There's a difference between a part that's quietly widened and a part that's now showing scalp in every light, not just the unforgiving bathroom one. System 2 is built for that second stage — same three-step logic as System 1, with more backup.

TL;DR: A three-step professional regimen — shampoo, conditioner and leave-on treatment — formulated for natural, untreated hair with progressed thinning. Niacinamide, biotin and caffeine work at the root, while the leave-on treatment adds UV protecting ingredients for the scalp and hair. Clinically and dermatologically tested. Use the full system at least three times a week.

Product Details and Benefits

• Shampoo (300ml): Gently cleanses the scalp, lifting away impurities and excess sebum that can clog hair follicles. A congested scalp undermines everything that follows, so this step does the unglamorous groundwork.
• Conditioner (300ml): Adds moisture and slip without flattening finer strands, helping build resilience so hair is better protected against breakage.
• Leave-on Treatment (100ml): The step that stays. Infused with nourishing ingredients, antioxidants and UV protecting ingredients, it nourishes and revitalises the scalp and improves its overall health and condition.
• UV protection at scalp level: The System 2 treatment carries UV protecting ingredients for both scalp and hair — a meaningful addition when there's less coverage overhead than there used to be.
• Niacinamide: A form of vitamin B3 that helps nourish the hair root and supports scalp health.
• Caffeine: Stimulates hair follicles, improves circulation and helps maintain the skin barrier.
• Peppermint oil and wild mint oil (Mentha Arvensis): The signature Nioxin tingle. Wild mint oil refreshes and invigorates the scalp and promotes circulation; peppermint oil can assist in regulating sebum and controlling oiliness.
• Biotin: Completes the root-strengthening blend alongside niacinamide and caffeine.
• Who it's for: Natural, untreated hair with progressed thinning — where the scalp has become visible. If thinning is still light, System 1 is the better starting point. For coloured, dry or damaged hair, System 3 (light thinning) or System 4 (progressed thinning) are the correct match. Anyone previously on the old System 6 should now be using System 4.
• Clinically and dermatologically tested, and designed to add thickness and fullness where thinning has progressed.

How to Use

1. Cleanse. Apply the shampoo to the scalp and massage evenly. Rinse thoroughly.
2. Condition. Work the conditioner from roots through to ends, then rinse thoroughly.
3. Treat. Apply the treatment to scalp and hair, roots to ends. Do not rinse — leaving it on is the entire point.
4. Repeat. Use the complete three-step system at least three times a week. All three steps, every time.

Pro tip: Since you're using the system three times a week rather than daily, choose which three. Line your treatment days up with your outdoor ones — the long beach day, the round of golf, the Saturday in the garden — so the UV protecting ingredients in the System 2 treatment are on your scalp when the sun actually is. A visible part gets a lot more sun than a dense one, and most people never think to plan for it.
