AI curl coach for natural, curly and coily hair
Coileen learns your hair — porosity, elasticity, damage and goals — and gives you a plan built for it. So you can stop guessing, stop wasting money on the wrong bottles, and start liking your own hair again.
The problem
You’ve done the research. You’ve bought the bottles. And your hair still does something different every wash day.
Every product the reviews raved about. Most of them were made for hair that isn’t yours.
Steps that worked for a different curl pattern, a different porosity and a different set of goals.
Twenty different opinions on oil, water and wash day — and none of them about your hair.
None of this means you’re doing it wrong. It means nobody has looked at your hair yet.
The shift
Porosity is a starting point, not a rulebook. Elasticity, damage and your routine as a whole matter just as much. A heavy oil can build up until even the right product never gets a chance to work.
When your plan fits your hair, you stop switching. And staying consistent is what lets your hair show you what works.

Real women, real hair
Coileen is built on the method behind Double Beauty’s 30-Day Hair Growth Challenge, shaped together with a community of natural-hair women.
From Double Beauty’s 30-Day Hair Growth Challenge, the method Coileen is built on. Shared word for word.
“At first i was a little skeptical about the 30day growth kit, cause it has taken me years to find out what was really good for my hair. My hair was not growing after a certain length and i convinced myself it was because i have low perosity hair. I think I tried every product in the stores some of them good and some of them i wish i never tried. …”
“I've been relaxing, straightning and bleaching my hair for years. A couple years ago I decided to go natural. In the beginning of this year I just had a couple inches of straight hair to go. When lockdown came, I decided to cut these strands off. It left my hair without any shape, but it was so healthy looking. …”
“Wow! For the little amount of work to complete this challenge I am truly astonished by the results. Just 30 days and a new regimen can change soooo much!!! Thank you Double Beauty for this great idea and see you in the next challenge. ❤️”

Why we exist
We’re Chanaz and Chanyn, twin sisters and the founders of Double Beauty. For years we trusted products made “for our hair”, and our hair just got drier. Learning to read the label changed everything, so we started sharing what we learned with our community.
Then something stopped sitting right with us. Many of the companies selling curl products to natural women still sell relaxers, which research has linked to cancer.1 And the brands that dominate the shelf are owned by a handful of global groups and private-equity houses. You deserve advice that’s about your hair, not about what’s on the shelf.

To help every woman understand her hair well enough that she doesn’t have to keep guessing.
Coileen doesn’t sell hair products. Every answer is about your hair, not a bottle to push.
Options and tradeoffs in plain words. You decide what goes on your hair.
Shaped by the women in our Facebook group and the method behind our 30-Day Hair Growth Challenge.
