Carrot oil can help hair to grow faster and thicker. People who are looking to keep their hair long and avoid split ends may find that carrot oil helps. Conditioning the hair with carrot oil is also said to improve its texture, making it shinier, smoother, and softer to the touch. By boosting blood circulation to the scalp, carrot oil could also serve to keep your hair healthier from root to tip.
As with any topical product or supplement, carrot oil carries the risk of allergic reaction. Before applying carrot oil to your hair, do a patch test on a small area. Always dilute carrot oil with a carrier oil before application.
