Nutrafol Strand Defender Conditioner

Designed to improve healthier-looking hair and scalp

A lightweight conditioner developed for thinning, fragile or easily damaged hair. It replenishes moisture and supports elasticity while helping reduce the look and feel of breakage without flattening the hair. Apply it after shampooing, concentrating on the mid-lengths and ends, to leave strands softer, smoother and easier to manage.

Strand Defender is a lightweight, physician-formulated conditioner for thinning or fragile hair. Vegan protein and glucose fibers help improve moisture, elasticity and resistance to everyday damage without flattening the hair.

The details that matter

• Clinically tested to replenish moisture and improve hair elasticity.
• Helps strengthen fragile strands and reduce the feel of dryness and breakage.
• Lightweight formula supports smoothness and manageability without heavy buildup.
• Color- and extension-safe for frequent use.

Directions for use

After shampooing, apply through the mid-lengths and ends, using less near the scalp if the hair is fine. Leave on for the labeled time, then rinse thoroughly. It is gentle enough for regular use.

Ideal skin or hair concerns

Thinning, dry, fragile or easily damaged hair that needs conditioning without loss of volume.

A thoughtful routine approach

Pair with Root Purifier Shampoo for a scalp-and-strand routine. Conditioner improves the condition of existing fibers but does not replace medical evaluation of unexplained hair loss.
