Shampoo applied directly to the scalp will not cause hair loss, but only if the shampoo used does not contain ingredients that can cause scalp irritation and if the shampoo is a regular and approved product. As long as the shampoo used is non-allergenic and of a regular brand that has not expired, there is no difference between applying it directly and rubbing it into the foam.

1. Conclusion: regular non-allergic shampoo will not, expired unqualified may be. The shampoo we usually use, if it is a more reliable brand, and the production date has not expired, such a direct application is not affected. However, it has many brands, and different ingredients, can not guarantee that all shampoos are safe, but some shampoos can over prevent hair loss.

2. Some of the more special shampoos will contain some drugs or special ingredients, it may lead to scalp allergies, if the hair follicles are irritated or damaged, it may increase the chances of hair loss. Then choose shampoo, try not to choose some messy miscellaneous brands, the bigger the brand the more credible a little, and the so-called hair growth shampoo, anti-hair loss shampoo, etc. These should be carefully selected.

3. In addition about hair loss we should also be rational, because under normal circumstances each person's daily hair loss is 70-100, that is to say, no matter what shampoo will be hair loss, do not think that hair loss is the problem of shampoo, but if the number of hair is particularly large and serious, it is really necessary to be careful some best to find the cause.
