What we test for and why
Your genetic makeup and hormones play a key role in your hair loss and how your body responds to hair loss treatments. We analyze 15,000+ genetic variants to cut the guesswork and match you with the therapies your body will respond to.
-
MUC1Mucin 1
This gene is related to magnesium absorption. Variants could indicate if magnesium supplementation might benefit your hair health.
-
DMGDHDimethylglycine Dehydrogenase
This gene affects your body’s selenium levels. Low selenium can impact hair health, so variants here might suggest the need for supplementation.
-
SULT1A1Sulfotransferase 1A1
This gene affects how well you activate minoxidil. Variants may suggest the need for a higher dose or additives like tretinoin.
-
SRD5A1 & SRD5A2Steroid 5-Alpha-Reductase
These genes influence DHT levels, which affect hair loss risk. High activity may increase risk, suggesting DHT-blocking treatments like finasteride, dutasteride, or spironolactone.
-
MTHFRMethylenetetrahydrofolate Reductase
This gene influences your body’s folate levels, which are essential for healthy cell growth, including hair follicles. Variants may impact your need for folate supplements.
-
GPR44-1 & GPR44-2Prostaglandin D2 Receptor
These genes reveal your sensitivity to prostaglandin D2, linked to hair loss. Cetirizine may help by blocking this pathway.
-
COL1A1
Collagen Type 1 Alpha 1
This gene influences collagen production, affecting hair strength and whether supplements may be beneficial.

Your Questions, Answered
Here are some questions we usually get about Roots by GA. If you would like yours answered, please contact us.
What is the Roots by GA prescription topical?
It’s a dermatologist-backed, compounded prescription treatment that targets the root causes of hair thinning using medical-grade ingredients. Applied topically, it minimizes systemic side effects and promotes regrowth.
We also offer direct-purchase formulas so customers can start treatment without waiting for DNA results. If you take the Roots DNA Test later, we can personalize your formula even more.
