Are there shampoos that really work that help grow hair more and stronger?

As to shampoo, I would suggest you ask your barber or hairdresser for suggestions as some shampoos are harsh. Hair is made of protein but is susceptible to elevated testosterone levels. Male pattern baldness or male hair loss is more common in males with higher testosterone levels. If you have a concern about hair loss, I would suggest you see a dermatologist as there are good products to help re-grow hair.
