To strengthen and soften:
Use a leave-in treatment Hair serums, lotions and creams designed for aging hair provide a mix of ingredients that strengthen strands, restore moisture, add shine and prevent breakage. (Warning: Theyre potent, so start by adding just a drop to damp hair so it doesnt get greasy!) TRY: Alterna Haircare Caviar Anti-aging Omega+ Nourishing Oil ($38; sephora.com).
To add head-turning shine:
Get a gloss or glaze These salon treatments (on average $20 to $50, depending on location, but sometimes free with salon color service) deposit either a clear or pigmented coating over the length of your strands to smooth the cuticle and increase sheen, and last for up to four weeks. Ask for one at your next cut or color appointment, or use an at-home product once a week after you shampoo and condition. TRY: Rita Hazan Foaming Color Gloss Ultimate Shine ($15; 7yearsyounger.com/shop)
Bonus tip! Try tea for a DIY gloss:
Brew two tea bags in two cups of hot water (chamomile for blondes, rooibos for redheads and black for brunettes) and let it cool, then apply it as a final rinse at the end of your shower. It closes the cuticle, which smooths hair and adds polish, while also boosting color or neutralizing brassiness, says Philip Pelusi, CEO of Tela Beauty Organics. Cost per treatment: 40¢
