Absolutely, hair treatments can be very effective in controlling frizz. Professional salon treatments like keratin treatments, deep conditioning masks, and smoothing treatments are designed to nourish and tame unruly hair, reducing frizz and promoting smoother, sleeker strands. These treatments often include ingredients that help seal the hair cuticle, preventing moisture from entering and causing frizz. However, it's important to choose the right treatment for your hair type and consult with a licensed cosmetologist to ensure the best results. Additionally, incorporating proper hair care routines and using anti-frizz products at home will help maintain the treatment's effects and keep frizz at bay.
