Haircare engineered by
your own DNA.
Stop the trial and error. We analyze the genetic biomarkers in a single hair strand to formulate a perfectly balanced routine just for you.
Surface-Level Assessment
Take the standard industry quiz to see where traditional haircare stops.
What is your natural hair pattern?
How would you describe your hair texture?
How does your scalp usually feel?
What is your primary hair goal?
Analyzing Profile...
Cross-referencing traits...
Incomplete Picture.
A standard quiz only scratches the surface. Based on your answers, there are over 1,400 generic formulas that might work—or might cause damage.
Don't guess. Let your DNA dictate the exact chemistry you need.
Three steps to certainty.
A seamless at-home experience designed to unlock your hair's full potential.
1. Order the Kit
Receive our secure, medical-grade collection kit with clear instructions on how to harvest a viable strand.
2. Send Your Strand
Mail your sample back in the prepaid envelope. Our CLIA-certified lab extracts and sequences the keratin DNA.
3. Get Your Routine
Access your genetic hair profile online and receive your custom-formulated products delivered to your door.
We look beneath the surface.
Generic categories like "dry" or "oily" are symptoms, not causes. By analyzing your hair at the genetic level, we map over 30 distinct structural biomarkers.
-
Keratin Structure Mapping
Determines the exact tensile strength and elasticity of your hair to prevent breakage.
-
True Porosity Analysis
Measures exactly how your cuticles absorb and retain moisture, dictating your ideal oil-to-water hydration ratio.
-
Follicle Genetic Predisposition
Identifies potential future thinning or textural shifts before they happen, allowing for preventative care.
Your Custom Routine
A look at a standard 3-step regimen prescribed after your DNA analysis is complete. Every bottle is mixed to order.
Base Cleanser
$32A sulfate-free formula calibrated to your scalp's pH level, cleansing without stripping essential lipids.
Restorative Conditioner
$34Packed with amino acids matching your specific keratin profile to repair micro-tears in the hair cuticle.
Active Serum
$45A high-concentration leave-in treatment targeting your exact structural vulnerabilities for daily defense.
Proof in the DNA
Thousands have stopped guessing. Read how personalized chemistry changed their hair.
"I've spent hundreds on luxury brands that left my hair flat. Hair Theory discovered I have a rare low-porosity profile. The custom serum they sent completely changed my texture in two weeks."
"The science makes sense. Why use the same shampoo as someone with entirely different genetics? My custom formula feels incredibly premium and my scalp irritation is totally gone."
"The unboxing experience was beautiful, but the results are what kept me. It feels like having a personal cosmetic chemist. Best virtual enterprise concept I've seen."
Frequently Asked Questions
What exactly do you do with my DNA data?
Your privacy is our highest priority. We only analyze specific biomarkers related to hair structure and scalp health. Your sample is destroyed immediately after sequencing, and your data is heavily encrypted and never sold.
How long does the whole process take?
After you mail your strand, it takes about 5-7 business days for our lab to sequence and analyze it. Your custom-formulated products will then be mixed and shipped, arriving within another 3-5 days.
What if my hair is dyed or chemically treated?
Our sequencing looks at the root bulb and internal cortex structure, which remains genetically consistent regardless of external treatments. In fact, knowing your genetic baseline helps us formulate products to better protect chemically treated hair.
