The Science Behind Colour Conditioning
Colouring and bleaching raise the hair cuticle and strip away natural lipids, leaving hair porous, dry, and prone to colour fade. A good conditioner doesn't just make hair feel nice — it actively repairs this damage.
JustK's Colour Protect Conditioner works by depositing a thin protective layer along the hair shaft that smooths the raised cuticle back down. This does two critical things: it seals colour pigment inside the cortex so it can't wash out, and it creates a smooth surface that reflects light — which is what gives hair that glossy, vibrant look.
Argan Oil penetrates deep into the hair shaft to restore lost moisture and strengthen from within. Quinoa Extract's amino acids fill micro-gaps in the damaged cuticle, acting like a protein patch. Together, they rebuild the hair's natural protective barrier that colouring strips away.
How to Use
After shampooing with JustK Colour Protect Shampoo, gently squeeze excess water from hair
Apply a generous amount from mid-lengths to ends (avoid the roots for fine hair)
Use fingers or a wide-tooth comb to distribute evenly and detangle
Leave for 2–3 minutes to allow the active ingredients to penetrate
Rinse thoroughly with cool water to seal the cuticle and maximise shine
Tip: For an extra-deep treatment, leave conditioner on for 5–10 minutes under a warm towel. The heat opens the cuticle and lets the Argan Oil and Quinoa Extract penetrate deeper.
FAQs
Do I need to use the matching shampoo?
The shampoo and conditioner are formulated to work together for best results, but the conditioner will still deliver great benefits with any sulfate-free shampoo.
Will this weigh down my fine hair?
No. The formula is lightweight and designed to condition without leaving residue. If you have very fine hair, just focus application on the ends rather than the roots.
How is this different from a regular conditioner?
Regular conditioners coat the hair surface but don't address the specific damage caused by colouring. This conditioner is formulated with ingredients that repair colour-related damage and seal the cuticle to prevent pigment loss.
Can I use this as a leave-in conditioner?
It's designed as a rinse-out conditioner. For leave-in protection, apply a very small amount to damp ends only — a little goes a long way.
Is this safe to use on bleached or highlighted hair?
Yes. In fact, bleached hair benefits the most — it's typically more porous and damaged, so the repairing ingredients (Quinoa Extract and Argan Oil) have the most impact.
How long will a 300ml bottle last?
With regular use (2–3 times per week), a 300ml bottle typically lasts 6–8 weeks depending on hair length and thickness.
Is it safe for keratin-treated or chemically straightened hair?
Yes. The sulfate-free, gentle formula is safe for all chemically treated hair.
Key Ingredients
Argan Oil (Argania Spinosa Kernel Oil) — Rich in Vitamin E and essential fatty acids, Argan Oil deeply conditions, smooths frizz, restores elasticity, and creates a protective barrier around the hair shaft that helps lock in colour.
Quinoa Extract (Chenopodium Quinoa Seed Extract) — A complete plant protein with all essential amino acids. It bonds to damaged areas of the hair cuticle, strengthening and repairing the structure weakened by colouring. Helps form a protective film that reduces colour washout.
Rose Oil (Rosa Rugosa Flower Oil) — A luxurious natural conditioner with anti-inflammatory and hydrating properties. Adds radiant shine, helps balance scalp moisture, and provides the conditioner's beautiful, gentle fragrance.
Glycerin — A natural humectant that attracts and holds moisture in the hair, keeping it soft and hydrated between washes.
Tocopherol (Vitamin E) — An antioxidant that protects hair from UV damage and environmental stressors that cause colour to fade prematurely.
