HRE Tonic is an anti-hair loss scalp tonic. It helps control hair fall, helps strengthen and nourish the hair root and follicle, helps hair look fuller, and helps keep the scalp clean and comfortable. HRE+ is a daily chewable multivitamin, taken alongside it.

Between them they cover the everyday part — a scalp that's properly cared for and nutrition that's covered. If your hair loss is sudden, patchy, or arriving alongside other symptoms, see a doctor first, then build the routine around what you learn.

Either works — they're sold separately and the Tonic is the cheaper way in. Most people end up using both, because they're designed to sit either side of the same day: the Tonic on your scalp before bed, HRE+ with your meals.

The Tonic is the one doing the work on your scalp and hair. HRE+ covers your everyday nutrition. Together it's one routine rather than two, and the three-month programme costs less per month than buying either on its own.

Hair grows slowly, and any routine takes months rather than weeks to be worth assessing. We sell three- and six-month programmes because a month of anything tells you very little.

It's a leave-in formula, so it wants uninterrupted hours on the scalp without being rinsed, brushed out or covered by styling. Bedtime is simply when that's easiest — and it means the routine attaches to a habit you already have.

It contains a full vitamin and mineral complex, so check the labels of anything else you're taking to avoid doubling up — particularly on vitamin A, vitamin K1 and iron. If you're on anticoagulant medication, or unsure, ask a pharmacist first.
