Make Any Beauty Treatment Last

Make It Last 2 Weeks

Hair Color

"You can keep your hue vibrant longer than six weeks," says Rita Hazan, who dyes the tresses of Jessica Simpson and Jennifer Lopez. Enhance dull color with a clear shine treatment like Clairol Natural Instincts Shine Happy, $7.99, drugstores. "Shiny strands create the illusion that hair is freshly dyed," says Hazan. Conceal grays with a paint-on tint that matches your shade and rinses out (try ColorMark, $19.95, colormarkpro.com).

Pedicure

Let your nails dry for at least an hour before putting on shoes; it's crucial to let the polish set so you're not in need of a pedicure every two weeks. After the first day, exfoliate rough calluses and cracked heels with a foot scrub every time you shower (Freeman Bare Foot Creamy Pumice Foot Scrub, $3.99, drugstores). Before bed, smooth on a rich foot cream that contains glycerin and alpha hydroxy acids to keep skin soft (try Curel Targeted Therapy Deep-Penetrating Foot Cream, $4.99, drugstores).
