Main Highlights

ABOUT VO5: Alberto VO5 began as a conditioning hairdressing created by a chemist and a hairdresser, in Culver City, California. VO5 stands for 5 Vitamin Oils (Sunflower Seed Oil, Mango Seed Oil, Sweet Almond Oil, Rosemary Leaf Oil, Chamomile Flower Oil) and was originally used to offset the harsh conditions of Hollywood sound stages. All of their products combine the five essential vitamins to keep your hair healthy and strong. Vitamins Include: Vitamin B3, C, E, B5 & Biotin.
HAIR SERUM: Although many of us enjoy the sleek end result achieved with a hairdryer or straightener, or the springy curls and waves crafted with the twist of a curling iron, the damage that heat inflicts on our hair is many times an afterthought. Fortunately, using the VO5 Heat Protect Hair Serum can provide a safeguard for hair by acting as a barrier between intense heat and fragile strands and shielding hair from temperatures up to 230°C.
HAIR PROTECTION: This heat-protectant serum helps protect coarse, dry hair against the damage caused by heat-styling tools and tames frizz and flyaways, leaving your hair beautifully smooth and shiny.
HOW TO USE: Simply rub the serum through the palm of your hands and then, using 2 fingers, gently apply it to the strands using a pressing motion anywhere you want to control frizz.
EVERYDAY STYLING: VO5 is here for your everyday styling wants and needs! As the UK’s #1 styling brand, VO5 has a part to play to give you a better hair day, every day. If you liked VO5 Heat Protection Hair Serum, be sure to check out the other VO5 hair styling products in the full range like our Hair Fibre, Hair Paste or Hair Putty to remix your style and experiment with your hair even further
