The Brazilian blowout is a hair treatment that includes the application of a keratin solution to the hair, followed by sealing it in with a flat iron that employs high heat. This process is designed to eliminate frizz and enhance smoothness and shine in the hair. The heat from the flat iron activates the treatment, allowing the keratin to bond to the hair cuticles, resulting in a long-lasting straightening effect that can typically last for several weeks to months.

In contrast, deep conditioning treatments usually involve the application of a conditioner to hydrate and repair the hair but do not necessarily require heat for their efficacy, though using heat may enhance penetration. Hair oil treatments mainly focus on nourishing and moisturizing the hair and scalp, commonly applied without the use of heat. A scalp massage typically involves the use of fingers to stimulate the scalp and improve circulation and does not incorporate heat as part of its technique.

Thus, the unique characteristic of the Brazilian blowout is its reliance on heat during the treatment process, making it distinct from the other options listed.
