The helmet that can stop chemotherapy patients from losing their hair
Scientists have unveiled a groundbreaking approach, described as a "powerful double weapon", to combat Hair loss in cancer patients undergoing chemotherapy. The innovative method combines established scalp cooling with a novel lotion rich in antioxidants, similar to those found in red grapes. Research at Sheffield Hallam University identified 18C as the optimal scalp cooling temperature for preventing Hair follicle damage, noting that 26C offers insufficient protection. The study demonstrated that integrating topical antioxidants significantly enhances the protective effect of cooling, offering a solution for patients who may not fully respond to cooling alone. The team, led by Dr Nik Georgopoulos, hopes to trial this combined technique with cancer patients using the Paxman device, aiming to improve protection and accelerate Hair recovery.

'Milestone' technique could help cancer patients keep hair during chemotherapy
Researchers say they have found a "powerful double weapon" that could help cancer patients keep their hair during chemotherapy. The new method combines scalp cooling - where patients use cold caps to reduce hair loss from cancer drugs - with a lotion, comprised of antioxidants - some of which are found in red grapes. Hailed as a "milestone," researchers at Sheffield Hallam University also pinpointed the optimal temperature for scalp cooling to be most effective for keeping hair. Cold caps are already used by some cancer patients during chemotherapy to help minimise the amount of hair they lose. They work by restricting blood flow to the scalp, which reduces the amount of medication reaching the hair follicles. But the team at Sheffield Hallam University found that cooling the scalp to 18C (64.4F) can prevent hair follicle damage, while 26C may not be enough, and that topical antioxidants could "transform the ability of cooling to protect" against hair loss. Dr Nik Georgopoulos, an associate professor of cell biology and Transforming Lives fellow at Sheffield Hallam, told PA: "Chemotherapy drugs are drugs that kill rapidly dividing cancer cells, but they cannot discriminate between cancer cells and rapidly dividing normal cells in the body. "At the base of our hair follicles are these rapidly dividing cells, or keratinocytes, that constantly grow and they end up forming the actual hair." For the study, published in Frontiers of Pharmacology, hair follicles were isolated from the scalp and grown in the lab before being treated with chemotherapy to study the impact. "We show that they die," Dr Georgopoulos said. "The cells that are rapidly dividing and grow the hair, they will die because of the toxicity of chemotherapy. "But if you cool them, they are protected, and I don't mean just protected - prevented from dying. So if cooling is used while the hair follicles are grown in the lab, it can completely prevent the toxicity." The associate professor noted, however, that "there is a catch - you have to use the right temperature," but added that "our research has shown that cooling can slow down the cells, stops them from dividing - protection". He said that any issues with temperature could also be compensated with a topical location containing antioxidants like resveratrol, found in the likes of red grapes and peanuts, and dietary supplement N-Acetylcysteine. Dr Georgopoulos described the combination as a "powerful double weapon". Dr Georgopoulos has also been working with Huddersfield-based business Paxman Scalp Cooling, which created a device that circulates coolant through a specially designed cooling cap. The cooling cap is worn for half an hour before chemotherapy treatment commences, during treatment, and for up to 90 minutes after all the drugs have been given.

New technique hailed as ‘powerful double weapon' against chemo hair loss
Scientists have developed a new technique which they describe as a 'powerful double weapon' to prevent cancer patients losing their hair during chemotherapy. The method combines scalp cooling – where a patient wears a cold cap to help reduce hair loss from the damage caused by the cancer drugs – with a lotion comprising the same antioxidants found in the likes of red grapes. The study, which has been hailed as a 'milestone', also pinpointed the optimal temperature for scalp cooling to be most effective for keeping hair. Cold caps are used by some cancer patients during chemotherapy to help minimise the amount of hair they lose. The technique works by restricting blood flow to the scalp, which reduces the amount of medication reaching the hair follicles. Now, researchers at Sheffield Hallam University have found cooling the scalp to 18C can prevent hair follicle damage, while cooling to 26C may not provide enough protection to hair follicle cells. The team has also shown how combining topical antioxidants with cooling could 'transform the ability of cooling to protect' against hair loss. Dr Nik Georgopoulos, an associate professor of cell biology and Transforming Lives fellow at Sheffield Hallam, told the PA news agency that he views hair loss as the 'face of cancer'. 'The reason why people get hair loss is because, at the base of the hair follicles, there are these rapidly dividing cells that are actually feeling the toxicity of chemotherapy drugs,' he said. 'Chemotherapy drugs are drugs that kill rapidly dividing cancer cells, but they cannot discriminate between cancer cells and rapidly dividing normal cells in the body. 'At the base of our hair follicles are these rapidly dividing cells, or keratinocytes, that constantly grow and they end up forming the actual hair.' For the study, published in Frontiers of Pharmacology, hair follicles were isolated from the scalp and grown in the lab before being treated with chemotherapy to study the impact. 'We show that they die,' Dr Georgopoulos said. 'The cells that are rapidly dividing and grow the hair, they will die because of the toxicity of chemotherapy.

'So if cooling is used while the hair follicles are grown in the lab, it can completely prevent the toxicity. But there is a catch – you have to use the right temperature.' While an optimal temperature was highlighted in the study, researchers also combined cooling with the lotion as a potential target for patients who may not respond to the cold cap technique. It contained antioxidants like resveratrol, which is found in the likes of red grapes and peanuts, and N-Acetylcysteine, a dietary supplement. Dr Georgopoulos told PA: 'For some patients, cooling works, and for others it doesn't. Because some heads – I call them stubborn – they don't cool enough. 'By adding this topical product that delivers this antioxidant, we form a powerful double weapon that, based on our results in the lab, showed us it can transform the ability of cooling to protect.' Dr Georgopoulos added that the antioxidant lotion is not 'powerful enough' when used alone. 'The reason for that is cooling does multiple amazing things at the same time,' he said. 'What happens in the body when things go cold? You get the constriction of your blood vessels, they're narrowing down, less blood goes to the scalp, less drug. It isn't as simple as that. 'Our research has shown that cooling can slow down the cells, stops them from dividing – protection. 'It stops the chemotherapy drug going in – protection. It does multiple things at the same time as long as the cooling is optimal. 'If it isn't optimal, our approach is now allowing us to actually say 'it's OK, it's not an ideal scenario, but we compensate for it with our topical product'. Dr Georgopoulos has been working with Paxman Scalp Cooling for more than a decade. The Huddersfield-based business has created a device that circulates coolant through a specially designed cooling cap, worn by the patient. The cooling cap is worn for half an hour before chemotherapy treatment commences, during treatment, and for up to 90 minutes after all the drugs have been given. It is now hoped the new technique, combining scalp cooling with the antioxidants, can be trialled with cancer patients using the Paxman device, with researchers currently finalising the antioxidants that will be used in the topical product. Dr Georgopoulos said: 'Our ongoing work will ensure that efficacy is as high as possible with the belief that a topical agent will not only dramatically enhance the efficacy of scalp cooling in protecting from hair loss, but also significantly accelerates hair recovery post chemotherapy treatment.'
