- Jennifer Q.Verified BuyerReviewingRosemary Shampoo | Multi-Protein | TravelI recommend this productWhat are your skin concerns? Eczema/Psoriasis, IngrownsWhat are your hair concerns? FrizzRated 5 out of 5 stars6/24/26Exceeded Expectations
I discovered Necessaire while doing research for healthy products, and I don't want to ever go back! When I read "Rosemary" in the description for this shampoo, I thought this would be a hit or miss. My brain just thought of it as a food spice and kept it in that lane. Well, my brain was very wrong and it is 100% a hit! It smells so good, cleans my hair, keeps it soft, is weightless, is packaged like a luxury product, and overall might be the best shampoo I've ever used. Kudos to whatever genius designed the twist cap, it is a game changer for not leaving hardened globs of product or clogging. This shampoo also does not seem to be bothering my hand eczema in any way after weeks of use. If you're still cautious about the scent, just try the mini bottle set like I did and see for yourself. Happy testing!
