Hair serum is a liquid-based treatment usually formulated using silicones that provide a protective layer over the hair fibre, assisting in smoothing frizz. This smooth layer then reflects the light, which is how serum gives your hair a shiny, not greasy, finish. A light, non-greasy formula that will make your hair soft & shiny.
For best results use on damp hair. Take 1-2 drops in your palm. Rub both hands together to spread it. Apply from the midsection of your hair and work it downwards to the tip.
