Understanding hair loss
Male pattern hair loss is the most common cause of thinning hair in men, often beginning with a receding hairline or thinning at the crown. It can develop gradually, but recognising the early signs gives you the opportunity to explore treatment options.
Whether you're noticing the first signs of thinning or have been experiencing hair loss for years, ZETT makes it simple to explore evidence-based treatments through a confidential online questionnaire reviewed by experienced UK-based clinicians. Your hair, your decision.
