Getting glass hair at home is very achievable with the right technique and a few key tools. Start in the shower: use a smoothing shampoo and conditioner, then gently squeeze (never rub) your hair dry with a microfiber towel to avoid roughing up the cuticle. Apply a heat protectant and a smoothing cream while your hair is still damp. Blow-dry in sections using a round brush, pulling downward to encourage the cuticle to lie flat. Once fully dry, go over each section with a flat iron using slow, deliberate passes — rushing creates creases. Finish with a pea-sized amount of shine serum or a few drops of lightweight hair oil, smoothed between your palms and pressed over the surface of your hair (avoid the roots). For maximum longevity, avoid touching your hair too much after styling and sleep on a silk pillowcase.
