Miss Shampoo (Chinese: 請問，還有哪裡需要加強) is a 2023 Taiwanese romantic comedy film directed and written by Giddens Ko. Marking his fourth feature, the film was adapted from Ko's 2010 novel Precisely Out of Control. It stars Vivian Sung, Daniel Hong, Kai Ko, Emerson Tsai, and Ying Wei-min, and centers on a triad boss (Hong) who falls in love with a hairstylist (Sung) after she saves him from an assassination attempt.

Originally pitched to adapt Precisely Out of Control into a feature film for 21st Century Fox, the project was scrapped due to the company's acquisition. Ko revived the project while producing Bad Education (2022), choosing to adapt only the fourth chapter of the novel with Machi Xcelsior Studios, following their collaboration on Till We Meet Again (2021). Principal photography took place from August to October 2022 in Taipei, Taoyuan City, and New Taipei City. The film partnered with the baseball team Rakuten Monkeys, filming scenes at the Rakuten Taoyuan Baseball Stadium and collaborating on the film's marketing campaign.

The film had its world premiere as the opening film of the 25th Taipei Film Festival on 22 June 2023, followed by a theatrical release in Taiwan on 26 July. It had an average box office performance and received mixed reviews from critics, who praised its humor, characters, and incorporation of gangster elements, but the gender stereotypes and sexist dialogues were subject to criticism. It also secured four nominations in the 60th Golden Horse Awards and seven nominations in the 26th Taipei Film Awards.
