What To Do If Your Blonde Hair Turns Green

Why blonde hair can turn green

There are a number of reasons why your blonde hair may have turned green. If you’re using a box colour, or if you’re getting your hair coloured by a professional stylist who isn’t using the proper technique, the cause could be chemical exposure.

If your hair comes into contact with chlorine or other chemicals commonly found in water, oxidization can cause a green tint to emerge. Copper is usually to blame for this as chlorine and copper bond together to form a film that then sticks to the proteins in your hair.

How to fix blonde hair that has turned green

If your hair has turned green, there are some things you can do:

Swimmers Green – Using a shampoo that will remove chlorine and chemical build ups is a must. We recommend Keune Sun Shield Shampoo used in conjunction with Sun Shield Oil. It is recommended that if you swim more that 2 times per week, this becomes your regular routine.
Use a purple shampoo such as Keune Silver Savior: This will help tone unwanted colour from your hair and will balance the tone. Apply the product to wet hair and rinse thoroughly after 10 minutes.
Use a purple conditioner or toner: You can use either of these on top of the shampoo every few washes. These products are also great stand-alone treatments for preventing your hair from turning green in the first place.
Use a dedicated purple mask: Again, you should incorporate this into your haircare routine once per week to prevent your hair from changing colour.
Deep Salon Cleanse – come into the salon and we can do a deep cleanse and treatment on your hair, prescribe options for you to maintain your hair and eliminate the green.

It’s important to note that these aren’t immediate fixes – it will take time for your hair to return to normal. The best option is to see a professional hair colourist who will be able to advise on the best course of treatment.

How to prevent green hair

Use a colour-safe shampoo and conditioner: The most important thing is to choose products designed for blonde hair, as they’re made with ingredients that are less likely to affect the integrity of your colour and hair.
Use a multi-step treatment: These treatments often contain oil or leave-in conditioners, which can soak into the hair shafts better than the water in regular shampoos and conditioners do.
Use a toner: If you want some extra protection against green stains (and who doesn’t?), try using a toner after shampooing and conditioning. Just make sure to rinse it off completely (leave it on for 5–10 minutes).
Wear a swimming hat: If you’re a keen swimmer, make sure to always wear a swim hat in chlorinated water. Never jump into a pool with dry hair either as this is going to suck up the chlorinated water very quickly.
Install a showerhead filter: Even if your water isn’t hard, copper piping could contribute to mineral deposits, so installing a showerhead filter will help remove these from your water.

See a professional hair colourist for any kind of hair colouring

If you’re not sure how to fix your green hair or you want to prevent this from happening in the first place, it’s best to see a professional hair colourist. They will know exactly what to do and can also advise you on how to prevent your hair from turning green in the future. DIY colour kits may be cheap, but you are putting your hair at risk of uneven tones and colours.

Keratin vs Nanoplasty: What You Should Know Before Booking

By Constance Zaborov • September 30, 2025

You’ve likely heard of keratin and nanoplasty hair straightening treatments, but how do you know which is right? Whether you have Afro hair, curly hair, or are seeking smooth, frizz-free locks, understanding the core differences between these two popular options can help you make the best decision for your hair goals. Permanent and non-permanent straightening treatments offer different results, maintenance levels, and longevity. If you're contemplating an appointment and aren’t sure whether you’re after a temporary refresh or a long-term change, this guide will break down everything you need to know—clearing up confusion, busting myths, and ensuring you feel confident before committing to either option. Let’s explore the key differences between keratin and nanoplasty so you can decide which path suits your lifestyle, hair type, and preferences. Understanding Keratin Straightening & How It Works Keratin straightening is a smoothing treatment, not a restructuring one. It infuses hair with keratin, a naturally occurring protein in hair to coat the outer layer, reducing frizz and enhancing shine without changing the internal structure of the hair shaft. This is considered a non-permanent straightening option, and it is ideal for clients who want to try smoother hair without committing long-term. Key characteristics of keratin treatments: Offers semi-permanent frizz control and shine. Results typically last 3–6 months, depending on hair type and aftercare. Works best for mildly wavy, frizzy, or dry hair. Doesn’t cause long-term damage when applied professionally with the right product. Great for busy people wanting to reduce blow-drying time or tame seasonal humidity with a natural-looking finish. The Science Behind Nanoplasty Treatments Nanoplasty goes several steps further than keratin by changing the hair's internal structure using nanotechnology and active ingredients like amino acids, collagen, and botanical acids. The nanoplasty treatment not only smooths and straightens hair from within but also offers that dramatic look and longer-lasting results. This permanent hair straightening service is perfect for anyone seeking a noticeable transformation. Safe for pregnant clients and those looking for a non-invasive method, the nanoplasty treatment offers a smooth, effortless experience with no downtime. At our Sunshine Coast salon, we use only natural ingredients, including amino acids, açai, and linseed oil. Plus, after your treatment, you’re free to enjoy hair colouring without any restrictions! Key benefits of Nanoplasty: Offers sleek, straight hair for up to 8–12 months. Suitable for a broader range of hair types, including coarse, curly, and ethnic hair textures. Free from harsh chemicals like formaldehyde. Leaves hair glossy and manageable with less need for heat styling. The effect doesn't wash out because it alters the hair’s inner bonds—it grows out over time. How Long Do the Results Last? Both treatments leave your hair sleek and smooth, but the duration of results varies between services. The best way to choose the right treatment for you is to consider your budget and how often you’re willing to repeat the sessions.
