What is the difference of hot oil and hair spa?

Hot oil treatment involves applying warm oil to the hair and scalp to nourish and hydrate, often using natural oils like coconut or olive oil. A hair spa, on the other hand, is a more comprehensive treatment that typically includes a combination of massage, shampooing, conditioning, and sometimes specialized products to promote relaxation and improve hair health. While hot oil treatments focus primarily on hydration, hair spas offer a holistic approach to hair care and overall relaxation.
