Amos Shampoo

Amos Shampoo, widely used in hair salons and needs no introduction!
The shampoo itself is good, as expected from its reputation (?), but since it is on the expensive side compared to other shampoos on the market that offer good value for money, I am using it very, very sparingly.
I also stock up in bulk when they come up cheap.
It smells nice, and knowing that many hair salons use it makes me feel even better for some reason haha. I have two types of Amos shampoos, and I use them interchangeably.
