There are a few reasons why grey hairs start to appear, and for most of us, it is simply part of life. Whether your first silver strands show up early or later on, your hair colour journey is personal, and Garnier is here to help you understand what is happening and how to care for your colour with confidence.
Age and genetics
Grey hair appears when your hair produces less melanin, the natural pigment that gives hair its colour. As melanin production slows down, strands can start to look grey, silver or white.
Genetics also play a big role. If grey hair appeared early in your family, you may notice those first silver strands sooner too. The good news? With the right at-home hair colour, you can help blend or cover greys while keeping your result soft, radiant and natural-looking.
Health and lifestyle factors
Your hair often reflects what is happening in your body. Certain health factors may affect the way your hair looks, feels or changes over time. If you notice sudden greying, hair thinning or a major change in texture, it is best to speak to a healthcare professional for personalised advice.
Diet and nutrient balance
Healthy-looking hair starts with everyday care, and that includes what you put into your body. Nutrients such as vitamin B12, iron and copper help support overall hair health.
A balanced routine, plenty of nourishment and the right hair care can all help your hair feel stronger, softer and more cared for, especially if you colour your greys at home.
Heat styling and chemical treatments
We all love a good blow-dry or a smooth, styled finish, but frequent heat styling, relaxing, perming or chemical treatments can leave hair feeling dry or fragile over time.
While these habits do not directly cause grey hair, they can affect how shiny, smooth and healthy-looking your hair appears. If you are using permanent hair dye to cover greys, follow with nourishing care to help keep your colour looking fresh and your hair feeling soft.
Stress and everyday wellbeing
Stress can affect the body in many ways, including how your hair looks and feels. While grey hair is usually linked to age and genetics, looking after your wellbeing can help support healthier-looking hair overall.
Simple daily habits like getting enough rest, eating a balanced diet and using caring hair products can all help your hair feel more nourished.
