In the study carried out by TMDU's department of stem cell biology, mice that had been given a high-fat diet (HFD) were more subject to inflammatory (炎症的) responses in the body which,  5  , blocked follicle regeneration, leading to hair loss. What was surprising was that the  6   in the hair follicles could happen in as little as four days spent on a high-fat diet and that the problem seemed to be worse in older mice.

"High-fat diet feeding makes hair  7  faster by reducing HFSCs, especially in old mice," explains Hironobu Morinaga, the study's lead author. "We compared the gene expression in HFSCs between HFD-fed mice and standard diet-fed mice and   8  the fate of those HFSCs after their activation."

It's not just the  9   content of your food that can damage your hair as what you consume can really affect how your hair grows and even whether men will keep it, as Dr Alia Ahmed, who specializes in the study of skin, explains.  10   shortages are often the root cause of many hair problems, adds Dr Ahmed.
