Hong Kong’s weather is difficult to adapt to, with tropical summers and cold winters. When seasons change, the skin is affected by the weather, becoming prone to sensitivity. The scalp has the most pores and therefore is the most fragile part of the skin, often becoming itchy and irritated as the seasons change. To prevent irritation from the changing seasons, it’s important to take good care of the skin.
Spring - from dry to humid
Spring is a season filled with life, but with Hong Kong’s humid weather and buildings filling up the streets, the air can feel hot and suffocating. This kind of environment can become a breeding ground for all sorts of bacteria, and it takes a toll on the skin as well.
Some experts believe that in weather like spring, microorganisms, specifically fungus, become particularly active, causing skin problems like eczema and ringworm. When fungus grows on the scalp, the skin may become inflamed and itchy. If the skin is scratched, it can lead to peeling and even wounds that take a long time to heal. To avoid scalp sensitivity, it’s important to change bedsheets often and keep living environments clean to prevent fungus growth. When washing hair, avoid using water that is too hot as it will strip the scalp of natural oils and cause further irritation.
Summer - rising temperatures
Hong Kong is infamous for its hot and humid summers, temperatures that cause excess sebum production, and clogged pores. In weather like this, washing hair daily is a must to avoid the buildup of oil and dirt. Without daily hair washing, bacteria is easily accumulated on the scalp. Certain hair products are effective in removing bacteria and fungus from the scalp, especially products containing selenium, a mineral known to destroy a specific type of fungus called Malassezia. Other ingredients like yarrow also work as an antiseptic and antiperspirant, perfect for summer weather.
Autumn - transition to dry weather
Autumn is the favorite season of many people, with cooler and dryer weather that feels the most comfortable. However, it may take some time for the skin to adjust from the previously hot and humid environment to this dryer, cold weather. During this time, it is common for the scalp to be dry and peeling, so moisturizing the scalp is the main focus. Using deep cleaning products can be too harsh, causing further dryness and irritation.
When it comes to hair care ingredients, products containing iron will be beneficial to address scalp problems, as iron boosts circulation within the body. Better circulation means that more oxygen is carried to the scalp, enabling follicles to produce healthier, stronger hair. Rosemary is another effective ingredient to promote circulation, as well as soothing the scalp of irritation and discomfort caused by autumn’s dry weather.
Winter - irritation caused by dryness
Lately, Hong Kong’s winters haven’t been as cold as it has been in the past, but the dry weather still presents a problem for many people with sensitive skin. Blood circulation and metabolism slow down as the temperature lowers, meaning that less sebum is produced by the skin. The lack of natural oils to protect the scalp makes it easier to cause tears and wounds in the skin if it is scratched. For those with dandruff, it is crucial to avoid using water that is too hot to wash the hair, and to not wash the hair more than once a day. Using a conditioner or hair oil can be helpful, but it is important to read the ingredients beforehand and to make sure not to use the products on the scalp to avoid clogged pores.
