Nioxin Trial Kit System 5-0

Product Overview

The Nioxin Trial Kit System 5 is a three‑step, salon‑grade hair and scalp treatment designed for chemically treated hair (e.g. bleached, permed, straightened) showing light thinning. 

This kit allows users to test the System 5 regimen (cleansing, conditioning, leave‑in treatment) on a smaller scale before committing to full sizes. It aims to improve hair thickness, maintain moisture balance, protect color, and refresh the scalp environment. 

In short, System 5 is suited for hair that is both thinning and chemically processed—offering targeted care rather than a generic volumizing shampoo. 

Key Features & Benefits

Here are the main claimed features and their benefits. Note that actual results may vary by individual.

Many user reviews (in anecdotal form) note some tingling or mild redness after applying the leave‑in treatment, which the brand sometimes frames as an indicator that actives are working. 

One user comment from a forum:

“I’ve been using Nioxin system 5 for about 2.5 months and I actually think it’s making my hair feel more dull and lifeless. I definitely haven’t seen any regrowth or improvement.” 

This reminds us that individual response can vary.

Why Choose This Product?

Here are arguments one might make in favor of selecting Nioxin Trial Kit System 5 (versus generic treatments or alternatives):

1. Tailored to chemically processed, thinning hair
   Many hair‑thinning regimens are too harsh or not moisture-friendly for color- or chemical-treated hair. System 5 is explicitly designed for that intersection.
2. Trial format reduces risk
   Because this is a trial kit, you can test whether your scalp / hair tolerate it and see preliminary results before buying full sizes.
3. Holistic approach
   Rather than just a shampoo, the regimen addresses scalp cleansing, hair conditioning, and leave-in treatment — a more comprehensive system.
4. Protection + performance
   With features like color protection, smoothing and moisture balance, it’s not just about volume, but maintaining hair health and aesthetics as well.
5. Brand credibility
   Nioxin is a known brand in scalp and thinning hair care, with salon support and marketing. Some consumers trust that more than lesser-known alternatives.
6. Potential for visible change
   Some sources claim visible changes in fullness within ~30 days. 

However, one should also keep realistic expectations: thinning hair is often multifactorial (hormonal, genetic, nutritional, medical). This is a support product, not a cure.
