Which treatment is commonly used to reduce frizz and smoothen hair?

A keratin treatment is specifically designed to reduce frizz and smoothen hair. This treatment involves applying a keratin-based formula to the hair, which then binds to the hair fibers, filling in gaps and smoothing out the cuticle. The heat used during the treatment helps to seal the keratin into the hair, providing a sleek and polished finish that lasts for weeks or even months.

Keratin is a naturally occurring protein in hair, and supplementation through this treatment aids in managing frizz, especially in humid conditions, and helps to improve the overall manageability and appearance of the hair. In contrast, while chemical relaxers also straighten hair, they can be more damaging and are different in purpose compared to keratin treatments. Deep conditioning masks primarily focus on moisturizing and repairing the hair rather than smoothing it out, and protein treatments strengthen the hair structure but do not have the same smoothing effect as a keratin treatment.
