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 20 genes that help us get a better understanding of your optimal treatment.

  • CYP19A1

    Aromatase

    Regulates testosterone-to-estrogen conversion, influencing DHT levels and hair loss prevention.

  • SULT1A1

    Sulfotransferase 1A1

    Determines how well your body activates Minoxidil, a key ingredient for hair growth.

  • SRD5A1

    Steroid 5-Alpha-Reductase

    Affects DHT production, a major contributor to hair loss.

  • SLC23A1

    Vitamin C Transporter

    Controls vitamin C absorption, essential for strong and healthy hair.

  • ZPR1

    Zinc Finger Protein

    Regulates zinc levels critical for hair health.

  • MUC1

    Mucin 1

    Indicates magnesium absorption's effect on hair strength.

  • DMGDH

    Dimethylglycine Dehydrogenase

    Impacts selenium levels vital for hair health.

  • NQO1

    NAD(P)H Quinone Dehydrogenase 1

    Supports antioxidant defenses to combat oxidative stress-induced hair loss.

  • CRABP2

    Cellular Retinoic Acid Binding Protein 2)

    Influences vitamin A metabolism for a healthy scalp and hair.

  • BTD

    Biotinidase

    Ensures efficient use of biotin for hair growth.

  • ACE

    Angiotensin-Converting Enzyme

    Enhances blood flow for better hair growth via circulation-boosting treatments.

  • PTGES2

    Prostaglandin E Synthase 2

    Optimizes response to prostaglandin-based hair growth treatments like Minoxidil.

  • COL1A1

    Collagen Type 1 Alpha 1

    Supports collagen production to strengthen hair structure.

  • MTHFR

    Methylenetetrahydrofolate Reductase

    Affects folate levels, promoting healthy hair follicle growth.

  • PTGDR2

    Prostaglandin D2 Receptor

    Manages sensitivity to prostaglandin D2, a compound linked to hair loss.

Ingredients for growth

Our custom treatments combine proven prescription hair loss treatments and other effective clinically validated ingredients to achieve the best results.

  • Dutasteride

    Inhibits the production of the Dihydrotestosterone (DHT) hormone that causes hair loss.

  • Latanoprost

    Has been found to help with hair loss by extending the anagen (growth) phase of the hair cycle. It is a prostaglandin analog that promotes hair growth by increasing the density, thickness, and pigmentation of hair follicles.

  • Finasteride

    Helps treat hair loss by inhibiting the conversion of testosterone to dihydrotestosterone (DHT). By lowering DHT levels in the scalp, finasteride slows hair loss, promotes hair regrowth, and helps maintain existing hair in individuals with male pattern baldness

  • Melatonin

    Studies suggest that melatonin may help reduce hair loss and promote regrowth by extending the hair growth phase, reducing oxidative stress, modulating immune responses, and improving scalp health.

  • Caffeine

    Caffeine can stimulate the scalp through blood flow, supporting hair follicle health — specifically, the anagen phase of the hair growth cycle.

  • Spironolactone

    Slows androgen production, decreasing testosterone. May act as combined or solo therapy for androgenic alopecia.

  • Tretinoin

    Promotes and regulates skin cell development. This creates a favorable environment for hair growth. Thought to work synergistically with minoxidil. May penetrate hair follicle better when in combination.

  • Vitamin D

    Vitamin D may support hair health by promoting hair follicle function, reducing inflammation, and regulating the immune system, which can help prevent hair loss and encourage regrowth.

  • Cetirizine

    Motivated by the success of hair growth in other prostaglandin pathway medications, researchers studied the use of topical cetirizine in patients with androgenic alopecia and found that it may increase hair density and hair diameter. 

  • Minoxidil

    Helps with hair loss by stimulating hair follicles and increasing blood flow to the scalp, which promotes hair growth. It is a vasodilator, meaning it widens blood vessels, improving blood circulation to the hair follicles.

Frequently asked questions about hair loss treatment

We analyze 7 biomarkers and 16 genes known to affect hair loss and growth.

Why does a genetic test matter for hair loss?

Roots by GA addresses a wide range of hair loss concerns, from early-stage thinning to more progressed balding, including male pattern baldness, androgenic alopecia, alopecia areata, shedding, diffuse thinning, patchy hair loss, widening part, and general hair fall. Our customized topical solutions are tailored to meet your specific needs—whether you’re aiming to stop hair loss, encourage regrowth, or enhance hair density.

What types of hair loss can be helped?

Roots by GA addresses a wide range of hair loss concerns, from early-stage thinning to more progressed balding, including male pattern baldness, androgenic alopecia, alopecia areata, shedding, diffuse thinning, patchy hair loss, widening part, and general hair fall. Our customized topical solutions are tailored to meet your specific needs—whether you’re aiming to stop hair loss, encourage regrowth, or enhance hair density.

What ingredients are in Roots by GA's formulas?

Roots by GA uses a comprehensive range of FDA-approved topical ingredients, such as minoxidil, which can be prescribed in varying dosages tailored to your unique genetic variations and enzyme activity. Additionally, we incorporate FDA off-label medications like finasteride and its stronger form, dutasteride, to help reduce DHT, a hormone that can contribute to hair loss. DHT levels vary among individuals based on genetic factors, and addressing this can be critical in slowing or reversing hair loss.
For those less responsive to minoxidil, or for a more multitargeted approach, ingredients like latanoprost and cetirizine are available to support hair regrowth. Spironolactone, often recommended for women, helps reduce testosterone levels, which can also contribute to hair thinning. To further enhance treatment, circulation modulators like caffeine are used to promote blood flow, especially in cases where genetic markers suggest it could be beneficial. Other clinically validated ingredients include tretinoin to improve absorption, as well as vitamins and hormones like melatonin, which contribute to overall scalp and hair health.
