Do you worry about sticky scalp and odor in the summer when you tend to sweat?
You may think, “I need to take a shower and freshen up!” but it is difficult to do so on the way to work or when you are out and about.
In such cases, we recommend “dry shampoo” to refresh scalp discomfort without using water or hot water.
Although it gives the impression of being used for nursing care or in times of disaster, it is actually a convenient item that can be used on a daily basis.
Most products are marketed by manufacturers for women, but they are also recommended for men who are concerned about sweat and sebum.
Scalp Odor is A Concern in Summer
In summer, the three causes of strong scalp odor-sweat, sebum, and bacteria-often come together.
In particular, men are said to secrete two to three times as much sebum and sweat as women, making them more prone to odor.
First of all, the scalp has many sweat glands, which secrete sweat, and the number of sweat glands is second only to the palms of the hands and soles of the feet.
In addition, the scalp has many sebaceous glands, which secrete about twice as much sebum as the amount of sebum in the T-zone.
When scalp sweat and sebum mix and oxidize, fatty acids are produced, causing odor and stickiness.
In addition, beware of hot and humid environments.
The scalp, where hair is densely packed, is prone to steam and bacteria can easily multiply.
Bacteria breed by feeding on excess sebum and dandruff, causing unpleasant odors.
Such unpleasant smells and stickiness can be eliminated by shampooing, but it is difficult to do so when you are out and about.
What is Dry Shampoo
Dry shampoo is a hair care product that refreshes the scalp and reduces hair odor and stickiness without rinsing with water or hot water.
Although it has a strong image as a disaster prevention product to be used in times of emergency, such as during disasters when water is not available, it can be used in many everyday situations, such as when you are sweating while commuting to work or outside, after exercising, or when your hair smells of cigarettes.
Using dry shampoo is simple.
For the mainstream spray or mist type, simply apply it evenly to hair and scalp, massage it in lightly, and wipe it off with a dry towel.
This is a shortcut item that allows you to take care of your hair quickly even when you are short on time.
Although it is a convenient item that saves you the trouble of drying your hair, it does not wash out dirt from your scalp as well as regular shampoo.
It is recommended that you use it only as a “temporary care” item, such as when you are out of the house or in the event of a disaster.
How Dry Shampoo Works
Dry shampoo is a shampoo that does not need to be rinsed off. Its main ingredient is ethanol, which is used for its deodorizing and disinfecting effect, and alcohol and peppermint are used as ingredients to give a refreshing feeling.
Some products also use plant-derived powder or silica powder as the main ingredient, which is a sebum adsorbing ingredient. Silica powder is one of the most popular ingredients. Silica is an ingredient with high chemical stability and low optical refractive index among inorganic oxides. Therefore, not only can it be expected to prevent oxidation of oily ingredients and suppress photocatalytic activity that causes discoloration of active ingredients, but it is also considered to be an ingredient that can easily produce synergistic effects such as improved feel and durability.
The above ingredients work to alleviate stickiness and odor by floating and removing excess sebum and dirt from the scalp. The alcohol and sebum adsorbing ingredients also work to provide a refreshing feeling after shampooing without having to rinse it off.
Unlike regular shampoos, dry shampoos are generally used as a supplemental shampoo when it is not possible to wash hair.

Things to Note When Using Dry Shampoo
Dry shampoo is a convenient item that is portable and has the advantage of refreshing the scalp without the use of water, but remember that it is a simple product.
Naturally, compared to washing hair and scalp with ordinary shampoo using hot water in a bath, the rate of sebum removal from the scalp is lower. Since there is no process of rinsing off the dirt, dirt tends to remain on the scalp.
In addition, dry shampoos contain ethanol (an alcohol ingredient) to remove sebum stains that cause stickiness and odor. While this ingredient is expected to have a degreasing effect, there is a concern that it may tend to dry out the scalp. People with sensitive skin should be careful not to use it too often, as it can cause scalp irritation.
