Meet the founder
“Nothing worked for me, so I made it myself.”
Caden couldn't find a hair product that actually held up, so he and his brother built their own. That's still the bar for everything we make.

Why CS THEORY
Made for guys like us
Nothing on the market worked for us. So we made our own.

No fillers. No compromise.
We don't add ingredients to make the label look impressive. Everything in our products is there because it works.

Built for results
No crunch, no grease, no buildup. Just hair that actually looks good all day.

Made by guys who care
CS THEORY was built by two brothers who were tired of products that overpromised and underdelivered.
FAQ
Questions, answered
What ingredients do you leave out, and why?
No sulfates (SLS or SLES), no parabens, and no MCI/MI. Sulfates are harsh detergents that strip your scalp's natural oils and can leave it dry and irritated. MCI/MI are preservatives that are among the most common causes of skin allergies in personal care products. Parabens are preservatives a lot of people would rather avoid, and our formulas don't need them.
Are your products all-natural?
No, and on purpose. We use natural ingredients where they perform, and proven synthetics where they work better. We'd rather it work in your hair than look good on a label.
How do you choose your ingredients?
Every ingredient has to do a job: hold, texture, or keeping the formula stable. If it doesn't make the product work better, it doesn't go in.
Do you offer free shipping?
Yes, on all orders of $70 and up, in the US and internationally. Orders ship from our Texas warehouse in 1–3 business days.
What if something goes wrong with my order?
If it arrives damaged, it's the wrong item, or it never shows up, we'll send a replacement or refund you in full, with no return needed. Just email info@cstheory.co.
