According to a 2023 report by the Korea Institute of Science and Information Technology, the global hair loss care market is expected to reach 27 trillion won in 2025, and the domestic market is expected to reach 499 billion won.

The share of shampoos in hair loss care in Korea increased from 31.2% in 2015 to 42.7% in 2020, and the Korean Hair Loss Association announced the results of a survey that showed that among 390 people with hair loss experience, they intended to treat hair loss. There is the use of shampoo or ampoule.

Shampoo is a type of detergent used to wash hair. The purpose of shampoo is to keep the scalp and hair clean. The main ingredients of shampoo are 50% water and 30% surfactant, and the remaining 20% ​​is made up of nutrients, moisturizing substances, and fragrance. The characteristics of shampoos, which are classified in semi-drugs, functional cosmetics, and cosmetics, are determined by differences in the classification of nutritional components.

Shampoo is growing. The number of people hoping to grow hair and reduce hair loss through shampooing is increasing, and lifestyle health companies and cosmetics manufacturers are racing to launch new shampoos together. associated with hair loss. That is why there is a demand for shampoos related to hair loss.

However, hair loss shampoo cannot turn a bald spot into a forest of lush hair. The Ministry of Food and Drug Safety considers shampoo to be a cleanser that contains ingredients that are good for hair, not a hair loss treatment. The Ministry of Food and Drug Safety does not recognize the effect of hair treatment shampoos, whether they are semi-drugs or functional cosmetics, in a completely different situation than what the manufacturers of hair loss shampoos such as increased hair density, improved hair elasticity, and increased crown hair volume.

In fact, a functional shampoo can be helpful in improving the environment of the hair. Shampoos containing active ingredients for hair growth can produce positive results in cell tests.

Active shampoos that are sold are made up of several ingredients that are good for hair, such as biotin, niacinamide, dexpanthenol, menthol, zinc pyrithione solution, nicotinic acid amide, salicylic acid, zinc pyrithione, and zinc pyrithione solution. Menthol, salicylic acid, and dexpanthenol are ingredients notified by the Ministry of Food and Drug Safety that help reduce the symptoms of hair loss. Dexpanthenol, vitamin B5, is an essential ingredient in the production of collagen, which is involved in hair formation, and the lack of biotin, vitamin B7, causes hair thinning. Menthol, zinc pyrithione, and zinc pyrithione are known to have anti-inflammatory and antifungal properties, while minerals, peppermint, ceramide, silicon, and ginkgo leaf extract are known to have nourishing, moisturizing, and enveloping effects.

In fact, these ingredients are positive for stopping scalp inflammation, removing dead skin cells from the scalp, cleansing hair, and improving hair nutrition. Dermatitis, dead skin cells, and scalp itchiness can be improved by washing the skin and hair with the active ingredients of the shampoo. Environmental hair loss that occurs as a result of a decline in scalp health, such as seborrheic dermatitis and lack of hair nutrition, can also be expected. The nourishing ingredients in the shampoo have a temporary effect in delaying telogen hair loss.

However, shampoo cannot be expected to treat or improve androgenic hair loss, which accounts for the majority of hair loss. DHT is the key to treating androgenic hair loss, which is influenced by genes. The main ingredients in shampoos, such as niacinamide and biotin, cannot block DHT. The active ingredients in commercial shampoos only stay on the scalp for a short time while you wash your hair. The active ingredients do not penetrate the skin and enter the hair follicles, but are washed away with water. This is why the production of DHT in hair follicles cannot be suppressed.

In addition, sulfates added to some shampoos are useful in removing oil from the scalp, but they can irritate the scalp, aggravate seborrheic dermatitis, and cause itching, dandruff, and cause dry scalp. In this case, the health of the hair decreases and the risk of hair loss increases.

Due to the above, a functional shampoo can help improve the scalp environment. This is a positive factor for environmental hair loss, but has no effect on hair loss caused by genetics. Instead, products with added sulfates can sometimes worsen the skin environment. Therefore, it is unreasonable to expect the effects of hair loss treatment by using shampoo, and expecting hair loss treatment or improvement with shampoo would be hopeless at the moment.
