Description

Damaged hair can become rougher, harder to detangle and more vulnerable to breakage through everyday handling. This lightweight mist smooths and softens the lengths while improving manageability, helping reduce breakage and split ends for hair that feels easier to handle and looks healthier.

Hydrolyzed Keratin helps reinforce compromised lengths, supporting a smoother, stronger-feeling finish. As the formula conditions the hair surface, reduced friction can make detangling easier and limit the mechanical stress associated with breakage.

The lightweight mist format keeps conditioning effortless while adding softness and shine. Hair is left smoother and easier to manage, with a healthier, more resilient-looking finish.

How to use
  1. Mist evenly onto clean, damp hair, focusing on the mid-lengths and ends.
  2. Work through gently with your fingers, smoothing and detangling the lengths for even distribution.
  3. Leave in. Do not rinse. Style as usual.
Who's it for

Ideal for rough, tangled or damaged hair that needs lightweight leave-in conditioning without the weight of a rich cream.

Especially well suited to hair that is easily weighed down but still needs softness, smoothness and easier detangling.

Ingredients

KEY INGREDIENTS

Hydrolyzed Keratin

Hydrolyzed Keratin provides smaller protein fragments that can interact with porous, compromised areas and temporarily deposit along the hair surface. This helps smooth roughness and improve slip, supporting easier detangling and stronger-feeling lengths while helping reduce the friction-related mechanical stress damaged hair can experience during everyday handling.

Algae Extract

Algae Extract provides complementary conditioning support, helping maintain softness and a smoother, more flexible-feeling finish through stressed lengths. Alongside Keratin’s protein-based surface support, it adds a softer conditioning dimension that helps damaged hair feel more manageable and polished.

THE FORMULA

SMOOTHING SUPPORT + LIGHT CONDITIONING

Hydrolyzed Keratin

Hydrolyzed Keratin can temporarily deposit along porous, compromised areas of the hair surface, helping smooth roughness and improve slip for easier everyday handling.

Algae Extract

Algae Extract adds complementary conditioning support, helping lengths feel softer, smoother and more flexible with a polished, manageable finish.

Frequently asked questions

Can I use it after Conditioner?

Yes. Conditioner is your rinse-out step, while the Leave-In Mist stays in after washing for lightweight smoothing and easier detangling.

Will it weigh my hair down?

It’s designed as a lightweight leave-in that smooths and conditions without the heavy, coated feel of a richer cream.

When should I choose the Hair Mask instead?

Choose the Hair Mask when dry, damaged or fragile-feeling lengths need a richer, more intensive treatment. Choose the Leave-In Mist when you want lightweight smoothing and easier detangling after washing.
