The present invention relates to a composition which includes a polymer compound and a neutralizing agent and can be applied to damaged hair, wherein the compound included in the composition has unshared electron pairs and thus forms strong polar bonds with alpha-hydrogen in amino acids of the hair to which the compound is to be bonded, the composition has both a hard segment and a soft segment in the compound, and thus imparts multifunctionality, such as elasticity, repellency, and bulkiness, and collagen included in the composition attaches to damaged cell membrane complexes (CMC), thus enabling the damaged hair to recover. Further, oxygen included in the compound forms hydrogen bonds with moisture in the air to form a film having high antistatic properties and a large refractive index, and thus imparts gloss and deep-color effects.

A method for preparing non-free radical photo-crosslinked hydrogels includes: dissolving component A that is a polymer derivative modified with o-nitrobenzyl phototrigger in a biocompatible medium to obtain solution A; dissolving component B that is a polymer derivative containing hydrazide, hydroxylamine or primary amine in a biocompatible medium to obtain solution B; mixing solution A and solution B to obtain a precursor solution of hydrogel; under light irradiation, crosslinking aldehyde generated from the o-nitrobenzyl with the hydrazine, hydroxylamine or primary amine to obtain a hydrogel by forming hydrazone, oxime or schiff base, respectively. A kit for preparation and application of the hydrogel in tissue repair, beauty therapy, and cells, proteins or drugs carriers is also described. The method or kit can achieve in situ photo-gelling on tissue surface or in situ forming thin gel on wounds in clinical treatment of wounds.
