To add Strength:

get a keratin boost

Is any word in the hair dictionary more terrifying than “breakage”? Weak, splitting strands can feel soul-sapping, but treatments that contain keratin, a protein that forms chains within our hair fibre, can boost you up again (once the total no-hopers on the ends are trimmed off). “Our Hair Filler treatment, £60, uses the purest form of keratin available and penetrates into the hair shaft, filling in gaps from breakage and over-processed areas,” says Salon Sloane founder, Belle Cannan. At home, the most exciting new brand is Virtue, whose Alpha Keratin 60ku complex is made from (ethically sourced) human keratin. I’m addicted to the Restorative Treatment Mask, £26, and Full Shampoo and

Conditioner, from £14. >>
