Polynucleotide hair treatment involves using polynucleotides—naturally occurring chains of nucleotides found in DNA—to stimulate hair growth and improve scalp health. These polynucleotides aid in cell regeneration, increase blood circulation, and reduce inflammation, which can help strengthen hair follicles and promote healthier, thicker hair. Often administered through microinjections, this treatment is popular for its regenerative effects on both the scalp and hair.
