There are many myths and old wives' tales about hair loss, but understanding the difference between fact and fiction is the first step to stopping hair loss.
Increased blood flow has not been found to stop or reverse hair loss, so products that claim to work in this fashion are ineffective. The proof: When healthy DHT resistant hairs from the back of the scalp are transplanted to balding areas, they thrive and grow.
Ingrown hairs are the result of clogged follicles. Hair loss is not. Opening the pores with shampoos or other hair care products may prevent ingrown hairs, but will not stop or reverse hair loss.
It's true that certain diet deficiencies can cause temporary hair shedding but such deficiencies are very rare. Even if you have the best nutrition and take supplements that claim to provide your hair with extra nutrients unless you treat the root cause of hair loss, DHT you can't reverse hair loss and prompt the growth of healthy, normal hair.
Although mites are found on the scalp as well as in our beds and on our pillows, there is no scientific evidence that their presence is correlated with hair loss. Products that claim to kill mites or other organisms have not shown to regrow hair.
