When girls complain to Gaza paediatrician Lobna al-Azaiza that they have no comb, she tells them to cut off their hair.
It's not just combs. Israel's blockade of the territory, ravaged by 10 months of war, means there is little or no shampoo, soap, period products or household cleaning materials.
Waste collection and sewage treatment have also collapsed, and it's easy to see why contagious diseases that thrive on overcrowding and lack of cleanliness - such as scabies or fungal infections - are on the rise.
"In the past period, the most common disease we have seen was skin rashes, skin diseases, which have many causes, including the overcrowding in the camps, the increased heat inside the tents, the sweating among children, and the lack of sufficient water for bathing," the doctor said.
Azaiza used to work at Kamal Adwan Hospital in Beit Lahia until Israeli tanks separated the north of the besieged enclave from the south.
Like most of Gaza's medics, she has adapted and continues to treat patients, walking to work past her own ruined house, demolished by an Israeli strike.
The tent clinic she set up with a small team began by treating children, but has by necessity become a practice for whole families, most of whom have also been ordered or bombed out of their homes, like the vast majority of Gaza's 2.3 million people.
Even the medication that is available is often unaffordable; a tube of simple burn ointment can now cost 200 shekels ($53).
International aid deliveries have been dramatically reduced since Israel seized control of the Rafah border crossing from Egypt, exacerbating a humanitarian crisis.
Israel denies responsibility for delays in getting urgent humanitarian aid in, saying that the U.N. and others are responsible for its distribution inside the enclave.
Azaiza has little doubt where the immediate solution lies:
"The border crossing must be opened so that we can bring in medications, as most of the current ones are ineffective: zero effect, there is no effect on the skin diseases that we see."
