Rather than strip the hair clean and then coat it (shampooing & conditioning), our goal is to try and keep your natural oils in balance. This means we don't distort your pH balance and natural oils like a shampoo would. Unlike shampoos, our products don't have harsh detergents that suds up and dry out your head and hair. Unlike conditioner, they don't leave hair limp and frizzy. Instead, they lightly clean your hair and scalp, cleansing hair while protecting its strength and texture. 

These don't need to be paired like shampoo & conditioner. You should only use one at a time, but many customers use both products on alternate days. When you're sweaty and need more of a clean, use the shampoo light bar. When you want more moisture and flow that day, use the mud.

Whether you use one or the other or both, it's all about finding the right routine for your own hair needs.

Yes, our products are free of parabens and sulfates (in fact, they barely make any suds at all...). The bar is free of plastic, silicone, and fragrance.

Our philosophy on choosing ingredients was to find the lightest, best performing ingredients to keep your hair and head in their natural balance. While we were initially skeptical of the scary names like 'alcohols,' we dug into it with more hair scientists. For some ingredients, we found that the strange names were the gentlest and best for your head, which is what matters most. And so you know, all the Modern Mammals employees use the product too, so trust that we will only ever make it the best that we can.

Ingredients for each product can be found on their product page.

Our bars have no plastic packaging, and their box is fully recyclable, made out of post-composite materials.

Our bottles are made of hdpe plastic, one of the most easily recyclable and sustainably used plastics.

Yes. The only animals involved in the making and testing of this product were a group of guys who volunteered to be our test subjects. It’s totally vegan.

We formulate, produce, and ship all in the USA

Obviously anyone is welcome to use the product. What we have found though is that men really love the product because it keeps a balance of their natural oils, which gives their hair a thick and moisturized feel, almost like a swim in the ocean. We’ve also found that guys are really drawn to our product's focus on scalp health, as well as our dedication to simplicity and convenience.

We have lots of female customers who love both products! We just would not want to give anyone a bad hair result.

If you're curious to try it, it makes your hair feel incredibly soft with a light bit of texture to it that gives it some weight and prevents flyaways.

We designed the brand for men because we felt like guys needed haircare products that spoke to them and their daily routines. Last but not least, it's not just about hair - guys need something they can be a part of in today's distributed world

We'd say no, but do what works for you. Our typical customer is using modern mammals most days per week with nothing else, but we have some users shampooing once a week still. It depends on a lot of factors, like hair length, how much you sweat, and if you use a lot of styling product. We are sure you know more about your hair than we do, and we think you should figure out what works best for you.
