The present invention pertains to: a double-stranded oligonucleotide construct having a structure in which a hydrophilic substance and a hydrophobic substance are conjugated by a simple covalent bond or a linker-mediated covalent bond at both ends of a DKK1-specific double-stranded oligonucleotide to efficiently deliver the double-stranded oligonucleotide into cells; a nanoparticle capable of being produced through self-assembly of the double-stranded oligonucleotide construct through a hydrophobic interaction in an aqueous solution; and a hair-loss-preventing and hair-growth-promoting composition containing the double-stranded oligonucleotide construct or the nanoparticle. A double-stranded oligonucleotide construct including a DKK1-specific double-stranded oligonucleotide, a nanoparticle, and a hair loss prevention or hair growth composition containing the double-stranded oligonucleotide construct or the nanoparticle as an active ingredient according to the present invention very efficiently suppress the expression of DKK1 without side effects and are remarkably effective for preventing hair loss and promoting hair growth, and can thus be very usefully used for a composition for preventing hair loss and promoting hair growth.
