Genetic testing
This non-invasive genetic test analyses 26 polymorphisms related to metabolic pathways and treatment responses. scientifically linked to hair growth, shedding, and follicular ageing. The goal is to match your results with the treatment strategies most likely to work for your biology.
We investigate:
Androgen pathways: Genetic sensitivity to androgens (like DHT) can accelerate miniaturisation and hair thinning. Understanding your response helps us tailor treatments to reduce this impact.
Inflammatory response: Chronic, low-grade inflammation is a silent driver of hair loss. Your test will show whether your immune genes are likely to trigger or prolong this process.
Blood flow & circulation: Certain genes affect the dilation of blood vessels supplying the scalp. Poor circulation means poor delivery of nutrients and oxygen—critical for healthy hair.
Collagen & structural integrity: We assess your genetic collagen blueprint—essential for anchoring hair in the scalp and preserving follicular strength over time.
Nutrient processing: Some people carry variations that impair the metabolism or transport of iron, B vitamins, vitamin D, or other nutrients essential for the growth cycle.
Glucose and insulin sensitivity: Blood sugar regulation impacts hormonal balance and inflammation. Certain genes can reveal how this may be impacting your hair.
Prostaglandin activity: These lipid compounds regulate the hair growth cycle. Your genetic profile helps us understand whether they’re helping or hindering regrowth.
How it works
- Book a hair and scalp assessment: Shannel will assess your suitabilty for genetic testing.
- Sample collection: A painless cheek swab takes just minutes in clinic or can be posted to your home.
- Lifestyle questionnaire: You’ll complete a short digital form to contextualise your genetic data with diet, health status, and hair goals.
- Laboratory analysis: Your sample is processed in a certified genetics lab. Results are returned in around 2–3 weeks.
- Personalised plan: In your follow-up consultation, we interpret your results and build a targeted strategy—covering topical treatments, supplements, lifestyle shifts, and (where needed) medical referrals.
Who this is ideal for?
- Clients with a strong family history of hair loss
- Individuals who have not responded to typical over-the-counter or topical treatments
- Those seeking a root-cause diagnosis before investing in interventions
- Anyone wanting a preventative, science-led approach to preserve hair density
