    Need to Know

    Frequently Asked Questions

    What does Strand Defender Conditioner do?
    It's a conditioner made to strengthen and protect fragile, thinning strands. With vegan keratin, marine collagen, and antioxidant-rich botanicals, it helps reduce breakage, smooth frizz, and support healthier, more resilient-looking hair over time.
    How do I use it?
    After shampooing, apply it evenly from mid-lengths to ends, focusing on areas prone to dryness or breakage. Leave it on for one to three minutes so the strengthening ingredients can absorb, then rinse thoroughly.
    Should I apply it to my scalp too?
    It's best applied from the mid-lengths through the ends, where hair is older and more prone to dryness and breakage, rather than concentrated on the scalp. This helps condition where strands need it most.
    Is it a standalone solution for thinning hair?
    It's a supportive part of a hair care routine that helps protect and strengthen existing strands, but it works best paired with Nutrafol's supplement, which addresses thinning from within. Together they offer more complete support.
    Can I use it on all hair types?
    Yes, it's suitable for all hair and scalp types. Use it regularly after shampooing, and avoid contact with the eyes; if any irritation occurs, discontinue use.
