Ah, the joys of summer! Sun, holidays, and refreshing dips in the pool. But for us salon professionals, that often means one thing: the dreaded green cast on our clients’ hair. It’s a common scenario – a client sits in your chair, looking a bit sheepish, with hair that’s taken on an unmistakable verdant hue. Don’t panic! This isn’t an insurmountable challenge; it’s an opportunity to showcase your expertise and gentle touch. As fellow stylists, we know the importance of not just fixing a problem, but doing so in a way that preserves the integrity and health of the hair. This is where the power of professional diagnosis and gentle solutions, particularly demi-permanent colour, truly shines.
Understanding the Green Cast: It's Not Just Chlorine
Before we dive into solutions, let’s clear up a common misconception. While chlorine gets all the blame, it’s not actually the chlorine itself that turns hair green. The real culprit is copper. Many swimming pools use copper-based algaecides, or the copper can leach from pipes in older plumbing systems. When chlorine oxidises these copper particles, they become highly attracted to the protein in your client’s hair. This is especially true for porous hair – think lightened, bleached, or chemically treated strands – which has an open cuticle layer, making it far more susceptible to absorbing these metallic deposits. The copper then binds to the hair shaft, and voilà, you have a lovely green sheen. Understanding this science helps us approach the problem with precision, targeting the metallic build-up directly.
Diagnosis: Getting to the Root of the Problem
Client Consultation is Key
Your first step, as always, is a thorough consultation. Ask your client:
- When did they notice the green cast?
- How often do they swim, and in what type of pool (private, public, saltwater)?
- Have they tried any home remedies? (This is crucial, as some home remedies can exacerbate the issue or further compromise the hair.)
- What’s their hair history? Previous colours, chemical treatments, and general hair health.
Next, perform a detailed visual and tactile assessment. Examine the hair under good lighting. Where is the green most prominent? Is it uniform, or concentrated on the ends or highlighted sections? Feel the hair – is it overly porous, dry, or brittle? This diagnostic phase is vital for tailoring an effective and safe treatment plan.
Patch Test & Strand Test
Never skip these steps, especially when dealing with compromised hair. A patch test ensures no allergic reactions, and a strand test is your best friend for predicting the outcome of your chosen treatment. Take a small, inconspicuous section of hair, ideally where the green is most visible, and apply your proposed solution. This allows you to fine-tune your approach, ensuring perfect results without risking the entire head of hair.
The Treatment Plan: Professional Solutions
Step 1: Chelating or Clarifying First
The first order of business is to remove those stubborn metallic deposits. You cannot effectively neutralise the green if the copper is still clinging to the hair. Professional chelating shampoos or treatments are formulated specifically to bind to and remove mineral build-up. Apply the chelating product to wet hair, ensuring thorough saturation, and allow it to process according to the manufacturer's instructions, usually 5-10 minutes. Rinse thoroughly. For severe cases, you might need to repeat this step. Be mindful that chelating treatments can be quite potent and may leave the hair feeling dry, so preparing for the next steps is essential.
Step 2: Neutralising the Green Tone with Demi-Permanent Colour
Once the metallic build-up is largely gone, it’s time for colour correction. This is where your understanding of colour theory comes into play. To neutralise green, you need its opposite on the colour wheel: red. And when it comes to correcting unwanted tones on compromised hair, demi-permanent colour is your absolute hero.
Why demi-permanent? It’s gentle, ammonia-free, and doesn't lift the natural hair pigment. This means you can deposit the corrective tone without further damaging already fragile hair. It provides a beautiful, translucent wash of colour that fades gracefully, avoiding harsh demarcation lines, and it's less of a commitment for the client if they wish to change their look later. It’s perfect for adding shine and improving the overall condition of the hair.
For this task, we find KEYLUMA PICTO to be an exceptional choice. It’s an Italian-made, ammonia-free and PPD-free demi-permanent colour with a neutral pH, making it incredibly kind to the hair. With 30 versatile shades, you have the precision to tackle even the most stubborn green casts. The cream activator mixes at a flexible 1:1.2 to 1:1.5 ratio, allowing for controlled application and processing.
Choosing the Right Shade
Your goal is to introduce just enough red to neutralise the green, not to turn the hair red. For a subtle green cast, you might opt for a very light red, red-violet, or even a gold-copper tone from the KEYLUMA PICTO range. For a more intense green, a slightly deeper red or red-orange might be needed. Sometimes, mixing a small amount of a red concentrate into a neutral or clear demi-permanent can give you the perfect custom tone. Always remember your strand test here – it will guide your shade selection and processing time perfectly. Apply the demi-permanent mixture evenly to clean, towel-dried hair, focusing on the green areas. Process visually, checking frequently until the green is neutralised. Rinse thoroughly once achieved.
Step 3: Restoring Hair Health
After chelating and colouring, the hair will benefit immensely from a restorative treatment. Follow up with a deep conditioning mask or a protein treatment, depending on the hair's specific needs. This will replenish moisture, improve elasticity, and seal the cuticle, leaving the hair soft, shiny, and healthy-looking. KEYLUMA's aftercare range includes nourishing masks designed to complement their colour services, locking in shine and condition.
Prevention is Better Than Cure: Client Education
Once you’ve successfully banished the green, empower your client with knowledge to prevent its return. This builds trust and positions you as their go-to hair expert.
- Pre-Swimming Prep: Advise clients to wet their hair thoroughly with tap water and apply a leave-in conditioner or hair oil before entering the pool. This saturates the hair, making it less likely to absorb pool water and its metallic contents. A swim cap is, of course, the ultimate barrier.
- Post-Swimming Care: Encourage immediate rinsing of hair with fresh water after swimming. For frequent swimmers, recommend a gentle clarifying shampoo once a week and regular deep conditioning treatments to keep porosity in check.
- Professional Treatments: Suggest periodic in-salon chelating treatments, especially for those who swim regularly or have very porous hair. Recommend regular demi-permanent glazes, like those offered by KEYLUMA PICTO, to maintain tone, add shine, and keep hair feeling healthy and strong between visits. Its gentle, ammonia-free formula makes it perfect for regular use without compromising hair integrity.
