If a bottle of shampoo can really prevent hair loss, it must meet the following conditions:

1, inhibiting DHT (a male hormone)

2, sterilization, anti-inflammatory effect

3, it is beneficial to balance the scalp environment and reduce the stimulation to hair follicles.

4. Promote scalp blood circulation

5. It contains some special ingredients that can promote hair growth.

In fact, it is good that most shampoo water has one function now. You know, in fact, the main function of shampoo is to clean the oil and dust on the surface of hair and scalp.

From ancient times to now, our demand for shampoo is cleaning, such as Gleditsia sinensis, plant ash, etc., which is nothing more than sterilization, anti-inflammatory and cleaning.

As for making hair more supple and dandruff-free, these are some icing on the cake effects.

Hair loss, more seriously, is more like a disease, or a chronic disease. Special treatment is needed, and shampoo alone can't play a therapeutic role.

For example, the shampoo containing ginger, Polygonum multiflorum, vitamins and minerals, which is particularly popular in the market now, actually has no scientific basis to prove that it has the effect of preventing hair loss.

Some extracts from ginger shampoo, such as gingerol, can sterilize the scalp. However, gingerol in ginger can inhibit hair growth.

Polygonum multiflorum Thunb has certain toxicity, so it should be used with caution. Every year, people are poisoned by eating Polygonum multiflorum Thunb.

Having said that, I actually want to tell you that no shampoo has the effect of preventing hair loss.

If it's because of nutritional alopecia or physical alopecia, we just need to improve our eating habits, routine and living habits. There is really no need to choose any shampoo for hair growth.

As for congenital alopecia, I think it's better to see a doctor. Otherwise, you may end up with a hair transplant.
