Abstract: The invention relates to a method for producing an osteotropic bone replacement material from a starting material which substantially has portlandite, calcium oxide, aragonite; calcite and/or apatite. The starting material is introduced into an autoclave with a strontium, fluorine and/or gallium source, wherein when using a starting material which substantially has portlandite, calcium oxide, aragonite; calcite a phosphate source is introduced. In addition, H2O is added into the autoclave as part of a solvent and the pH value in the autoclave is set to a range above 7. Afterwards, the closed and filled autoclave is heated for at least 1 hour and then cooled. The osteotropic bone replacement material thus developed is subsequently cleaned from residues of the phosphorus, strontium, fluorine and/or gallium source. Furthermore, the invention relates to an osteotropic bone replacement material which substantially consists of apatite and in which strontium ions are incorporated into the crystal lattice.

Abstract: Hair extensions are disclosed that include a weft and at least a single micro-cylinder, wherein the weft comprises a plurality of hair, a skin weft and at least a single i-tip. Hair extensions may also include a weft and at least a single micro-cylinder, wherein the weft comprises a plurality of hair, a skin weft and at least a single i-tip; wherein a top section of the plurality of hair is bonded together to form the skin weft and the at least single i-tip. Methods of attaching a hair extension, wherein the hair extension comprises a micro-cylinder, a plurality of hair, a skin weft and at least a single i-tip are also disclosed herein that include bonding the plurality of hair to form the skin weft and the at least a single i-tip; threading a segment of natural hair through the micro-cylinder; inserting the i-tip into the micro-cylinder; and crimping the micro-cylinder to secure the i-tip.
