Some people become particularly distressed because of their frequent hair loss. In this case, they are always worried about becoming bald. Therefore, they have to choose shampoos that will not cause more hair loss. Most of these shampoos are mild and non-irritating, so as not to cause too much irritation to their scalp. In addition, some shampoos with conditioning functions should be used for cleaning. Shampoo can be roughly divided into five categories[2]: (1) Transparent shampoo, which was the earliest to appear, has a simple formula and is mainly used for cleansing. (2) Pearlescent shampoo: Pearlescent shampoo is made by adding pearlescent agent to transparent shampoo. This product has no requirement for transparency. Currently, there are two ways to add pearlescent agent: one is to use pearlescent agent directly, and the other is to use pearlescent slurry. (3) Conditioning shampoo. This product is currently the most popular type of shampoo. The familiar two-in-one shampoo is one of them. It combines shampooing and hair care into one, completing the process at one time. Conditioning shampoo is a regular shampoo with various conditioners added to achieve the desired effect. (4) Anti-dandruff shampoo. Dandruff is caused by scalp dysfunction, such as bacterial growth, seborrheic dermatitis, abnormal proliferation of glial cells, etc. Excessive dandruff will breed more bacteria and fungi, causing symptoms such as scalp itching. Therefore, some active ingredients with antibacterial and bactericidal effects are often added to shampoos to effectively control dandruff. (5) Sunscreen shampoo. When hair is exposed to ultraviolet radiation for a long time, some photochemical reactions will occur, which have a great impact on the physical and chemical properties of the hair. Therefore, some sunscreen is often added to shampoo to properly prevent ultraviolet damage to the hair. (1) Do not shampoo too often as this will damage your hair and scalp. It is recommended that you shampoo no more than twice a day. (2) Dry immediately after washing to prevent the breeding of pathogenic microorganisms. (3) It is not recommended to wash or care for any damaged or wounded scalp skin. (4) People who are prone to allergies can apply a small amount behind the ear as a test. If redness, swelling, itching or other adverse reactions occur, stop using the product. If the condition is serious, seek medical attention immediately. |
