Noticeable Softness!

I tried this at a hotel and fell in love with how worked on my dry hair. I have gone through chemo and didn’t lose my hair but the texture changed and this shampoo makes my hair much softer. The conditioner is great, too!

I would skip

If there was one word I can describe this shampoo with, the word harsh is what comes to mind. Definitely not for me. May work for younger men with oily hair? Nope, do not recommend, especially if you have colored hair.

Better for oily hair

I have long, dry hair. This is a clear shampoo which usually means it's not going to be as moisturizing as I prefer. I like that it makes my roots less oily for a couple of days, but not worth how dry it makes my ends.

My go to shampoo

My go-to shampoo I have religiously used this shampoo for years. One bottle will usually last me about a year or 1.5 years, so for the price range it's a steal. It's the only one that cleans my hair and gives me volume that lasts without weighing it down or making my strands oily within a day. I have chin-length very fine hair so anything makes it look flat. I see a noticeable difference in volume when I wash with my PTR shampoo vs. when I wash with something else. And this includes fancy stuff like Olaplex -- would make my hair feel great, but give me no root volume. I owe it to Marriott for introducing me to these shampoos. If you ever stay at a hotel that provides the minis - grab them!

Drying

I really love PTR so I wanted to love this too BUT it leaves your hair feeling STRIPPED after you wash it and that is NOT what a "Mega Rich" shampoo should be doing. I need moisture added and if it feels dry while shampooing then that's a problem.
