When I saw that Necessaire released another product in their rosemary hair care line, I had to try it. I am SO glad I did because it exceeded my expectations! This leave-in mask completely retexturized my hair. My frizzy, crazy, dry hair dried smooth, tame, and wavy. Absolutely phenomenal product! Necessaire’s whole rosemary hair line has completely transformed my hair. Everyone has been noticing how much better my hair has been looking lately!
- Emily L.Verified ReviewerReviewingRosemary Leave-In MaskI recommend this productWhat are your skin concerns? Aging, DrynessWhat are your hair concerns? Dryness, ThinningRated 5 out of 5 stars1/24/26Can Rosemary Leave In Mask stand alone after shampoo or is it necessary to use both conditioner and leave in mask?
I generally just wash my hair a couple times a week. I don’t use products or a blow dryer. Would it be ok to shampoo then use leave in mask or is it essential to use both conditioner and the mask? Waiting to order after hearing feedback on this question. Thank you.
NNécessaire1/26/26Thank you for your question. The Rosemary Leave-In Mask is formulated to be versatile and can certainly be used on its own after shampooing. Since you prefer a simple routine and don't use heat styling, the leave-in mask should provide adequate conditioning and nourishment for your hair without needing a separate conditioner. Your low-maintenance approach to hair care aligns well with using just the leave-in mask after shampooing. You may learn more about usage on the individual product pages under the "Usage" section, following "See Usage". We appreciate you taking the time to share your hair routine with us.

I enjoy this product because it’s easy to incorporate into my existing routine, it really does make my hair feel easier to manage, and I like the simplified packaging compared to other leave-in products. You use this product after shampoo-ing and leave it in and style your hair as normal, so there’s no sitting around for an additional 10-30 min and there’s no additional step to your normal routine. The product itself is thick and creamy just like a conditioner. I was nervous it would make my hair feel like there was a residue to it after styling as normal OR even when air drying, but that hasn’t been the case. I really like using this product on the days when I use a clarifying shampoo. I was surprised at how much I appreciated this style of packaging for a hair mask. Typically, masks are given in a tub-style container because of the thickness of the product. This is obviously in a pump, but it’s a non-stick style of a spring pump like other Necessaire products. I’ve really enjoyed introducing this item into my hair journey and I’ll know in another 6 months if this is “effective” but I love it so far!

I was so excited to try this new leave in mask. I have been seeing great results from the rosemary serum, so I cant wait to see the long term effects of this one as well! I typically only wash my hair 1-2 times per week. I have long, thick and semi curly hair. I definitely have some heat damage from over the years and have been trying to minimize further damage and promote new growth. So far, the mask has been great. My hair feels healthier and shinier. The mask itself is not too thick or greasy. Much like the serum, the rosemary smell is not overwhelming at all. While it’s only been a few weeks, I would definitely recommend, especially if you use other products in the rosemary line. It’s a great addition to my weekly routine!!

I’ve been a huge fan of Necessaire’s rosemary products and the leave-in mask did not disappoint! I like how the scent is very natural and the hair mask is pretty light weight. I also noticed my hair looks shinier and less dry after using! Perfect with pairing it with their rosemary shampoo + conditioner and their rosemary hair serum.
