Get it and try it it’s worth it
If you knew me and knew my hair issues you’d be shocked that I’m writing this because never in my 35 years has ANY shampoo, and I have tried sooooo many, made my hair feel this nice and soft. Actually I never even notice a difference between shampoos they never do much for my hair but man can I notice the difference with this shampoo, on my second use I didn’t have time to put any leave in conditioner after washing my hair like I normally do but even so my hair was so soft and nice I’m really shocked I have really unruly wavy frizzy hair and this shampoo bar has really helped I even feel like I’m not getting as much dandruff as I normally do between washes. I got the charcoal one and it doesn’t smell like anything but it has left my hair very soft, I’m a customer for life.

my new go to shampoo
I love this shampoo bar it is the first time I have used this type of shampoo I have always used shampoo in the bottles but decided to give the bar a try the first time I washed my hair with this shampoo I did not use conditioner I wanted to see if it was going to dry my hair out like some other shampoos have done in the past but this one does not dry my hair out at all in fact my hair was so soft that It actually felt as though I had used some conditioner it is easy to use the scent is light and and it lathers pretty well my hair felt nice and clean it was easy to use and rinse out I have sensitive skin and this shampoo did not irritate my skin at all I will be buying it again I think this is going to last me quite a while it may seem a bit expensive but to be fair this is going to last at least 2 shampoo bottles worth for me probably more I have bought some pretty expensive shampoos over the years and to be honest I like this one better

Ingenious shape
I’ve been using shampoo bars for the last few years and this is my absolute favorite. I appreciate so many things about it - subtle (and natural) scents even for me who is very sensitive, the shampoo works great for my wavy hair (great suds, non drying), and the shape is ingenious. Shampoo bars will always get to the point where they break on you because you’ve worn down an arch where the bar is in contact with your round head. But with the mars shape, the bar is the same roundness as your head so it doesn’t break and you have mush less waste.

Enhances hair AND eliminates plastic
I decided to try this bar shampoo after seeing other purple toning shampoo bars advertised on social media for twice the price. I know that castor oil is very good for skin, so I chose this brand. I could not be happier with it. My aging, graying hair is fine and curly, and it lacks body. This shampoo lathered beautifully and left my hair easy to comb with a wide-toothed comb after shampooing. I decided not to use conditioner as my hair and scalp felt so good after using this bar. I styled as usual (my hair frizzes with heat so I roll it wet and let it air dry). I very happy with my soft curls that display no frizz (even in the gray areas). I will be a loyal customer of this brand from now on. I am 77 and glad that I have eliminated another plastic container from my life.

Good shampoo bar, but I prefer the tea tree one
I really liked this shampoo bar — it lasts a long time and leaves my hair shiny. However, I personally feel the tea tree version works better for me, since it makes my hair feel even cleaner. Still, it’s a good product with solid quality.

Leaves hair soft, clean, and shiny
This shampoo bar worked better than I expected. It lathers really well, leaves my hair clean, soft, and lightweight, and it doesn’t dry out my scalp. The castor oil gives a nice shine and helps reduce breakage. I also love that it’s eco-friendly and lasts a long time. If you want a gentle, effective shampoo bar, this one is a great choice

Very excellent
I’m really impressed with this shampoo bar! It lathers up beautifully and leaves my hair feeling super clean, soft, and hydrated. I’ve noticed my hair looks shinier and feels stronger since I started using it. The scent is light and pleasant, not too strong, and I love that it’s made with natural ingredients. It also lasts a long time, which makes it a great value for the price. Overall, it’s an amazing eco-friendly alternative to liquid shampoo. I’ll definitely keep buying this one!

Just a regular shampoo bar - nothing special
Did nothing to calm my scalp of itchiness or dandruff. There was nothing special about the shampoo except that my hair felt clean. However, I purchased this with the hopes of it calming my irritated scalp and strengthening my hair so that it wouldn't fall off as much during washes but it did none of that. It's good for just simply washing your hair but there's so many shampoos (bar or liquid form) that do a better job. There's a slight scent to it but it doesn't really last in your hair either so this could be a good or bad thing depending on the person.

Excelente shampoo en barra, lleno precisamente un mes usándolo y deja el cabello genial. Es una gran opción si quieres dejar atrás el shampoo tradicional, además estoy usando el acondicionador y juntos hacen magia

ME ENCANTO!!!, recomendadisimo chicas y chicos. Es natural y llegó bastante rápido, en solo dos días. Se los recomiendo demasiado, tal vez huele no tan dulce o del agrado al llegar, pero una vez aplicado deja un olor entre dulce sin empalagar y un neutro, como arroz dulce. Por ahora me ha encantado, pediré el acondicionador
