Cold weather and the thought of being cold washing one’s hair at home drives many people to the salons to have their hair washed. Besides being wary of other people using excessive force when washing your hair, the detergency of the shampoo might also be too strong, possibly causing hair-related allergies or even hair loss.
When going to the salon to have your hair washed, many people ask salon assistants to scratch their scalp harder while washing their hair. The assistants also generously apply thick layers of shampoo directly to the scalp and then add water and scratch until foam appears. Dermatologists warn that such actions are not good for the scalp.
Dermatologist Chao Chao-ming says that he recently had a 28-year-old pink-collar worker patient who on average was going to salons once every three days to have her hair washed. After a period, her scalp became dry and itchy and she started suffering hair loss. She had no other option but to see a dermatologist. The doctor recommended that she only wash her hair at home and her condition eventually improved.

Chao says that using excessive force while washing your hair can damage the scalp and cause inflammation. Putting a plethora of shampoo directly on the scalp is not ideal either, particularly if the shampoo is substandard, which means that it probably contains a lot of petrochemical surfactants, synthetic fragrances and preservatives that can irritate the skin and cause allergic reactions, Chao says.
Regarding how to go about selecting the right hair products, Chao says that when choosing a shampoo, one should avoid products that excessively stimulate the scalp, and be sure to look at the label showing the ingredients to avoid products with too many chemicals, surfactants, fragrances or preservatives.

天氣冷、很多人想到洗頭就覺得更冷,乾脆上美容院洗頭髮。不過讓別人洗頭,除了要注意不要過度用力搔抓,有時候洗髮精的洗淨力太強,也可能造成頭髮過敏,甚至落髮。
上美容院洗頭時,不少人會要求美容院的助理洗頭時用力搔抓。助理們在洗頭時,甚至會直接把濃稠的洗髮精大量倒在頭皮上,然後再加水抓起泡。但皮膚科醫師表示,這些動作對頭皮一點都不友善!
皮膚科醫師趙昭明指出,有一名二十八歲的長髮粉領族,平均每三天就上一次美容院洗髮。一段時間後,不僅頭皮乾澀、發癢;後來還開始掉頭髮。她只好到皮膚科求診,在醫師建議下,換成自己在家洗頭,症狀果然好轉。
趙昭明指出,過度用力洗頭可能造成頭皮傷害、發炎,直接把洗髮精大量倒在頭皮也不理想,因為用的洗髮精如果不夠好,裡面有多種石化的介面活性劑,又添加比較多的香精、防腐劑等,除了太過刺激,相對造成過敏等症狀的風險也較高。
至於在家洗頭該如何選擇適合的髮妝品呢?趙昭明指出,在選擇洗髮精時,如何避免過度刺激頭皮,可以看成分標籤,避開內含化學成分太多、介面活性劑種類太多,或是香精、防腐劑等較多的產品。

A few new policies take effect this month, with the following most likely to affect our daily life. Nationwide ban on disposable plastic cups in beverage shops According to the Ministry of Environment’s “Parties Subject to and Means for Single-use Takeaway Beverage Cups Restrictions” implemented on July 1, 2022, beverage shops are required to offer a NT$5 discount for customers who bring their own cups, and all local governments will be required to devise schedules to phase out single-use beverage cups. With the nationwide ban taking effect from this month, it is expected that the number of disposable plastic cups will be
Foxes are known for being cunning and resourceful, but a study suggests another surprising talent. Research from the Czech Republic indicates these creatures may use the Earth’s magnetic field when hunting. The study, led by Jaroslav ?erveny, tracked wild red foxes for over two years, recording nearly 600 hunting leaps by 84 foxes. Researchers found the animals predominantly jumped in a northeasterly direction, regardless of the time of day, season, or weather conditions. This preferred leaping direction resulted in a much higher kill rate, with foxes finding success on 73 percent of their northeasterly pounces on their prey. The results prompted
Earthquakes are among the most terrifying natural disasters, generating massive tremors and destructive forces as Earth’s crust shudders. These tremors not only lead to the collapse of buildings but can also trigger secondary disasters, such as tsunamis and fires. However, we can mitigate the impact on lives and property by mastering earthquake response techniques. The DCH three-step strategy, recommended by the Centers for Disease Control and Prevention (CDC), is crucial during an earthquake. “D” stands for “drop.” You should immediately drop to the ground, using your hands and knees to support yourself. This position prevents you from falling and
Continued from yesterday(延續自昨日) https://www.taipeitimes.com/News/lang The potential use of magnetism to improve hunting ability is not the only surprising aspect of the fox’s complex behavior. The furry creatures are also known for their wide range of vocal expressions. They can produce a surprising range of sounds — up to 40 in total. The most well-known fox vocalization is the scream-like howl, but they also use barks, chatters, and whines to communicate with each other. These sounds are used to defend territory, attract mates, and care for their young. Besides the variety of sounds foxes utter and their possible use of the
