Most product advertising that claims to produce dramatic results will show a photo of a balding person with thin hair next to a photo of the same person with thicker hair. Do these photos lie? Well, yes they do.
You can prove it yourself. Take a photo of a head with thinning hair using a flash camera and then photograph the same head without the flash. The photo with the flash will look like a bald head and the photo without the flash will look like more hair.
If the products or services are really legitimate, there should be dozens of photos, if not hundreds or thousands.
Many hair loss products claim to be able to restore hair through the use of drugs, herbal lotions or other exotic applications like lights, lasers or electrical fields. While many of these products have been around for years, there is little evidence that they can restore hair.
