Fantastic lather, silky hair!
I love this rosemary shampoo bar! I am amazed and impressed that the Rosemary Oil Shampoo Bar produces so much lather after just a few strokes of the bar on my wet hair. The lather made it easy to move suds over all my very long hair. When I rinsed my hair, I could tell it was clean because my hair "squeaked" through my fingers, which I prefer to having a greasy feeling that some natural shampoos leave. I worried perhaps the bar had stripped my hair of natural oils, but once my hair dried, it felt silky and not overly dry at all! When I used the shampoo bar for the first time, I also worried that the gentle rosemary scent of the lather would last after rinsing it out. But, to my happy surprise, after rinsing and letting my hair dry, no rosemary scent lingers. Instead, my dry hair simply smells clean and fresh. Best of all, the shampoo bar leaves my hair feeling very silky, soft, and sleek without any conditioner or natural detangler spray! (I am petting my hair right now. :) I loved the shampoo bar soap so much that I bought a bar for my son and one for my mom. My son just told me today that he ALSO loves the shampoo bar. He told me his hair has never looked as good before in his life as it does now! He was genuinely excited about the shampoo bar. When a young man is so happy with a shampoo bar, you know you have a good product. I am amazed that humanity was able to send people to the moon and *also* make this wonderful shampoo bar! It is awesome. I didn't know a month ago that shampoo bars even exist. I am so happy I stumbled upon them, and this bar, in particular!

Works Amazing!
I purchased this along with the shampoo bar and I am a convert. The shampoo lathers impressively and while the conditioner feels a bit different from liquid types while working it in, it really softens the feel of my hair without it feeling greasey. Both rinse out very easily. I've been using both for a week and the health of my hair is noticably different. For context I am an over 40, stressed out mom that has always been too busy to be bothered to do more than toss my hair in a ponytail tail. Over time though and with my active lifestyle in martial arts and outdoor work my hair has taken a toll. Nothing seemed to really help. Then I decided to give bar shampoo and conditioner a try with ingredients to help tame the breakage and abuse and after day one it was a big difference from using liquid shampoos. I noticed my hair broke less when being brushed and had a much nicer appearance. My scalp also stopped having the itchy feeling. After a week of use I went on a trip and ended up having to use liquid shampoo/conditioner again and instantly my hair was back to all the prior problems with itchy scalp, crazy shedding/breaking and general unmanageable feel. All glossiness was gone. I can't tell you how happy I was to come back home and get back to this shampoo and conditioner. It's really the best. Even my husband loves it and notices how it makes his scalp and hair feel healthier. The big test is now to see how long the bars lasts!

Great lather, gentle clean — feels good to ditch the plastic
I wasn’t sure how I’d feel switching from liquid shampoo to a bar, but this one made it easy. It lathers up way better than I expected and leaves my hair feeling clean without that dry, squeaky feeling. I’ve been using it for a few weeks now, and my scalp feels healthier — plus my hair seems a bit fuller at the roots. The ingredients are really nice too — you can tell it’s not just a “soap bar.” It smells fresh, like real rosemary, and the mix of oils keeps my hair soft without weighing it down. I also love that one bar lasts as long as multiple bottles and there’s no plastic waste. Only thing is, it can get a little mushy if you don’t keep it on a dry rack, but that’s an easy fix. Overall, it’s a great eco-friendly swap that actually works. The Bar itself is white color. I give it a 4 star, I would like to see the price lowered, organic soaps tend to wear down quicker than standard.

Love the Eucalyptus Scent!
This one is my favorite! I totally enjoy the eucalyptus scent everyday when I shampoo. Now I even ordered the same scent conditioner bar. My hair is doing well too.

Shampoo is just ok.
I love castor oil and use it daily. This shampoo is good, and my hair feels healthy. It does not present any new hair regrowth however. My hair is not any thicker than when I began using the shampoo. I have been using it since February. I would suggest buying a shampoo that has castor oil and rosemary in it. I will look in their products and check for other ingredients as well.

An amazing natural alternative to regular shampoo
OMG!! For my first time using an all natural bar shampoo, this was the luckiest pick I could make. I was a little skeptical because I was worried about smelling like rosemary, but the scent only lasts as you apply it and does not stay after your shower. It lathers beautifully and lasts a long time so you don’t have to keep purchasing so close together. I also want to mention that since I’ve started using this, my hair loss in the shower has decreased SIGNIFICANTLY!!! I used to basically pull chunks out while using L’Oréal, and ever since using this I haven’t had that problem. My hair does feel drier, so I’d say it’s definitely not going to make your hair silky or anything but you will have a thicker head of hair and feel good about the ingredients in this! Would recommend and will keep buying!

The lather is insane!! With an amazing price?? I must be in heaven.
So I just received this a few hours ago and I was so excited to use it. I first shampooed normally and then used this after. Once I got out of the shower, I use a leave in conditioner. For reference, I have curly hair, it could get as lose as a 3A & as tight as a 3C. Usually though my hair settled is a 3B. I’m starting my hair growth journey, and I thought this would be good for me. The only reason why I purchased this is because it was the best bang for my buck. And I thought “you know what I don’t really care if it has any reviews, the brand looks professional and promising enough.” I have always been interested in purchasing a hair bar for a while. My only concern was that it was going to be difficult to lather, my expectation was for it to be as good as a body bar. Let me tell you right now. You do not have to worry about the lather with this product. I already noticed that lathering in my hand that it was very effective, so I put it directly on my scalp as shown in the video. Oh my God. it’s crazy. Honestly, I think I would’ve been fine with the first swipe. Doing it three times was overboard. In the video I lather my hair for 11 seconds. YES - SECONDS. My first swipe was only 3. That’s enough evidence for me, in my opinion. The more I kept on lathering it in my hair, the more luscious it got. Gosh I wish I could add more videos because my reaction is priceless!! Also I got a $2 off coupon when I purchased this, not exactly sure for what… but you bet I accepted it!!! It amazing and heavenly. I usually shower in boiling hot water and it lasted fine. I do end my shower and ice cold water and again it was fine. It doesn’t have that traditional slimy soap feel, but it is kinda similar. Not slimy, but like gooey. ? Not exactly sure how to describe it, but it’s not as bad as the slime. I think I might store this in a container to make sure it dries well but I don’t think it would be awful if I just left it out. The size is really good as well. The length of my hand is almost 6 inches and this fits in my whole palm. (Also if you like making soapy videos for you significant other, then I don’t think you’ll be disappointed since there is soooo much lather. I really like the way this looks. If you know what I meaaaannn.) I may be a dramatic writer, but it feels right to say this. I love this product and I will definitely be doing a month check in. Written : September 8th, 2023.
