Why do you say that? I can elaborate on it in several points.
First of all, the ingredients of shampoo generally do not contain any so-called Chinese medicine.
No matter what ingredients are contained in the daily shampoo, there are generally three pieces: main surfactant (such as ammonium dodecyl sulfate and ammonium dodecyl ether sulfate, which have degreasing ability), auxiliary surfactant (such as cocoamidopropyl betaine) and maintenance additives (such as emulsified silicone oil and fatliquoring agent), because the essential function of shampoo is cleaning. These components are basically chemical components, and mainly clean chemical components, which are difficult to be compatible with traditional Chinese medicine. Even if some shampoos do add some pharmaceutical ingredients, most of them are bactericidal. For example, ketoconazole commonly used in dandruff shampoo, or extracts from plants such as Platycladus orientalis can also be added. There is sterilization effect, and it has nothing to do with preventing hair loss.
Well, to take a step back, assuming that shampoo manufacturers have mastered the core technology and perfectly blended anti-alopecia drugs (usually Chinese medicine) in a way I don't know, should the effect be there? It's not good either. Shampooing is a relatively fast-paced thing. Shampoo should be applied to the hair for no more than 3 minutes, and then it will be cleaned by water. This short period of time, even if it really contains pharmaceutical ingredients, basically does not play any role. When we apply hair tonic, the hair tonic will contact the scalp for more than half an hour, and some beauty treatments will not be less than 10 minute. No matter how you look at it, you won't absorb anything during shampoo.
Ok, let's go back 100 step. Suppose you are a person who loves to wash your hair for more than half an hour at a time, which may not be helpful for your hair loss. Many men suffer from serious hair loss, which is closely related to DHT (androgen metabolite) in the body. DHT is produced continuously by itself, and its root lies in androgen metabolism. Unless it is uprooted, it can't be stopped-yes, if you plan to castrate, you can basically get rid of hair loss.
