Your Hair Isn’t the Problem. Your Shampoo Is.
Sulfates, silicones, and single-use plastic. Your shampoo was never built for you, or the planet.
Get 32% OffYou read labels. Your shampoo counts on you not to.
Sulfates strip your scalp of the natural oils it needs, leaving hair dry and brittle over time.
Synthetic buildup from silicones and fillers clogs the scalp, quietly weighing hair down.
The damage is slow. That’s why nobody talks about it.
It doesn’t happen overnight. It happens wash after wash. Invisible, cumulative damage that adds up long before you notice it in the mirror.
What the ocean figured out first.
Mar is built on Keramere™, a vegan keratin derived from marine brown algae and kelp, alongside Fucus Extract and Laminaria Extract.
Your bottle shouldn’t outlive your hair.
Conventional plastic bottles can take hundreds of years to break down and are rarely recycled, so most of them end up sitting in landfills and oceans long after what’s inside them is gone. Mar bottles are made from infinitely recyclable aluminum instead, and every Duo order removes 2 lbs of ocean plastic through our partnership with Plastic Bank.
