Micro links, micro beads, micro rings, etc., do not require and heat, glue, or braids to be installed. This is a main reason micro links get looked at as one of the "safer" options for hair extensions. Removal is also quick and easy. Micro links tend to move more freely than keratin bonded or tape extensions. Many stylists and clients insist that this helps create blood flow by stimulating the scalp, and as a result, promotes hair growth. Though clients may think micro links are "safer" than other types of extensions, a number of factors here too, play a part.. Maintenance is required and MANDATORY (to ensure the integrity of your hair) every 4-6 weeks to re-position the hair extension accordingly near the root. This relieves tension so that there is no stress on the natural hair. Neglected maintenance appointments will result in the extension hanging lower on the hair shaft, causing stress on the natural hair. The links/beads will eventually become loose and begin to slide out, taking the extension, and in some cases, your hair with them. If regular maintenance is an issue for you to keep up with, then keratin bonds may be a better option for you. Micro links vary in types and sizes from: micro-cylinders, to links lined with silicone that protect the natural hair, to beads with interior ridges for a stronger grip, etc. If your hair is on the thin, finer side, Fairy Hair's Tinkerlinks may be beneficial for you as they are 1/10 the size of micro links/beads, and are extremely undetectable!
