Nioxin Buyer's Guide
Which Nioxin System Is Right for Me?
Nioxin systems are organized by hair type and level of thinning. Choose the system that matches both your colour or chemical history and the stage of thinning.
System 1
For natural, uncoloured hair with light thinning.
Includes Cleanser Shampoo, Scalp Therapy Conditioner and Scalp + Hair Thickening Treatment.
System 2
For natural, uncoloured hair with progressed thinning.
Includes Cleanser Shampoo, Scalp Therapy Conditioner and Scalp + Hair Thickening Treatment.
System 3
For coloured or chemically treated hair with light thinning.
Includes Cleanser Shampoo, Scalp Therapy Conditioner and Scalp + Hair Thickening Treatment.
System 4
For coloured or chemically treated hair with progressed thinning.
Includes Cleanser Shampoo, Scalp Therapy Conditioner and Scalp + Hair Thickening Treatment.
Each 3-step regimen is sold as a kit, as a litre duo with shampoo and conditioner refills, and as individual full-size pieces. The Scalp + Hair Thickening Treatment is the leave-in step that delivers the active thickening technology, so it should not be skipped.

How to Use the Nioxin 3-Step System
- Cleanse: Apply the matching Cleanser Shampoo to wet hair, massage into the scalp and rinse. This helps remove sebum, environmental residue and follicle-clogging buildup.
- Condition: Apply Scalp Therapy Conditioner from scalp to ends. Leave on briefly, then rinse thoroughly.
- Treat: Apply Scalp + Hair Thickening Treatment directly to the scalp. Do not rinse. Style as usual.
For best results, use the complete 3-step system consistently rather than mixing only one step into another routine.
How to Add Nioxin Boosters
Night Density Rescue
Apply at night to the scalp and leave in while you sleep. It can be layered into a daily Nioxin routine for additional overnight density support.
Diamax Advanced Hair Thickening Xtrafusion Treatment
Use on areas where the hair needs more visible diameter and density. It is designed to help each strand feel thicker and fuller.
Hair Fall Defense Serum
Use with the matching shampoo when the main concern is breakage-related hair fall. This option is focused on strengthening and reducing visible hair fall due to breakage.
Thickening Styling Products
Use after your treatment step when you want more lift, body, grip or hold. Styling products are not replacements for the 3-step scalp regimen.
Frequently Asked Questions
Does Nioxin regrow hair?
Nioxin is designed to improve the look and feel of thinning hair by supporting scalp care, strengthening the hair fibre and increasing visible fullness. It is not positioned as a prescription hair regrowth treatment.
Which Nioxin system should I use for coloured hair?
Use System 3 if your coloured or chemically treated hair has light thinning. Use System 4 if your coloured or chemically treated hair has progressed thinning.
Which Nioxin system should I use for natural hair?
Use System 1 if your natural, uncoloured hair has light thinning. Use System 2 if your natural, uncoloured hair has progressed thinning.
Can I use Nioxin every day?
Yes, the 3-step systems are designed for regular use. Consistency is important because the scalp treatment is a leave-in step that supports the system's visible thickening benefits.
Do I need all three steps?
For the intended system result, yes. The cleanser, conditioner and leave-in treatment are designed to work together. Skipping the treatment step reduces the benefit of the regimen.
What is the difference between a kit and a litre duo?
A kit gives you the complete starter regimen, including cleanser, conditioner and treatment. A litre duo gives you larger shampoo and conditioner refills, but the treatment is purchased separately.
Is Nioxin only for severe thinning?
No. Systems 1 and 3 are intended for light thinning, while Systems 2 and 4 are intended for progressed thinning.
Can I use Nioxin with styling products?
Yes. Use the treatment step first, then apply Nioxin styling products such as mousse, thickening spray, gel, dry shampoo or hairspray as needed.
What is Hair Fall Defense best for?
Hair Fall Defense is best for clients concerned with visible hair fall caused by breakage. The shampoo and serum are designed to be used together.
What is Night Density Rescue used for?
Night Density Rescue is an overnight scalp serum used to support density while you sleep. It is applied to the scalp and left in overnight.
What is Diamax used for?
Diamax is used to help increase the feel of hair diameter and create a thicker, fuller appearance on fine or thinning hair.
Can I mix different Nioxin systems?
It is best to stay within the system that matches your hair type and thinning stage. If your hair is coloured or chemically treated, choose System 3 or System 4 rather than System 1 or System 2.
