Thinning hair is a terrible blow for men who are very particular about their looks and especially their crowning glory. While there are many shampoos advertising that they could treat thinning hair, in truth, these products only give the illusion of fuller hair by adding body and fullness to hair and by promoting very deep cleansing action to arrest hair loss.
The best shampoos for thinning hair are those that are not alkaline-based. Alkaline-based shampoos cause hair to dry out, so that it becomes very stiff and brittle. Because of the increased fragility of the hair strand, it easily falls out or breaks even with gentle combing and brushing. It is best to choose a more acidic shampoo that is close to the pH level of the hair, which is 4.5 to 5.5.
Another good shampoo for thinning hair should contain ingredients that counteract the effects of dihydrotestosterone (DHT). Produced from the interaction between the hormone testosterone and the enzyme 5-alpha-reductase, DHT actually inhibits hair growth at the follicle. So an excellent shampoo should be one that prevents the effects of DHT.
Some of the highly recommended shampoos that have been found to be very effective in giving body to the hair as well as counteracting DHT are Progaine, Revivogen, HairGenesis, Nisim and DHT Shampoo Cleansing System.
