Dandruff
Dandruff is the excessive flaking of dead skin that forms on the scalp. As it is normal for skin cells to die and flake off, a small amount of flaking is normal and in fact quite common. Some people, however, either chronically or as a result of certain triggers, experience an unusually large amount of flaking, which can be not only a visual nuisance, but is also often accompanied by redness and irritation.

Oct. 5, 2025 — Researchers have uncovered how a protein called MRAP2 acts as a key regulator of hunger. It helps move the appetite receptor MC4R to the cell’s surface, allowing it to send stronger “stop eating” signals. The discovery offers new hope for ...
Oct. 4, 2025 — A massive new study combining observational and genetic data overturns the long-held belief that light drinking protects the brain. Researchers found that dementia risk rises in direct proportion to alcohol consumption, with no safe level ...
Oct. 4, 2025 — The STEP UP trials revealed that a 7.2 mg dose of semaglutide led to greater weight loss than the currently approved 2.4 mg dose. Nearly half of participants lost 20% or more of their body weight, ...
Oct. 4, 2025 — Researchers uncovered a key cellular regulator, PP2A-B55alpha, that controls both the cleanup of damaged mitochondria and the creation of new ones. In Parkinson’s disease models, reducing this regulator improved symptoms and mitochondrial health. ...
Oct. 4, 2025 — Scientists discovered that vitamin D2 supplements can lower levels of vitamin D3, the form the body uses most effectively. Unlike D2, vitamin D3 enhances the immune system’s first line of defense against infections. This raises questions about ...
Oct. 4, 2025 — A Weill Cornell Medicine team has found that triple-negative breast cancer depends on the enzyme EZH2 to spread. By silencing key genes, EZH2 drives chaotic cell divisions and fuels metastasis. Blocking EZH2 restored stability and prevented cancer ...
Oct. 4, 2025 — Metabolic dysfunction-associated steatotic liver disease (MASLD) affects over a third of the global population and is linked to serious health problems. A new study has revealed that high blood pressure, diabetes, and low HDL cholesterol are the ...
Oct. 4, 2025 — A Scandinavian clinical trial has revealed that low-dose aspirin can halve the risk of colon and rectal cancer recurrence in patients with specific genetic mutations. The research, involving over 3,500 patients, is the first randomized study to ...
Oct. 3, 2025 — New research from Houston Methodist reveals how obesity may directly drive Alzheimer’s disease. Scientists discovered that tiny messengers released by fat tissue, called extracellular vesicles, can carry harmful signals that accelerate the buildup ...
Oct. 3, 2025 — A massive nationwide study has linked long-term exposure to the industrial chemical trichloroethylene (TCE) with a higher risk of Parkinson’s disease in older adults. Researchers examined over 1.1 million people, finding that those living in areas ...
Oct. 3, 2025 — Ohio State researchers have discovered that exhausted T cells collapse under the weight of misfolded proteins, activating a destructive stress response called TexPSR. Unlike normal stress systems, TexPSR accelerates protein production, flooding the ...
Oct. 3, 2025 — Flu detection could soon be as simple as chewing gum. Scientists have created a molecular sensor that releases a thyme-like flavor when it encounters influenza, offering a low-tech, taste-based alternative to nasal swabs. Unlike current tests that ...
