Nioxin Pro Clinical System 3 Leave-In Treatment for Coloured Hair with Light Thinning 100ml

Nioxin Pro Clinical System 3 Leave-In Treatment for Coloured Hair with Light Thinning is a lightweight scalp and hair treatment designed to support fuller-looking hair. Created for dry, damaged or colour-treated hair that’s beginning to feel finer, this leave-on formula works to improve the look of density while helping hair feel stronger and more resilient from root to tip. Key ingredients such as caffeine, niacinamide and mentha arvensis leaf oil help to nourish the scalp, support the hair follicles and provide a refreshing sensation, leaving hair feeling energised and conditioned without heaviness or residue.

This product fits seamlessly into an existing System 3 routine alongside the matching shampoo and conditioner. Applied to towel-dried hair and left in, it’s an easy final step after cleansing and conditioning, helping to add body and a touch of shine while supporting the appearance of thicker hair over time. Ideal for those wanting to care for coloured hair without compromising on lightness or manageability, it leaves the scalp feeling refreshed and hair ready to style.

How to use
How to Use:
Start with freshly washed, towel-dried hair. Apply Nioxin System 3 Leave-In Treatment directly to the scalp, focusing on areas of concern. Gently massage into the scalp and work through the lengths if desired. Do not rinse and style as usual.

Frequency:
Use daily or as directed on the product packaging, ideally as the final step after the System 3 shampoo and conditioner.

Application Technique:
Hold the product close to the scalp and apply in small sections to ensure even coverage. Use fingertips to massage the formula into the scalp, then lightly distribute through the hair from roots to ends before allowing it to air-dry or blow-dry.

Best Practices:
Apply to clean, towel-dried hair for best absorption. Use a moderate amount to avoid overloading fine hair. Allow the product to settle before styling and follow with your usual styling products if needed.

Safety Tips:
For external use only. Avoid contact with eyes; if this occurs, rinse thoroughly with water. Discontinue use if irritation occurs and keep out of reach of children. Always follow any additional instructions on the packaging.
