Depending on how long you leave the shampoo in your hair, a silver shampoo can help you achieve a range of blonde shades from sumptuous honey to vibrant white. Natural silver hair tends to be dryer and more porous than hair that still has its former colour, so it can be more prone to absorbing molecules from the environment that leave it looking yellow and dull. Because it’s pale to begin with, natural white-silver hair also tends to show yellow deposits more than coloured hair. Smoke, chlorine, dust, dirt and even sunlight can deposit yellow tones that, over time, appear dirty and dull. A silver shampoo not only removes dirt and cleans the hair shaft, it also deposits a violet-blue pigment that cancels out yellow, leaving natural silver hair looking cleaner and brighter.

For those with ombré hair with blonde ends, only apply the silver shampoo to those sections. You can also use it on orange hair as a similar colour theory applies. There are two main types of grey/silver hair colour that are currently driving the trend train: natural grey hair and coloured silver hair. If you have a full head of blonde hair, apply the silver shampoo evenly. You may find more yellow or brassy tones at the roots of your hair; if this is the case, apply the shampoo to your roots first and leave on for three to five minutes before applying to the rest of your hair.

Both natural and dyed silver hair will benefit from a monthly treatment masque or glossing treatment, to help add shine as well as freshening up colour.

Over the years, our hair gradually turns grey due to a loss of pigment caused by our genes. The melanin-producing cells eventually stop, and when this happens the next hair to grow out of the follicle is white or grey. Once a certain follicle produces a white hair, it will never again produce a coloured hair because it no longer has the necessary colour-producing cells. Also known as a purple shampoo, silver shampoos like L’Oréal Professionnel Série Expert Silver Shampoo,contain a deep purple pigment that act as an anti-yellowing agent to counteract hair brassiness. This neutralises strong yellow tones in artificially blonde, grey or silver hair, helping you maintain a beautiful cool colour. In addition conditioning helps to nourish and protect the hair fibre. Using one regularly can help to keep hair colour vibrant and salon-fresh. Silver shampoo is also perfect for natural grey hair which can develop a yellow tinge from exposure to elements such as wind, rain and pollution. The shampoo can help correct this brassy colour, as well as strengthen hair fibres. Silver shampoos are in vogue, thanks in no small part to the trend for Daenerys Targaryen-inspired white-blonde hair, but blue- and purple-toned silver shampoos have been around for much longer than the kingdom of Westeros. Designed to remove brassy or yellow tones from the hair, silver shampoo keeps natural (or dyed) silver-grey hair looking clean and bright without bleaching or harming the hair. Cool undertones are what make grey and silver hair so stunning. However, a common concern for silver-haired men and women is brassiness, where warmer tones can develop over time, turning hair a brassy shade of orange/yellow. Why is this? There are several possible reasons:For blonde and silver shades, stylists usually use a bleaching product to lighten the hair, followed by a toner. The bleach lifts the colour up to the desired level, while the toner gives it – literally – the tones you want. But this toner can wear off after over-washing/styling, or if not correctly applied, revealing the warmer nuances of the lifted hair beneath. Use purple shampoo as you would any shampoo. Massage a small amount into wet hair, rinse and condition as normal.
