Hydrogel coating was explored to modulate the shape of keratin hair fibre. The motivation was the development of an eco-friendly methodology with nontoxic chemicals to modulate keratin fibre. Polymeric hydrogel of acrylic acid and N-N-dimethylacrylamide was prepared by free-radical polymerization in aqueous solution, using nano-alumina particles as crosslinker and potassium persulfate as an initiator. Physico-chemical properties of the hydrogel was investigated by Fourier transformer infrared spectrum (FTIR), thermal analysis and swelling ratio behaviour. After hydrogel coating, morphological modification was observed from straight to curly hair effect. The influence of hydrogel coating on hair fibre was evaluated by perming efficiency supported by X-ray diffraction and morphological characterization (SEM and AFM). The durability of hydrogel coating was tested until four wash processes maintaining around 65% the new configuration of the hair fibre.
