What type of hair treatment helps to close the hair cuticle?

1. Deep conditioning treatment

2. Chemical perm

3. Protein treatment

4. Conditioning treatment

The correct answer is: Conditioning treatment

The type of hair treatment that effectively helps to close the hair cuticle is a conditioning treatment. Conditioning treatments work by providing moisture and nourishment to the hair, which can lead to the smoothening and sealing of the cuticle layer. When the hair cuticle is closed, it becomes less porous and appears shinier, while also reducing the likelihood of damage and frizz. Conditioning treatments often contain ingredients that enhance the hair's ability to retain moisture and improve its overall texture and manageability. These treatments can include leave-in conditioners, deep conditioners, and even treatments designed for specific hair types. They primarily focus on enhancing the outer layer of the hair, which is critical for maintaining healthy hair. Other options, such as deep conditioning treatments, while also beneficial, typically focus on overall hydration and penetrating deeper into the hair shaft rather than solely closing the cuticle. Chemical perms alter the hair structure for styling purposes rather than promoting cuticle closure. Protein treatments are geared toward strengthening the hair by repairing damaged areas but may not directly impact the cuticle's state in the same way that a conditioning treatment would.
