worked.

For me, I went through a lot of products until I found what worked for me. Now I have about 10 products I will buy again, and that includes poos, conditioners, leave ins, oils, moisturizers and stylers. May sound like a lot, but I have about 30 to use up that I won't rebuy.
