When you're slathering on your sunscreen this summer, don't forget to protect your ringlets.
Unlike skin, hair will not become red and painful when it becomes overexposed to the sun so it's more difficult to measure UV protection in hair. But UV exposure can sap the hair of strength and elasticity and cause photo-oxidation, which triggers discoloration and fading in both natural and color-treated hair. According to a study by the Rene Furterer Research Center, after just three days of sun exposure, the scale-like cells that cover each individual hair shaft begin to pull off, making the hair dry, dull and brittle.
"Hair does not get sunburned," says Stephanie Sprankle, manager of education and development for Redken. "But it will fade. If you put a couch in front of a window, the side against the window becomes really faded. It's the same with the hair. You don't want to spend all that money coloring your hair and have it wash away."
A growing awareness of the sun's damaging rays along with technological advances in the hair-care industry have led to a boom in the number of summer hair products this year -- products with names like Sun Bandana, Swim Cap, Sun Veil and Canopy. These products are designed to protect the hair during summertime activities like swimming and sunning, as they moisturize and repair parched locks.
In addition to products specifically designed for use in the summer conditions, such as Hamadi's Shea Spray, a growing number of companies are adding UV protection to their products. Color-treated hair, especially, been treated to a robust selection of UV-protectant products: Paul Mitchell Color Protect Locking Spray, Aveda Color Conserve Sun Protector and Pureology UV Colour Defense.

Unlike skin products, hair products typically are not rated on their sun protection factor (SPF). But the UV filters in hair products protect against the same things as skin products -- UVA and UVB rays, Volpi says Jennifer Volpi, senior manager of marketing for Biolage. Rene Furterer has created a KPF (keratin protection factor) protection measurement rating for its Sun products, the first hair protection rating system. L'Anza Swim & Sun line uses the HPF (hair protection factor) measurement system for its products.
Hair can be best protected from UV damage by treating it with a leave-in product that contains UV filters such as ethylhexyl methoxycinnamate (EHMC), methoxydibenz-oylmethane (BM-DBM) or Parsol SLX.
"I love to spend time in the sun, but I see first hand the damaging effects of the sun on hair," says stylist Frederic Fekkai. "That's why I expanded my Summer Hair collection to help keep hair looking healthy and luxurious all summer long.
Fekkai recently expanded his summer hair line to include five sun-safe formulas designed to protect, hydrate and replenish the hair. They contain ingredients such as Solarshield technology, humectants, sunflower seed extract and moringa seed extract to condition and protect the hair from UV damage, pollutants and environmental stressors.
