Long straight hair always looks sleek and elegant, but maintaining its shine and softness takes consistent care. Begin with a moisturizing, sulfate-free shampoo and conditioner that smooths cuticles and adds hydration. Towel-dry gently, then apply a light leave-in conditioner or serum for shine and thermal protection. When using flat irons or blow dryers, keep the heat on medium and always apply a heat protectant spray to prevent dryness. Brush gently with a paddle or boar-bristle brush to evenly distribute raw oils from root to tip. Trim your hair every 8–10 weeks to prevent split ends and maintain a clean silhouette. For nourishment, apply argan or coconut oil sparingly to mid-lengths and tips. Avoid heavy styling products, as buildup can dull the shine. Sleeping on a silk pillowcase helps reduce breakage and frizz overnight. With regular hydration and minimal heat styling, long straight hair stays glossy, smooth, and effortlessly timeless—a perfect base for polished or casual looks.
