DNA Hair Health Test – For Genetic Answers & Personalised Advice

Uncover the genetic reasons behind your hair loss, thinning, scalp inflammation or poor supplement results — with no blood tests, no video calls, and no clinic visits required.

This at-home DNA hair test uses a quick, painless mouth swab (inside the cheek and lips) to analyse 18 key genetic markers linked to:

• Hair shedding and pattern loss
• Nutrient metabolism (vitamin D, B12, folate, iron)
• Hormonal sensitivity that may affect DHT conversion
• Detox and inflammation
• Scalp irritation, oil balance and skin tone
• Stress-related hair loss

You’ll receive a colour-coded report plus personalised written feedback from Sara G Allison, the Original Harley Street Trichologist — with expert advice on which supplements and products from her award-winning range best suit your genetic profile.

If you’re not ready for a full consultation, this is a great place to start.

You’ll still receive expert input from Sara G Allison, with the option to follow up later if you need more personalised support.
