Joico K-PAK Color Therapy Luster Lock Glossing Oil — 2.13 fl oz, Lightweight Shine & Color Protection with Keratin & Argan

Joico K-PAK Color Therapy Luster Lock Glossing Oil is a lightweight finishing oil that locks in color vibrancy, increases shine, reduces frizz, and helps protect and strengthen color-treated hair.

Formulated for color-treated and chemically processed hair, this glossing oil blends keratin, argan oil, and manketti oil with Joico’s SmartRelease technology to nourish strands while sealing in color. It’s designed to be used after styling or between washes to smooth the cuticle, add reflective shine, and deliver UVA/UVB protection to slow color fade. The travel-friendly 2.13 fl oz size makes it convenient for touch-ups at home or on the go.

How does this oil help preserve hair color?

The formula includes ingredients that shield hair from environmental and thermal stressors that accelerate fading. SmartRelease liposomes gradually deliver repairing actives—such as keratin and rosehip oil—so protection and conditioning continue after application.

• Helps retain over 80% of color vibrancy for multiple weeks when used as directed
• Contains African manketti oil and UVA/UVB filters to reduce environmental fading
• Works alongside color-safe shampoos and conditioners for best results

Will it make my hair feel heavy or greasy?

This lightweight glossing oil is formulated to add shine without weighing down fine or medium hair. A small amount distributes easily through damp or dry hair to smooth flyaways and enhance polish without residue.

• Use 1–2 drops for fine hair, more for thicker textures
• Apply to mid-lengths and ends to avoid oily roots
• Absorbs quickly for a glossy, non-greasy finish

How does it protect hair from heat and breakage?

Keratin and SmartRelease technology work to reinforce weakened areas of the cuticle and reduce combing breakage, while argan oil provides deep hydration that improves elasticity. The result is hair that handles styling tools with less stress and appears healthier after repeated heat exposure.

• Strengthens hair up to 2X against combing breakage when paired with K-PAK Color Therapy Shampoo
• Shields strands from thermal damage during blow-drying and flat-ironing
• Improves manageability to reduce mechanical wear during styling

How should I use Luster Lock for best results?

Apply a small amount to towel-dried hair before styling to detangle and protect, or smooth a few drops through dry hair for instant shine and frizz control. Consistent use alongside Joico K-PAK Color Therapy products will maximize color longevity and hair strength.

• For daily use: warm 1–3 drops in palms and distribute through lengths
• For styling: apply to damp hair before heat tools; add on dry hair to finish
• Pair with K-PAK Color Therapy Shampoo and Conditioner for best color protection

Who is this for? Joico K-PAK Color Therapy Luster Lock Glossing Oil is aimed at people with color-treated, highlighted, or chemically processed hair who want shinier, smoother-looking hair and extended color life. It suits fine to coarse textures when used in appropriate amounts, and travelers or those who touch up color between salon visits will appreciate the compact bottle.
