Nioxin Pro Clinical System 1 Leave-In Treatment for Natural Hair with Light Thinning 100ml

Nioxin Pro Clinical System 1 Leave-In Treatment is a lightweight scalp and hair treatment designed for natural, untreated hair with light thinning. The formula works to refresh the scalp while helping hair look thicker and fuller from root to tip. With a blend of niacinamide, caffeine and biotin, it supports the scalp environment and helps to strengthen each strand, promoting the look of denser, more resilient hair with a healthy-looking shine. The cooling sensation from menthol and mint-derived oils adds a fresh feel to the scalp, making it a comfortable final step in a haircare routine.

Use this leave-in treatment after cleansing and conditioning with the complementary Nioxin System 1 Shampoo and Conditioner. Applied to towel-dried hair and left in, it fits easily into daily styling without weighing hair down. Over time, it helps to improve the appearance of volume and texture, making hair feel more substantial while maintaining softness and movement. It’s a considered choice for anyone beginning to notice early signs of thinning and wanting to care for both scalp and hair together.

How to use
How to Use:
Start with freshly washed, towel-dried hair. Shake the product if directed on the packaging. Apply Nioxin System 1 Leave-In Treatment directly to the scalp, focusing on areas where hair feels finer. Gently massage into the scalp and work any excess through the lengths. Do not rinse and style as usual.

Frequency:
Use daily or as directed on the product instructions, ideally after each cleanse with the matching shampoo and conditioner.

Application Technique:
Apply in small sections to ensure even coverage across the entire scalp. Use fingertips to massage the formula in with light, circular motions, then comb through to distribute from root to tip before drying or styling.

Best Practices:
Apply to clean, towel-dried hair for best absorption. Use as the final step in the Nioxin System 1 three-part routine. Avoid over-applying to lengths to keep the hair feeling light. Patch test before first use if your scalp is sensitive.

Safety Tips:
Avoid contact with eyes. If contact occurs, rinse thoroughly with water. Discontinue use if irritation or persistent redness occurs. Use externally only and keep out of reach of children. Always follow any additional guidance on the packaging.
