VIRTUE conditioners contain Alpha Keratin 60ku®, which is the protein that makes up 90% of your hair, skin and nails. This ingredient smooths and resurfaces strands of damaged hair, which can help reduce frizz, repair split ends, increase hair thickness and promote hair vibrancy. Though each VIRTUE hair conditioner is designed to repair hair, we offer different formulas available for hair types with specific needs. When selecting a product for various curl types, consider the Curl Conditioner which is designed to nurture your curly hair. If your hair is fine, look for a lightweight conditioner that adds volume. For hair that tends to frizz, VIRTUE has a smoothing conditioner that will help to improve your hair's appearance with every shower.
