Can I not wash my hair after using the no-wash hair spray? what do you think?

This kind of thing my girlfriend uses is called "waterless shampoo spray", which is also called no-wash spray. It is known as "hair is clean without washing" and one of "mild and non-irritating". It is very suitable for closed environment and inconvenient to wash hair. "People use" a cosmetic ". Isn't this amazing? Let's look at the ingredients first. From the filing materials of the US Food and Drug Administration, we found that there are several kinds on the market. We can see that the combination of different products is similar. They all contain fixed propellant absorbent, antistatic agent, hair conditioner and some products will add some plant extracts as skin conditioners to enhance the sense of use. From the perspective of product structure, the ingredients used in these products are relatively simple.

Moreover, various ingredients are not very irritating to skin and hair, so it is really a cosmetic that can be used with confidence. When washing hair, we use the surfactant in the shampoo to "bind" the dirt in the hair and wash away the foam with flowing water to achieve the purpose of cleaning. When we encounter some emergency situations, such as temporary needs, when guests don't wash their hair, they need to enter an "emergency state", and the cleaning mechanism of spray is different. It uses propellant to spray functional components from the water tank, absorbs the oil on the hair through absorbent, and adds some antistatic agents, hair conditioners and skin conditioners to achieve the purpose of hair care and refreshing. In essence, no-wash spray is not "cleaning", but "temporarily removing grease from the hair surface", so the statement that "you don't need to wash your hair after use" may mislead consumers.

It should be noted that the use of leave-alone spray can not completely replace shampoo, but only applies to emergencies, rather than "no need to wash your hair with shampoo", because leave-alone spray can only absorb the oil on your hair and make it look less greasy. In fact, it doesn't work in cleaning. It can only temporarily solve the problem of greasy hair, and dandruff and itching can't be alleviated. If you rely too much on leave-alone spray, please reduce the frequency of washing your hair. As a result, the scalp can not be cleaned in time, so that the grease and dust on the scalp continue to accumulate, aggravating dandruff, itching, scalp inflammation and other problems, affecting hair health. Excessive use may also destroy the balance of hair oil secretion and make hair dry.

In addition, some flavoring agents, preservatives, thickeners and other ingredients added to the product may improve its efficacy, but it may also bring allergic risks. People with hair loss and sensitive scalp should pay more attention. Please make sure your hair is dry before use. If water remains in the hair, it will affect the use effect. When using the no-wash spray, shake it well first, and then spray it at a distance of about 15cm from the hair. Don't be too big at a time. When using a pointed comb, divide the hair into 5 cm areas, and spray and cover each area. When spraying, spray a disposable spray on the scalp hair. No-wash spray should not be used frequently, nor can it replace washing. In order to achieve the function of the head, it is usually recommended to wash your hair 3-4 times a week. If you feel uncomfortable when using the leave-alone spray, please stop using it immediately and wash your hair in time.
