Willing to comply and tolerate all study procedures including: * Wearing the Lily device for the prescribed duration (device to be fitted before chemotherapy infusion, and worn during infusion and for at least two (2) hours and up to four (4) hours post infusion), * Complete all study related questionnaires. * Having photographs taken of the head at each visit. To note: * Participants who experience a hypersensitivity reaction to chemotherapy are allowed to continue in the study if the standard doses are maintained. * Participants on the chemotherapy plan KEYNOTE-522 are eligible for this study. * If a participant is prescribed a different chemotherapy treatment plan, they may be eligible for the study only if prior Sponsor approval is obtained. Exclusion Criteria: 1. Baseline alopecia defined as CTCAE v5.0 grade \> 0. 2. History of autoimmune disease associated with hair loss, e.g., alopecia areata, systemic lupus. 3. History of whole brain irradiation. 4. Recent chemotherapy (≤ 2 years), which caused hair loss. 5. Participants who are receiving or are planning to receive hormone replacement therapy or anti-estrogen therapy during the study, whereby the therapy in question has a known profile for causing hair loss. 6.

An existing history of scalp metastases or suspicion of presence of scalp metastasis. 14. Use of a cold cap, scalp cooling device or any other hair loss reduction device during the study. 15. Participants who, in the opinion of the investigator, will be inappropriate for inclusion into this study or will not comply with requirements of the study. 16. Participants who do not have the mental or physical ability to comply with time schedules and further study procedures. 17. Current participation in a clinical study or within the last 30 days prior to screening that may cause hair loss. 18. Participation in this study at an earlier stage.
