While it's true that there are many shampoo manufacturers that claim superiority over the other, knowing which shampoo could bring out the best in your hair is such difficult to find out. So if you're on the search for the best shampoo for your healthy hair, think the "what" of these ads and check how the products could generate greater results for your hair. Yes, it's undeniable that all marketing companies would claim their best for their products so be cautious. Be a critical consumer and pick the best. Remember, your hair is your crown of beauty so that means, extreme care is needed.

The truth is that there are four main problems that vitamin-infused shampoos are meant to cure:

Vitamins in shampoos are supposed to halt slow growth of your hair, graying of hair, hair loss, and general loss of health of your hair.

Vitamin-infused shampoos can either have a specific vitamin or multivitamins in their solution, some herbal supplements or a special ingredient known only to the manufacturer but which they say is a winner of a substance. Sometimes, you may see some famous names in the hairstyling world endorsing a specific shampoo which they claim is THE best in the market. All these choices can leave an ordinary consumer bewildered. So what is the truth?

Vitamins in shampoos can leave your scalp and hair healthier through repeated use. There is an issue on this claim actually. The truth is that most of the manufacturers of these shampoos rely on testimonials from "satisfied users" to back up their claim. Testimonials are not automatically false, but to provide conclusive proof that a claim is true for a certain population of people, controlled studies have to be done so that controlled results can be produced. If you had to choose between believing a testimonial from a "satisfied user" known only by her initials, and a controlled study done by a reputable testing center, which would you believe? Obviously, the later, right?

No conclusive evidence that vitamins applied externally to your hair via a shampoo will restore the health of your hair. It is generally accepted in medical circles that a lack of appropriate nutrition in your body can change the health of your hair for the worse. However, to claim that applying vitamins directly on the hair will bring back health and vitality to your hair is not based on any body of firm scientific evidence at present.

With the abovementioned 4 issues, a scientific fact does exist which puts doubt on the claim that vitamin-enriched shampoos can produce healthier hair -that hair is already dead when it shoots up out of our scalp. That is why when you have a haircut you cannot feel pain - there are no nerve endings connecting your hair shaft to your body anymore. For this reason, some scientific experts doubt very much that vitamin-enriched shampoos are absorbed by your hair, and make the hair and scalp healthier through continuous use. Last word of advice is for you to visit a doctor when you have hair issues.
