Mike prefers the clip-in or clamped-in methods for hair extensions to protect the integrity of the natural hair (fusion extensions can damage hair and require extensive maintenance). Extensions can be matched to your natural color, applied as contrast color, and can be highlighted. Extensions can be flat or curly and textured. Real human hair extensions are preferred because they are safer, and the client can curl or colorize as desired (acrylic extensions are a fire hazard and cannot be curled). A set of clip-in extensions can be applied and removed by the client for special occasions. Clamped-in extensions last for 5-6 weeks, and then require easy repeat maintenance to remove and reapply to keep up with natural hair growth. Clipped ad clamped extensions can be removed easily without damage to the hair.
