5 BEST… PRODUCTS FOR BLONDE HAIR

1 The shampoo: John Frieda Sheer Blonde Highlight Activating Shampoo, £6.99, is now enriched with avocado oil to nourish and reactivate faded highlights for a brighter blonde hue.

2 The conditioner: Redken Colour Extend Blondage Conditioner, £17, is a colour-depositing conditioner, which tones down brassiness and delivers a visibly brighter blonde.

3 The corrector: Charles Worthington Colourplex Toning Violet Shampoo, £7.99, can be left on for a few minutes to neutralise yellow tones and strengthen hair.

4 The brush: Tangle Teezer Wet Detangler, £11, goes gentle on hair. This is particularly good for hair that has been bleached and is therefore more tangle-prone and fragile.

5 The temporary touch-up: Josh Wood Colour Root Marker, £8, is a handbag must-have that colours over grey hair and comes in six shades for blondes.
