Attaching hair to a polymer doll is a detailed craft requiring patience and precision. Begin by selecting the right type of hair—options include synthetic, mohair, or real human hair, based on the desired look. If using wefts, start at the base of the doll's head, applying a thin layer of strong, clear-drying glue, such as E6000 or a specific doll-making glue. Gently press the edge of the hair weft into the glue, working your way up to create layers. For rooted hair, tools like a rooting needle or felting needle are necessary. Create small holes in the doll's scalp using the needle, then insert small bunches of hair, securing them inside with glue. Whichever method you choose, plan the hairstyle in advance to ensure a natural look. Allow ample drying time before styling. This process blends artistry with craftsmanship, allowing for custom stylization.

Amino acids are organic compounds that serve as the building blocks of proteins. They play crucial roles in various biological processes. Once proteins are synthesized in the body through the linkage of amino acids in specific sequences, these proteins contribute to muscle growth, repair tissues, and produce enzymes and hormones. Additionally, certain amino acids act as neurotransmitters or their precursors, regulating mood and vital bodily functions. Some amino acids also participate in the immune response and help in nutrient absorption and energy production within cells. Therefore, amino acids are fundamental to maintaining life, supporting growth, and ensuring the proper functioning of the body.
