Long & Strong Conditioner is the second step in Keune’s award-winning Long & Strong hair and scalp routine, which won a 2026 Dutch Beauty Award in hair care. This intensive yet lightweight conditioner is made for weakened, fragile hair. It nourishes and strengthens each strand, leaving hair smoother and more resistant to daily stress and breakage, without weighing it down.
Strengthen and fortify: Marine Density Infusion (dulse seaweed extract) and plant proteins help strengthen strands, so hair looks and feels fuller.
Nourish: Castor oil, shea butter, and glycerin hydrate and nourish to help reduce breakage.
Detangle and soften: It eases combing and repairs the look of styling damage.
Shine: Used with the Long & Strong Shampoo, it gives up to 76% more shine.
It’s light enough for fine or thin hair and leaves it fuller and healthier-looking. The formula is vegan, gluten-free, and cruelty-free.
After shampooing with Long & Strong Strengthening Shampoo, gently squeeze out excess water.
Apply to mid-lengths and ends, avoiding the scalp.
Leave on for 1 to 3 minutes.
Rinse thoroughly.
For best results: Follow with Long & Strong Super Serum on the scalp and Densifying Leave-In on the lengths.
All hair types and textures, especially fine, thin, fragile, weakened, or breakage-prone hair, and seasonal or postpartum shedding. It’s ideal for anyone wanting stronger, smoother, fuller-looking hair. Safe for colour-treated hair.
