A dermatologist has warned men against using shampoos formulated for women, citing a recent case where a young man exacerbated his hair loss to an alarming rate after using his girlfriend’s shampoo.
Dermatologist Chao Chao-ming (趙昭明) said the patient, a university student, had oily hair, with quite active scalp secretions.
After his girlfriend told him that his hair had a greasy odor, the man began using his girlfriend’s “two-in-one” shampoo and hair conditioner, Chao said.
After three months of using the shampoo, the man’s oily scalp became inflamed, irritated in part by his failure to thoroughly rinse his hair after shampooing, Chao said.
Chao said the man was losing more than 1,000 strands of hair a week and developed severe dandruff. When the man sought treatment, Chao found his scalp was reddened and inflamed.
The dermatologist found the type of shampoo the man was using contained a high level of conditioning materials, and although it was fragrant, the conditioning agents were building up and blocking his hair follicles.
“It was lucky that most of his hair follicles did not atrophy. If they had, he would have become permanently bald,” Chao said.
“A man’s oily skin secretions are about twice those of a woman. For those men who are active in sports, sweating and oily scalp secretions are even more pronounced. If they are not cleaned, then fatty deposits will build up and clog hair follicles,” he added.
Oily skin can be a prime environment for the growth of pityrosporum ovale, a bacteria that can cause dermatitis and other skin diseases, Chao said. If a bacterial infection takes hold, it could lead to inflammation of the scalp and result in loss of hair, he added.
“In some serious cases, it has led to permanent baldness,” he said.
Noting that men’s hair is on average shorter than that of women and also oilier, Chao said men should choose a shampoo with a greater cleansing effect.
Chao said clinical studies have found that up to 50 percent of problems with male hair loss were due to using the wrong type of shampoo.
Lin Shang-li (林上立), a skin disease specialist, advised men not to use “two-in-one” shampoos if they have an oily scalp, signs of male pattern baldness, inflammation of hair follicles or redness and swelling of the scalp.
A Taipei veterinarian is urging pet owners to avoid using insecticides around their homes, as their ingredients can be toxic to pets. Commercial-grade insecticides contain pyrethroids — organic compounds similar to natural pyrethrins, pesticides produced by flowers such as chrysanthemums — in quantities that are harmless to humans, but potentially fatal to cats and dogs, Asian Veterinary Specialist Referral Center veterinarian Chua Man-ling (蔡曼琳) said. Even in small quantities, pyrethroids are hazardous to cats, as they lack the metabolic enzymes needed to process them, Chua said. Cockroach sprays and ant traps are especially dangerous to pets as they contain boric acid, she
People should avoid eating too many zongzi (粽子, glutinous rice wrapped in bamboo leaves), as consuming several in one meal could cause indigestion, bloating, gastric acid reflux, heartburn and other stomach ailments, a doctor said on Saturday. Zongzi is a traditional delicacy for the Dragon Boat Festival, which was on Thursday. Citing a recent case as an example, Cathay General Hospital gastroenterology department head Chu Yu-ming (朱淯銘) said that a 58-year-old taxi driver surnamed Hsiao (蕭) ate meals at irregular hours due to his work and has been taking diabetes medicine for three years. Hsiao recently bought a bag of zongzi and ate
While stereotypically considered a household pest that simply will not die, Hung Ting-yang’s (洪鼎揚) experience with Archimandrita tesselata, commonly called the peppered roach, might change a person’s mind. The peppered roach originates in South America, is omnivorous and, as it is capable of growing to 7cm to 9cm long, is a giant compared with other roaches, which have an average length of about 4cm. The peppered roach goes through six separate chrysalis stages and takes nine months to reach full maturity. Mature roaches have wings, but cannot fly and can only glide. They have an average lifespan of three years. As his
The EU’s list of safe nations to which it would reopen borders next week does not include Taiwan, but the Ministry of Foreign Affairs yesterday said the list has not been finalized and some EU countries have highlighted the importance of “reciprocity.” The provisional list comprises Algeria, Andorra, Australia, Canada, Georgia, Japan, Monaco, Montenegro, Morocco, New Zealand, Rwanda, San Marino, Serbia, South Korea, Thailand, Tunisia, Uruguay and the Vatican, the New York Times reported on Friday. The EU said it would add China, considered one of the “acceptable countries,” if it also opens its borders to EU travelers, the newspaper reported. Backed by
