What Causes Gray Hair

‘What causes gray hair?’ It’s one of the most common questions we hear from clients who are trying to keep silver strays at bay but can’t figure out where they came from. The fact is, there several reasons we get gray hair – from stress to plain and simple genetics. Here, we reveal the full details, plus answers to seven more questions you might have about gray locks…

1. WHAT IS GRAY HAIR? The answer to this is less obvious than you think. Gray hair isn’t merely a hair that goes gray; it’s actually a strand of hair that has lost its pigment entirely. So, while it may look silvery, each ‘gray’ hair is really white or pigment-free. It may take on a grayish appearance when interspersed with other colors.

2. WHY DOES HAIR GO GRAY? Hair goes gray – or, rather, loses its pigment – when the cells responsible for color, called melanin, stop being produced. There’s a host of possible reasons why this might happen, with age being the obvious one. It’s believed that stress, as well as nutritional, hormonal, and genetic factors, can all play a role, too.

3. IS GRAY HAIR COARSER THAN PIGMENTED HAIR? Sometimes, gray hair can feel coarse or wiry. This isn’t a result of the hair losing pigment, but rather another natural process that takes place as we get older. Over time, your hair follicles produce less oil, which can cause this coarser texture. For clients who complain about wiry hair, suggest a hydrating shampoo and a deeply nourishing treatment. We love the Oil Reflections Luminous Reveal Shampoo and Luminous Reboost Mask; a sumptuous duo we’re dubbing a match made in moisture-boosting heaven.

4. WHEN DOES HAIR GO GRAY? The rate at which hair turns gray varies from one person to the next. Some may notice silvery strays in their twenties, while others may spot their first grays in their forties. This is true for every hair color, whether it’s black, brown, blonde, or red. However, those with darker hair may notice their grays sooner than blondes, as the white strands stand out more.

5. WHAT HAPPENS IF YOU USE PURPLE SHAMPOO ON GRAY HAIR? External aggressors, such as chlorine or pollution, can cause gray hair to turn yellow over time. However, clients with yellowing grays can use a purple shampoo to neutralize that warmth. Suggest they turn to the INVIGO Cool Blonde Color Refreshing Shampoo once a week to cool down grays.

6. CAN GRAY HAIR BE COLORED? Yes. Although some grays can be resistant to color, there are several options for clients who hope to hide their silver strays. Every gray coverage service begins with choosing the right color product, so talk your client through the options. Here are our ‘goodbye gray’ go-tos…

DEMI-PERMANENT OR SEMI-PERMANENT COLOR For clients who prefer a demi- or semi-permanent hair color, you can achieve anywhere between 30% and 70% gray coverage. Color Fresh gives you up to 30% with a subtle, true-to-tone tint, while Color Touch offers up to 70% with a vibrant and intense finish to boot. Choose one of these hues for a softer demarcation line when roots grow out.

PERMANENT HAIR COLOR This is the color for clients who hope to hide every single gray, offering up to 100% coverage in a range of shades. Choose Illumina Color for a sheer, light-reflective result or Koleston Perfect for a pure, healthy-looking finish. Then, mix the chosen color 1:1 with 6% Welloxon Perfect Developer for maximum coverage.

HIGH LIFT SHADES AND HAIR LIGHTENER You can take a client’s hair from gray to blonde with a hair lightener or high-lift color. Choose your favorite Blondor product for highlights, Blondor Freelights for balayage, or one of Koleston Perfect’s Special Blondes for lightener and toner in one. Mix the latter with Welloxon Perfect 12% for up to five levels of lift or 9% for up to three levels.

7. WHAT TECHNIQUES SHOULD I USE TO COLOR GRAY HAIR? There are three key Wella services we use to keep gray hair under wraps. Choose from a simple Root Touch Up, an Express Touch Up, or Gray Blending. For minimal strays, you can also cover gray hair with highlights, applying them on or beside silver strands to gently blend them in and make them less noticeable.

ROOT TOUCH UP The traditional, full-head root touch-up sees color applied to regrowth with a tint brush. Do this with a permanent hair color shade of Illumina Color or Koleston Perfect. Go for a hue that either matches the color throughout the mid-lengths or pick one that’s slightly darker to create an oh-so-delicate root shadow.

PARTIAL ROOT TOUCH UP Fast track gray coverage for clients who are tight on time or need a quick pick-me-up. You use the same color products as a normal Root Touch Up but only apply to the parting and hairline. You can speed things up further by using heat to reduce the development time. A Climazon will take the process down from 40 minutes to just 25.

GRAY BLENDING Soft, subtle, and seamless; this service is designed to touch up minimal regrowth, delivering just a hint of a tint to blend away stray grays. Quite simply, you use demi-permanent Color Touch or Color Touch Plus to refresh locks, whether by focusing your client’s chosen shade on the roots or sweeping through to the tips.
