Nioxin has been the professional standard for scalp care and thinning hair solutions for over 35 years. Built on the principle that a healthy scalp environment is the foundation of healthy-looking hair, Nioxin's clinically-tested systems work in three steps — cleanse, optimize, and treat — to visibly thicken strands and revitalize the scalp.
The brand's signature 3D Actives technology targets three dimensions of thinning: diameter (thickness), density (fullness), and length. BioAMP technology amplifies the look of each strand while SPF 15 UV protection shields fragile hair from further damage. Each numbered System is formulated for a specific hair type and thinning level, ensuring you get targeted results.
At ProHair.ca, we carry the complete Nioxin professional lineup — from System 1 through 6, Scalp Recovery anti-dandruff, and 3D Intensive treatments — because we know that finding the right system makes all the difference for clients experiencing hair thinning.

Frequently Asked Questions
How do I choose the right Nioxin System?
Nioxin systems are numbered 1–6 based on hair type and thinning level. Systems 1–2 are for natural hair, 3–4 for color-treated, and 5–6 for chemically treated hair. Within each pair, the lower number is for light thinning and the higher for progressed thinning.
How long before I see results with Nioxin?
Most clients notice improved scalp feel and hair texture within 2–4 weeks. Visible density improvement typically appears after 8–12 weeks of consistent daily use. For best results, use all three steps — cleanser, optimizer, and treatment — every day.
Will Nioxin work on male-pattern baldness?
Nioxin is not a regrowth treatment and does not cure male-pattern baldness. However, it significantly improves the appearance of thinning hair by making existing strands look thicker and fuller. For regrowth, Nioxin's Minoxidil topical products are available as a separate companion treatment.
Can I use Nioxin on color-treated hair?
Absolutely. Systems 3 and 4 are specifically designed for color-treated hair. They incorporate ColorLock technology that helps preserve color vibrancy while delivering all the scalp care and thickening benefits.
Is Nioxin safe for daily use?
Yes — Nioxin systems are designed for daily use. The cleansers are gentle enough for everyday washing, and the leave-in treatments are formulated to be worn throughout the day or overnight.
Does Nioxin cause more shedding initially?
Some clients experience a brief increase in shedding during the first 2 weeks as the scalp adjusts and sheds older, weaker hairs. This is normal and typically resolves quickly. If shedding continues beyond 4 weeks, consult a dermatologist.
Can Nioxin be used with other ProHair brands?
Yes. Many clients pair Nioxin's scalp treatment with a separate conditioner suited to their hair type. Avoid heavy conditioning masks on the scalp to maintain the system's effectiveness.
