<unk>  multiplication or<unk>  is a proposed technique to counter<unk>  loss. The technology to clone<unk>  is in its early stages. Experts previously assumed that in the case of complete baldness, follicles are completely absent from the scalp, so they cannot be regenerated. However, it was discovered that the follicles are not entirely absent, as there are stem cells in the bald scalp from which the follicles naturally arise. Abnormal behavior of these follicles is suggested to be the result of progenitor cell deficiency in these areas. The basic idea of<unk>  is that healthy follicle cells or dermal papillae can be extracted from the subject from areas that are not bald and are not suffering<unk>  loss. They can be multiplied (cloned) by various culturing methods and the new cells can be injected back in the bald scalp, where they would produce healthy<unk> . In 2015, initial trials for human<unk>  were successful in generating new follicles, but the<unk> s grew in various different directions, giving an unnatural look. As of 2019, scientists believe they may have solved this problem by using nearly microscopic 3D printed shafts to assist follicles growing upward through the scalp. This technique however is still in research phase and is not available for public or commercial use.
