Black wavy hair often struggles to strike a balance between moisture and definition, especially when waves lose their shape under the weight of heavy creams or oils. The best approach is layering hydration strategically. Start with a sulfate-free shampoo and a light conditioner — hydration should come without residue. When the hair’s damp, apply a water-based leave-in or a lightweight curl activator to maintain elasticity. Finger-detangle or use a wide-tooth comb while conditioning to prevent breakage. Scrunch upward with a bit of styling mousse or gel for a hold that's not too stiff. Air drying works best for softer textures, but gently diffusing on low heat also keeps curls springy. For maintaining shine, use a few drops of argan or jojoba oil only on the ends. Sleep on a satin pillowcase or use a bonnet to prevent overnight roughness and dryness. This helps black wavy hair stay smooth, voluminous, and well-defined without weighing it down or losing its gorgeous texture.
