April showers bring ... you know. But wintered-out, brittle hair could use hydration, too. Treat it before, during, and after shampoos with:
1. Philip Kingsley's Elasticizer Extreme: Apply biweekly to wet hair (mid-length to ends), cover, leave on two to 20 minutes, then shampoo, $45; at philipkingsley.com.
2. Garnier Fructis Damage Eraser Strength Reconstructing Butter: Launched this year, it's fueled by rich, nourishing cupuau butter (from a Brazilian superfruit). Apply to wet hair after shampooing, wait five minutes, then rinse, $5.99; at drugstores, mass market outlets and garnierusa.com.
3. Smooth and soften with Frédéric Fekkai's new PrX Reparatives Mending Elixir. Simply warm the oil in the palms of your hands and smooth over dry hair to tame flyaways and condition dry ends, $25; at Fekkai salons and fekkai.com.
4. René Furterer's Lissea Leave-In Smoothing Fluid coats hair with a light, imperceptible wax derived from French berries. Apply to towel-dried hair, blow dry, then add another drop to strands, $30; at René Furterer salons (call 800-522-8285 or visit renefurterer.com) and beauty.com.
