If you want longer, healthier-looking hair, using a hair mask can help you achieve that. The best hair masks for hair growth often contain ingredients, such as argan, jojoba, and other natural oils, that help nourish and strengthen hair follicles. Fair warning: Since diet and genetics play an important role in your head of hair, a hair mask won't necessarily speed up growth, but they do help prevent hair breakage and can improve the length and strength of your hair over time. That's why hair masks are so popular amongst those trying to boost their hair growth.
According to Jesse German, a celebrity hair stylist at Martinez-Samuel Salon in West Hollywood, CA: "The benefits of using a hair mask if you’re trying to grow your hair is that you are infusing the hair with moisture and proteins designed to improve the integrity and strength of the hair from the inside out. Healthier hair means less split ends, eliminating split ends means less to trim off at each haircut, thus the hair is fuller, stronger, smoother and longer.”
Word to the wise: Although hair masks can be a beneficial part of your hair regime, you don't want to overdo it and apply them too often, however. Experts generally recommend using a mask once a week.
