Overview
Washing with this Peter Thomas Roth shampoo cleanses while pro vitamin B conditions the hair without weight. It aims to strengthen strands against breakage and add body and shine.
Conditioning without heaviness suits hair that goes limp under rich formulas. With no size, hair type or sulfate information, it is hard to judge against other shampoos.
Who it's for
Hair that snaps when brushed and looks flat can benefit from the strengthening and body claims. Those with specific ingredient needs will find too little detail here.
Pros and cons
- Helps reduce breakage
- Size not listed
- Sulfate content unknown
- Hair type not stated
Performance notes
Panthenol absorbs into the hair and attracts moisture, which makes strands more flexible and less likely to snap. Because it is light, it conditions without flattening roots, which is where the body comes from.
