How to Use Jerome Russell ProColour 4.0 Dark Brown for Best Results:
Achieving your stunning new dark brown hair is a straightforward process with Jerome Russell ProColour. Always read the enclosed instructions thoroughly before you begin.
- Safety First: Perform a Skin Sensitivity and Strand Test: Absolutely crucial! 48 hours prior to full application, apply a tiny amount of the mixed product behind your ear or on your inner elbow. Wait 48 hours to check for any adverse reactions. Simultaneously, perform a strand test on a small, hidden section of your hair to determine precise timing for your desired dark brown shade and to ensure the end result is exactly what you envision. This step is vital for safe and satisfying permanent hair colouring.
- Prepare & Mix Your Colour: Put on the protective gloves provided. Open the colour cream tube (Tube A) and squeeze the entire contents into the applicator bottle (Bottle B) containing the developer. Securely replace the applicator bottle cap and shake vigorously for 30-60 seconds until the mixture is thoroughly blended and uniform. Immediately cut off the tip of the applicator nozzle to prevent bursting. Your Jerome Russell ProColour 4.0 Dark Brown mixture is now ready for application.
- Apply Evenly to Dry Hair: Starting at the roots, apply the permanent dark brown hair dye mixture evenly throughout your dry, unwashed hair. Ensure every strand, especially areas with grey hair, is fully saturated for consistent dark brown hair coverage. Gently massage the colour through your hair for even distribution. Leave the product on for the recommended processing time indicated in the instruction leaflet (typically 20-30 minutes, or longer for stubborn greys, based on your strand test).
- Rinse, Condition & Finish: Once the processing time is complete, thoroughly rinse your hair with warm water until the water runs clear. Then, apply the included conditioning treatment, focusing on the mid-lengths and ends. Leave on for 2-5 minutes, then rinse thoroughly. Style as usual and admire your new, beautifully vibrant dark brown hair with exceptional shine. This final conditioning step is crucial for sealing in colour and leaving your hair feeling soft and lustrous after at-home permanent hair colouring.
Ingredients Deep Dive for Healthier Hair Colouring:
Jerome Russell ProColour 4.0 Dark Brown isn't just about intense colour; it's also formulated with ingredients that care for your hair. While PPD and Resorcinol are essential for permanent hair colour, we strive to enhance the experience with beneficial additions.
- Argania Spinosa Kernel Oil (Argan Oil): Renowned for its nourishing and restorative properties, Argan Oil helps to moisturise and add incredible shine, leaving your dark brown hair feeling silky smooth and looking radiant. It’s a key ingredient in ensuring your permanent hair colour doesn’t compromise hair health.
- Hydrolyzed Keratin: A protein vital for hair strength, Hydrolyzed Keratin helps to fortify strands, repair damage, and reduce breakage during and after the colouring process. This contributes to healthier, more resilient dark brown hair.
- Ascorbic Acid (Vitamin C): Acts as an antioxidant, helping to protect hair from environmental damage and contributing to the stability and longevity of your vibrant dark brown hair colour.
- Conditioning Polymers: These ingredients help to smooth the hair cuticle, detangle, and enhance the overall feel and manageability of your hair post-colouring, delivering a professional finish to your at-home hair dye application.
- P-Phenylenediamine (PPD) & Resorcinol: Key active colourants for permanent dark brown shades, carefully balanced for effective, long-lasting colour.
- Ammonium Hydroxide: An essential alkalizing agent that helps to open the hair cuticle, allowing colour pigments to penetrate for a truly permanent dark brown hair colour.
These carefully selected ingredients work in harmony to provide a brilliant dark brown hair colour while maintaining the health and vitality of your hair.
Maintenance & Aftercare for Your Jerome Russell Dark Brown Hair:
To ensure your Jerome Russell ProColour 4.0 Dark Brown remains vibrant and lustrous for as long as possible, proper aftercare is key. Use colour-safe shampoos and conditioners that are specifically formulated to protect coloured hair from fading. Minimize washing frequency, use lukewarm water, and consider incorporating a weekly hair mask for deep nourishment. Protect your dark brown hair from excessive sun exposure or chlorine, which can strip colour and cause dryness. With the right care, your permanent dark brown hair colour will continue to look fresh and stunning, reflecting the professional quality of Jerome Russell hair products.
