Thicker, fuller-looking hair starts here. Nioxin Scalp + Hair System 1 Conditioner 1000ml is a hair-thickening conditioner and scalp treatment made especially for natural hair with light thinning. It works to amplify the texture of each strand and strengthen the hair's resilience, while caring for the scalp, so your hair looks and feels noticeably fuller. And with a generous one-litre bottle, it's brilliant value for committing to the routine.

This is System 1 in the Nioxin range, formulated for natural (non colour-treated) hair that's lightly thinning. It's powered by niacinamide and biotin, which help amplify hair texture and boost resilience to minimise breakage, so more of your hair stays strong and full. At the same time it gently cleanses and nourishes the scalp, removing the impurities and excess sebum that can build up around the follicles, helping to create a healthier environment for your hair. It's clinically and dermatologically tested, with results designed to be visible in around 30 days.

What it does for lightly thinning hair

Hair that's beginning to thin often looks and feels finer and flatter, and breakage only makes that worse by reducing fullness further. This conditioner is designed around exactly that, using niacinamide and biotin to strengthen resilience and minimise breakage, while amplifying the texture of each strand for a thicker, fuller appearance. By also keeping the scalp clean, nourished and healthy, it supports the best possible foundation for your hair. Used as part of the System 1 routine, it's built to deliver visibly thicker, fuller-looking hair over time.

How to use it

After shampooing with the matching System 1 shampoo (cleanser), apply the conditioner through the hair and onto the scalp, distributing evenly. Leave it for a minute or two, then rinse thoroughly. For the best results, use it as part of the full Nioxin System 1 routine. You'll find the matching cleanser and more in our professional shampoo collection.

Who it's for

This one's for anyone with natural, non colour-treated hair that's lightly thinning and wants thicker, fuller-looking results alongside a healthier-feeling scalp. It's clinically and dermatologically tested, and works best as part of the full System 1 routine. We've spent years helping clients in Codsall with all kinds of hair and scalp concerns, and a thickening conditioner like this is one of the easiest ways to support fuller-looking hair between salon visits.
