Addendum's multifaceted Leave-In Conditioner gives new life to hair with nourishing ingredients that instantly moisturize, smooth, and prime each cuticle for long-lasting style.

DOUBLE SHOT supercharged formula is designed for all hair types, but is especially ideal for hair extensions as it supplements natural oils found only in the scalp, creating silky, soft strands that blend seamlessly with one's natural hair. Built-in UV-blocking minerals keep your hair color vibrant over time and minimize fading.

Apply to towel-dried hair before styling and comb through for even distribution. Work from mid-shaft to ends prior to blow-drying to prep the hair and seamlessly blend natural strands with extensions.

For daily care, use as a leave-in treatment to smooth, soften, and nourish the ends.

Double Shot Leave-In Cocktail

$55.00
Leave-In Treatment

Double Shot Leave-In Cocktail

Let’s talk Double Shot

Liquid slip, effortless shine. Hair that feels like itself, only softer.

The only leave-in conditioner you’ll ever need.

Made for extensions

Extensions never get the natural oils from your scalp.

Double Shot puts that moisture back, so they stay soft and blend with your own hair.

Your hair’s new non-negotiable

Finally, a leave-in that does everything.

The formula

Four parts, one pour.

01

The Slip & Shield Complex™ with Detangling Technology

Cyclopentasiloxane • Behentrimonium Chloride • Quaternium-80

Instant satin-slip detangling from the first pass of a comb or brush. Reduces breakage, soothes the cuticle, and delivers a glossy, effortless finish.

02

Weightless Silk Emulsion Base™

Cetearyl Alcohol • Glycerin • Propylene Glycol • Butylene Glycol

Hydration without heaviness or residue. Wraps your hair in a feather-light moisture veil for touchable softness, natural movement, and a non-greasy finish.

03

Hydra-Bond Protein Infusion™

Hydrolyzed Vegetable Protein • Panthenol

Reinforces and conditions without weight, while helping to prevent moisture loss. Ideal for damaged, dry, or chemically treated hair. Essential for extensions that can’t pull moisture from the scalp.

04

Lumi-Sheen Mica Filters™

Mica + Optical Diffusers

Light-reflecting shine with a healthy, dimensional glow. Creates a soft-focus radiance that catches the light. This isn’t a shimmer effect. It’s glossy vitality.

Color, protected

Built-in UV-blocking minerals help keep your color vibrant and slow fading.

Results

What changes, and when.

After first use

Instant detangling, improved slip, touch-soft finish.

After 2–4 weeks

Stronger, more resilient strands with less breakage.

Shine increases, frizz decreases, hair feels healthier overall. Works beautifully for daily or weekly use.

Long-term hair wellness

Hydra-Bond protein strengthens over time, supporting repair, flexibility + bounce.

Maintains moisture levels for sleek, nourished strands day after day. Ideal for color-treated, heat-styled, or textured hair.

How to pour it

Work through towel-dried hair, mid-lengths to ends, before you style.

Use it daily as a leave-in to smooth and soften.

Addendum isn’t just haircare. It’s the professional standard, made personal.
