Review: Helps control frizz - The BoldPlex 6 Leave-In Hair Serum is designed to help hydrate and protect dry, frizzy, or damaged hair. This lightweight leave-in treatment helps smooth the hair while adding moisture and shine without making it feel heavy or greasy. What I like about this product is that it helps control frizz and makes the hair feel softer and easier to manage. The formula is made to support hair strength and improve the overall appearance of damaged strands, which can be helpful for hair that has been affected by heat styling or coloring. Because it’s a leave-in treatment, it’s very easy to use. You only need a small amount applied to damp or dry hair to help improve smoothness and hydration.
