So the basic question now comes down to the effectiveness of these shampoos which are proliferating the market today.
There are several reasons why some people say that they don’t work while others say that they do.
First, it could be that the shampoo was not the perfect match for the cause of their hair loss. For example, if the hair loss is due to DHT then the user definitely needs saw palmetto in their shampoo in order to boost the chances of reducing hair loss.
So even if they use a product that helps stimulate growth if their hair follicles are having large doses of DHT, they may not see any good results. Secondly, products that contain harmful ingredients can undo all the positive effects of the healthy ingredients.
Some hair loss shampoos, usually those that have lower prices, contain sulfates or parabens just to increase the lather of the shampoo. These, however, can irritate and dry the scalp which can exacerbate hair loss. Studies have also reported them to be linked to certain forms of cancer which are a more serious problem than hair loss.
