Details & care

What it is: A high-performance conditioner that instantly starts working to help strengthen, detangle and protect strands.

What it does: It leaves hair feeling stronger and smoother with touchable softness and glossing shine. This conditioner works to provide an 82% split end mending in one use (in an instrumental study conducted on hair tresses by an independent U.S. research organization). The One product line combines an exclusive marine complex developed with Norwegian sea extract and globally curated active ingredients.

How to use: Mist lightly throughout clean, damp hair from mid-lengths to ends. Style as desired.

Pro tips: For finer hair types, skip the in-shower conditioning step for this lightweight spray. For thick or coarse hair, spray on ends as desired.

Amazing!
This product is AMAZING. 7 squirts in palm and massage into hair. I really don’t like the new formula they did with their Gloss Line, so was able to find this hidden gem, worth it!

Salon quality
[This review was collected as part of a promotion.] I recently started using "The One" products and have been very impressed with the difference I see over high end drug store shampoos. This leave in conditioner is no exception. I bought the starter shampoo kit which included the leave in conditioner and was sold. It makes your hair soft and "piece-y" but it doesn't weigh it down and never looks oily. It makes it look like you just had a salon blow out. I love it. It's also great for a second day smoothing and doesn't appear to create any build up. Super impressed with this whole line of products.

Great product, sprayer needs help
[This review was collected as part of a promotion.] Great product, light, doesn't weigh fine hair down or make it greasy. Only issue is the spray pump doesn't work well. Had to replace the first one I bought because the sprayer just dribbled. Fekkai seems to have issues with whomever designs/manufactures their sprayers because their hair spray nozzle doesn't work well either. Their hair products are terrific though!
