i have always wondered does Chihiro lose her memories about the spirit world when she returns to the real world

I dont think so, why would Chihiro look back again when she went out the tunnel and the first time she went there, she was so afraid and dependent but when she got out, when her papa sinabi that a new school and a new tahanan may be tough but Chihiro replied i think i can handle it as a sign that she became madami bravo and strong through the experiences she had in the spirit world... she remember everything especially Haku XD

It is mentioned sa pamamagitan ng director and creator Hayao Miyazaki that Chihiro has 'lost' all her memories of the Spirit World following her exiting of the tunnel. However according to Haku's promise, he and Chihiro will meet again someday. This may or may not be referring to Chihiro's death and transformation into a spirit. However, Zeniba's quote, "memories are never forgotten, they are just difficult to recall" suggests that Chihiro will eventually remember her experiences at the Bathhouse. Regardless, the fate of Chihiro and Haku's relationship remains unknown and up to audience interpretation.
