    TLDR RK81 can help promote hair growth.
    The study focuses on the rational design of water-soluble recombinant keratins (RKs) K31 and K81 using QTY Code methodology to overcome the limitations of traditional keratin extracts and pure recombinant keratins. These RKs were used to create microneedles to investigate their effect on hair growth. The results showed that more than 40% of hair follicles (HFs) responded positively to RK81, indicating its potential for promoting hair growth.
