New products aim to deliver more youthful hair

As we age, hair loses moisture. To give strands a hydration boost, Pantene has a brand-new collection of products that are rich in B vitamins and promise to help combat everything from dryness to thin strands.SHOP NOW: Pantene Age Defy Collection, from $9

One newly released product holds some promise for thickening hair at the very root. It purportedly improves your hair's health with ingredients such as zinc PCA (a naturally occurring trace element that reduces sebum) and vitamin E (which conditions and plumps follicles).SHOP NOW: Redken Intra-Force Shampoo for Thinning Hair, $16

Elizabeth Cunnane Phillips is Philip Kinglesy’s head trichologist (someone who studies the scalp and hair) in New York. She says, While it's vital to match the correct products and deep moisturizing products to your hair type, it is also crucial that we consider the health of the scalp. This is her recommendation for a deep scalp and hair moisturizer.SHOP NOW: Philip Kingsley Elasticizer Pre-Shampoo Treatment, $47

Hair gets more coarse with age, so heat-protective products can be helpful, says Elizabeth Tanzi, M.D., board-certified dermatologist in Washington, D.C. The brand-new Nexxus Youth Renewal Collection contains a pre-heat-treatment spray and a hydrating finishing serum. Both products are rich in omega 3s, vitamin E, keratin and argan oil, all of which help to smooth the hair cuticle, making hair appear thicker and glossier.

A handy product that coats hair strands, making it look instantly fuller, is a 100 percent keratin colored powder. It works in two ways: It helps to coat the scalp to diminish its show-through. It also clings to hair strands—even the finest—to give the appearance of thicker, darker locks. A perfect choice for commitment-phobes, it washes out easily with shampoo.SHOP NOW: Toppik Hair Building Fibers, from $50

The new G Melé Anti-Aging system is designed to infuse hair with moisture and, thus, subtract years from its look. Made without any harsh chemicals (it's sulfate-free), it contains natural sugars, which its maker claims help lipids adhere to strands. The moisturizing products help to seal the cuticle, preserving the pigments in color-treated hair.SHOP NOW: G Melé Anti-Aging products, from $20

Longer hair goes through a lot: If your hair reaches the middle of your back, the hair at the ends is about eight years old, says White. It has endured many summers in the sun, chlorine and heat styling, and you can definitely use richer products on the ends of your hair than on your scalp. This treatment contains plant-derived melanin to help shield the hair from damaging light—including UVA and UVB rays—while micro-emulsion beads full of fatty acids and vitamins (the caviar) help smooth the cuticle. SHOP NOW: Alterna Caviar Anti-Aging Photo-Age Defense, $35

As we get older, it's important to treat the scalp properly—both exfoliating and moisturizing at the roots, says White. The new Clear hair-care line is aimed squarely at caring for the scalp. To deep-clean your scalp, White says to rinse wet hair with apple-cider vinegar before shampooing. Follow that with a nourishing wash, like this one: It includes aloe; vitamins B5, C and E; as well as sunflower, almond, soybean and coconut oils.

When you color hair, it fattens the strand and makes it look fuller, says White. There have been amazing advances in hair color—L'Oréal just came out with the first no-ammonia oil-based professional color and it literally improves the condition of hair, says White. On the market now for home use is the new Olia line by Garnier (a L'Oréal brand) which also contains no ammonia, and has been getting rave reviews from consumers.SHOP NOW: Garnier Olia Oil-Powered Hair Color, $10

Shine is one of the key ingredients in keeping hair looking youthful, says Oribe. Our new Shine Spray is great because it gives hair luster. You can also use it to blow the hair out, and can also add more afterward for added moisture and shine. This light formula uses argan oil and lemongrass to tame flyaways and add a gorgeous sheen.SHOP NOW: Oribe Shine Light Reflecting Spray, $36
