REF Leave in Serum

Heat-Protectant Leave-In Serum with Vegan Quinoa Protein

REF Leave in Serum is a lightweight, leave-in styling serum that protects hair from heat styling while adding hydration and slip. Hydrolyzed Quinoa protein — structurally similar to the keratin in hair — works alongside Jojoba Seed Oil and Coconut Oil to support smoothness and a long-lasting detangled finish. The formula is 100% vegan and cruelty-free per the brand. This 125ml bottle is the standard retail size.

Why Choose It?

• Heat protection for blow-drying and hot-tool styling
• Hydrolyzed Quinoa protein adds strength to the hair fibre
• Long-lasting detangling and slip on damp hair
• Lightweight leave-in feel that does not weigh strands down
• 100% vegan and cruelty-free per brand

Best For

Dry, damaged or heat-styled hair that needs a leave-in step for protection, hydration and easier detangling before blow-drying or hot-tool styling. The 100% vegan, cruelty-free formula suits plant-based haircare routines.

For a complete REF wash routine, pair the serum with a matching REF shampoo before applying the serum to towel-dried lengths.

• Wash hair and towel-dry until damp, not soaking wet.
• Dispense a small amount of serum into your palms and rub them together to distribute evenly.
• Work the serum through the lengths and ends first, then lightly up toward the mid-shaft. Avoid the roots.
• Comb through to detangle and even out the product.
• Blow-dry or style with hot tools as usual — the serum supports heat protection during this step.

Tips

• Start with a small dose — a few drops are usually enough for shoulder-length hair. Add more only on the ends if needed.
• Apply on damp hair for the most even spread; on dry hair the serum is harder to distribute and can sit on the surface.
• Focus on the ends and any heat-damaged areas, where Hydrolyzed Quinoa and the conditioning agents have the most to do.
• Close the cap tightly between uses to keep the formula fresh.
