A mayonnaise hair treatment is an effective hair conditioner that can help restore vitality and sheen to your hair. It contains oil, vinegar and egg yolk, which are all natural conditioners and cleansers that help in adding luster and shine to the hair. Mayonnaise is especially recommended for dry and overly damaged hair.
Simply apply a liberal coat of mayonnaise on your hair, making sure to cover strands from the root to the tips. Leave on for at least a half hour, then wash normally.
