Blue shampoo is a specially formulated shampoo that contains a blue pigment. The purpose of this pigment is to neutralize unwanted yellow, orange, or brassy undertones that can develop in blonde, platinum, or gray hair. The blue colour in the shampoo works because blue is opposite to orange on the colour wheel, meaning it counteracts those warm tones and helps the hair appear cooler, brighter, and more neutral.
Blue shampoo is typically used by people with lighter hair shades, including platinum blonde, light blonde, and silver hair, as these colours are prone to brassiness or yellowing. The shampoo works by depositing a small amount of blue colour onto the hair, which neutralizes the warm tones.
How Blue Shampoo Helps Hair Extensions
-
Prevents Brassiness in Blonde Hair Extensions: Blonde and light-coloured hair extensions can develop yellow or orange tones over time due to environmental factors like sunlight, chlorine from swimming pools, or the natural oils produced by the scalp. These tones can make the extensions appear dull, lifeless, or unnatural. Blue shampoo helps neutralize these brassy hues and keeps the blonde hair looking cooler and more vibrant.
-
Maintains the Freshness of Light-Coloured Extensions: Whether you have balayage, highlights, or full blonde hair extensions, blue shampoo helps to maintain the colour by reducing the appearance of yellowing. Over time, blonde hair can become a bit dull or lose its cool tones, especially if you’ve recently dyed the extensions or they’re exposed to factors like heat styling, pollution, or hard water. Using blue shampoo helps keep the blonde tones fresh, giving your extensions a polished, salon-fresh look.
-
Enhances Silver and Platinum Extensions: If your hair extensions are silver or platinum blonde, they can be especially prone to turning yellow or gaining a warm, brassy undertone. Blue shampoo is essential for people with silver or white hair extensions because it helps maintain the cool, ashy tones that are desirable in these shades. Without blue shampoo, the extensions may start to look dingy or yellow, which diminishes the overall appearance and vibrancy.
-
Prolongs the Life of Hair Extensions: Like natural hair, extensions can lose their luster and vibrancy over time. The process of washing, heat styling, and exposure to environmental elements can make blonde extensions appear more yellowish. Blue shampoo not only helps tone the extensions but also plays a role in maintaining their vibrancy for a longer period. By using it occasionally, you can reduce the frequency with which you need to refresh the colour of your extensions, ultimately helping them look better for longer.
-
Gentle on Hair Extensions: One of the great things about blue shampoo is that it can be used on both natural hair and hair extensions. Since most hair extensions are either made from synthetic fibers or high-quality human hair, blue shampoo is safe to use as long as it’s used correctly. Extensions made from synthetic hair may not benefit as much from blue shampoo, as the shampoo is designed for natural hair colour tones, but human hair extensions will definitely see the most benefit.
How to Use Blue Shampoo on Hair Extensions:
-
Step 1: Wet your hair extensions thoroughly under lukewarm water (if they’re in a wig or clip-in form, you can rinse them separately).
-
Step 2: Apply a small amount of blue shampoo to the hair, working it through gently with your fingers or a comb. You don’t need a lot of product, as blue shampoo is highly concentrated.
-
Step 3: Leave it on for a short period—typically 2-5 minutes. Don’t leave it in too long, as it can cause the extensions to develop a purplish tint. If you’re unsure, start with a shorter time and check the results.
-
Step 4: Rinse thoroughly with lukewarm water, ensuring that no shampoo residue remains in the extensions.
-
Step 5: Follow with a conditioner specifically designed for coloured hair or hair extensions. Conditioning is essential, as blue shampoo can be drying.
Important Tips for Using Blue Shampoo:
-
Don’t Overuse: Using blue shampoo too frequently can lead to over-toning, where your extensions may take on a blue or violet hue. It's best to use blue shampoo about once a week or as needed, depending on how much brassiness or yellowing you experience.
-
Adjust Timing: If your extensions are very light or you have platinum blonde hair, you may need to leave the shampoo on for a little longer (up to 5 minutes). However, if your hair is darker blonde or a medium shade, you’ll want to rinse it out after 2-3 minutes to avoid an unintended blue tint.
-
Use a Moisturizing Conditioner: Blue shampoo can be drying because of its strong pigments, so always follow up with a hydrating conditioner, preferably one designed for colour-treated hair, to maintain softness and moisture in your extensions.
-
Test First: If you're new to blue shampoo, consider testing it on a small section of your extensions first to see how your hair reacts to the formula.
In Summary:
Blue shampoo is a fantastic tool for anyone with blonde, silver, or gray hair extensions, as it helps to neutralize brassiness and keep the hair looking fresh and vibrant. It’s gentle enough to use regularly on hair extensions (especially human hair ones) and can help maintain their colour, ensuring they stay beautiful and bright. By incorporating blue shampoo into your hair care routine, you’ll be able to extend the life of your hair extensions and keep them looking their best.
