Hey man if you like Cetaphil, you HAVE to try
Sebamed!!
I've been using cetaphil for years and never found a huge problem. My wife bought this Sebamed kit from Costco half a year ago, let me tell you, it feels completely different (in a good way)
I started doing a little research and here's a little summary about Sebamed...
Our skin/scalp has a natural protective layer called acid mantle, which is a little acidic (pH 5.5). most shampoo/wash/lotion out there have a much higher pH (yes, Cetaphil included, as mild as it seems) , so when you use products with the wrong pH, it strips away this layer and makes your skin/scalp dry, and then very oily to make up for the dryness

Sebamed was originally for people with sensitive skin, so their wash/shampoo/lotion are all pH 5.5, keeps your skin and scalp healthy.
Not irritating at all. After I use the shampoo, I never feel that tightness and dryness on my scalp. I also use their face and body wash, which is great because I get lazy, but this wash is good for both face and body.
