NIOXIN Hair Fall Defense Intensive Daily Leave-In Serum, 2.3 fl oz — Niacinamide & Caffeine for Thicker, Stronger Hair

NIOXIN Hair Fall Defense Intensive Daily Leave-In is a lightweight scalp serum formulated with niacinamide, caffeine, lauric acid and SANDALORE™ to strengthen hair anchorage and visibly reduce shedding with daily use.

Designed for thinning or fragile hair, this leave-on serum from NIOXIN Pro Clinical targets the scalp to support stronger strands and fuller-looking hair. Developed from a double-blind clinical study, the formula combines active botanicals and targeted molecules intended to nourish follicles, improve hair resistance and deliver visible improvements in anchorage over time while offering immediate thicker look-from-root benefits.

How does this treatment reduce hair fall and improve anchorage?

The formula targets the scalp environment to help roots hold hair more firmly, using actives that support follicle health and strand integrity. In clinical testing, users reported measurable increases in hair anchorage and less hair shedding when used daily.

• Niacinamide helps support scalp condition and lipids around follicles.
• Caffeine works as a stimulant-like ingredient to energize the scalp area.
• SANDALORE™ is included to interact with follicle receptors and support anchorage.
• Lauric acid and lightweight emollients strengthen strand resistance to breakage.

What results can I expect and how quickly will I see them?

Visible improvements in hair anchorage were observed on average within eight weeks in a controlled study, and many users notice a thicker appearance from the first application thanks to root-targeted formulation. Consistent daily application yields the most reliable outcomes.

• Immediate cosmetic thickening at the root with daily use.
• Average, study-based anchorage improvements around eight weeks.
• Reduced breakage and improved hair resistance reported by participants.
• Free from parabens, sulfates and artificial colorants for everyday use.

How should I apply the leave-in serum for best results?

Use the treatment daily on a clean, dry or towel-dried scalp. Apply directly to thinning areas and massage gently to distribute; leave the serum in—do not rinse—so the actives can work throughout the day and night.

• Part hair into sections to expose the scalp where needed.
• Dispense a few drops onto the scalp and massage until absorbed.
• Style as usual—no rinsing required; compatible with other styling products.
• Consistent daily application is key for study-like results.

Is the formula safe for colored or chemically treated hair?

The leave-in serum is free of parabens, sulfates and colorants and is formulated to be gentle for routine use on color-treated or chemically processed hair. As with any new product, test on a small area first if you have sensitive scalp concerns.

• No parabens, sulfates or added colorants in the formulation.
• Lightweight texture that won’t weigh down fine hair.
• Suitable to layer under styling products and oils.
• Patch test recommended for very sensitive scalps.
