Eighty percent of women over 50 color their hair, but gray is just one of six visible signs of aging hair (the others include: change in texture, diminished density, increased dryness, surface dullness and fragility/breakage).

Scientists at Redken research have identified two main categories of aging hair: Chronological aging caused by mechanical, environmental and chemical distress (the combined effects of these external factors can leave hair dry, sensitized and/or porous) and Hormonal aging, which occurs as a result of the physiological changes that women experience as they grow older. “This ultimately results in slowed scalp activity and the decline in melanin, the hair’s natural source of protection and defense against age-accelerating aggressors,” says David Cannell, Redken Research and Development Expert.”

To the rescue: Redken’s new age-defying regimen. The routine starts with Cover Fusion professional haircolor, a fast-acting, low-ammonia color cream that completely covers grey while strengthening strands and boosting shine. Keep up the results at home with Time Reset, an at-home hair care range that includes a shampoo, conditioner, replenishing deep treatment and protective softening lotion. Between color appointments, treat hair to a Time Reset Salon Service, a super-targeted, in-salon treatment containing peptides, ceramides, antioxidants, UV blockers, conditioners and a patented “Intra-Cyclane” technology that promises to even hair porosity and improve strand resilience.

If all this sounds overly technical, consider this: In a salon study, 94 percent of professionals observed an improvement in hair manageability, 77% detected enhanced hair density and 88% reported an increase in shine or brilliance.

Enough said.
